rocksdb shared_block_cache参数
rocksdb shared_block_cache参数RocksDB 基于SSD的模块，提供了多个配置参数，可以根据应用的需求进行调整，以获得最佳的性能和存储效率。
其中之一是shared_block_cache 参数。
本文将对 shared_block_cache 进行详细的介绍和解释。
RocksDB 是一个开源的持久化键值存储引擎，可以应用于多种场景，包括云计算系统、数据库系统等。
在处理大规模数据时，性能和效率是关键指标之一。
RocksDB 提供了 shared_block_cache 这个参数，可以用于优化读取性能。
shared_block_cache 是 RocksDB 中一个非常重要的参数，它指定了是否使用一个共享的内存块缓存来加速读取操作。
在默认情况下，RocksDB 会为每个数据文件分配一个独立的内存块缓存。
而当shared_block_cache 参数被启用时，RocksDB 将为所有数据文件使用一个共享的内存块缓存。
为了更好地理解 shared_block_cache 参数的作用，我们可以将其与独立的内存块缓存进行对比。
在使用独立的内存块缓存时，每个数据文件都有自己的内存块缓存，这样可以减少不同数据文件之间的竞争，从而提高并发读取的性能。
然而，这也会导致整体内存的占用较高。
而当 shared_block_cache 参数被启用时，所有的数据文件将共享同一个内存块缓存。
这意味着所有的数据文件都可以共享相同的内存资源，而不需要为每个数据文件都分配额外的内存块缓存。
这种方式可以节省内存空间，并且提高整体的读取性能。
然而，值得注意的是，启用 shared_block_cache 参数可能会导致不同数据文件之间的竞争增加，从而降低并发读取的性能。
因此，在确定是否启用 shared_block_cache 参数时，需要根据具体场景进行评估和测试。
在 RocksDB 中启用 shared_block_cache 参数非常简单，只需要在配置文件中进行相应的设置即可。

There are technical articles about installation, troubleshooting, specifications, and more. Plus, you’ll find company contact information and Waves Support news.About the Abbey Road TG Mastering Chain PluginAbbey Road TG Mastering Chain is a modular plugin for mastering and mixing, modeled after the original EMITG12410 Transfer Console used in all Abbey Road Studios’ mastering suites from the early ‘70s to this day.The plugin can be used for both mastering and mixing – on the master bus, on groups or on individual tracks – to lend them the distinct sound of the original console, as heard on albums from Pink Floyd’s Dark Side of the Moon to Radiohead’s OK Computer and beyond.Like the original EMI TG12410 console, the Abbey Road TG Mastering Chain plugin consists of the following modules: 1.TG12411 Input Module – handles all input tasks (phase, L/R balance, etc.)2.TG12412 Tone Module – a musical, versatile 4-band EQ with 5 filter types per band3.T G12413 Limiter Module – includes three compressor/limiter types:OriginalAggressive and ‘dirty’, precision-modeled after the unit’s original Zener diode limiter ModernPristine-sounding, with higher levels of perceived loudness; an original Waves andAbbey Road designL imitBased on the limiter mode of the console’s original Zener diode. The knee is muchharder compared to the “Original” compressor [“Original”]4.TG12414 Filter Module – includes low-pass & high-pass filters and a presence bell5.TG12416 Output Module – complete with a spreader (stereo spread enhancer)The individual modules can be re-ordered (except for the Input and Output modules which remain at the start and end of the chain) and switched on/off, letting you create differently ordered chains and a modular, customizable processing flow.The Abbey Road TG Mastering Chain plugin also comes with the Abbey Road TG Meter Bridge component (a separate plugin), which is based on the original set of PPM, VU and phase correlation meters used by Abbey Road’sengineers in conjunction with the EMI TG12410 Transfer Console.QUICK STARTThis quick start guide suggests the basics of how to use the Abbey Road TG Mastering Chain plugin when masteringa track. To learn more about controlling the plugin and how to fine-tune its sound, in mixing as well as mastering sessions, read the “Interface and Controls” section later in this user guide.1.Insert the plugin on the master channel. (If you are using the plugin to mix rather than master, you can of courseinsert it on any individual channel or group.)e the TG12411 Input module to adjust input gain or to handle phase and balance issues (for more on how to dothis, see the TG12411 Input Module section later in this user guide). You may also want to use the module’s Tape Equalizer control for its unique sonic color.3.Open the TG Meter Bridge on any channel.4.Set the Meter bridge to read the instance you are working on.5.Adjust the input level to get a good 0VU input reading on the meter bridge. This will assure enough headroom.6.Experiment with the TG12412 Tone module to get a good frequency balance.7.When mastering a track to meet modern mastering requirements, we recommend you use the Modern mode ofthe TG12413 Limiter module, which is best suited for today’s mastering requirements.8.In the TG12413 Limiter module, experiment with the Recovery control to get the best time-constant results forthe song you are working on. 3, 4 and 5 are the ones we’ve found most suitable for mastering: 3 for more upbeat songs, 5 for slower ones.9.The key to getting a good compression sound is playing with the TG12413 Limiter module’s Ratio and Mix controls,in order to achieve the best compression balance. Try somewhere around Ratio = 30–40 and Mix = 40–50.10.In the Limiter’s expanded view, turn on the high-pass filter and find a good-sounding point anywhere between 120–200 Hz. This will make the compression better correlated to the music (as sub frequencies will tend to suffocate thecompression).e the TG12414 Filter module to clean unwanted frequency ranges and add some presence if needed.12.A/B between the unprocessed and processed signal, using the bypass control. Make sure you adjust the overalllevel of processed signal to match the unprocessed level, so the A/B comparison does not introduce gain changes which might easily throw you off.COMPONENTSThe Abbey Road TG Mastering Chain plugin has four components:>Mono>Stereo>Live Mono>Live StereoThe Live components are optimized fo r live use, where extremely low latency and minimal CPU usage are required. The non-Live components have up-sampling at lower sample rates; the Live components remove the up-sampling in order to reduce latency. The non-Live components use very sharp linear phase FIR sidechain filters that introduce latency; the Live components use non-linear phase IIR sidechain filters to minimize both latency and CPU usage.WAVESYSTEM TOOLBARUse the bar at the top of the plugin to save and load presets, compare settings, undo and redo steps, and resize theplugin. To learn more, click the icon at the upper-right corner of the window and open the WaveSystem Guide.INTERFACEand Filter modules by dragging each to the desired location within the chain.MODULES AND CONTROLSControls Available in All ModulesThe following controls appear at the top of each module (except Output):On/OffEach of the plugin’s modules can be turned on or off by pressing this button. While off, the module does not consume any CPU power. All modules are first turned off by default. To turn each on, click on the individual module’s on/off control. (Please note that in the plugin’s Live components, turning a module off will not change CPU consumption.)Expand/CollapseExpands/collapses the module.ST/DUO/MS (Stereo component only)In the plugin’s stereo component, within each module, you can choose between three modes of processing a stereo signal: Stereo (ST), Duo, and Mid-Sides (MS).Regardless of a module’s stereo mode – ST, DUO, or MS – its output is always stereo. If needed, it will be converted into MS at the input of the next module in the chain. This allows re-ordering of the modules on the fly with no impact on thestereo processing.The collapsed view of each module shows just one control per function (e.g., frequency, gain), regardless of whether the signal is mono or stereo.The expanded view of each stereo module shows each control twice. In Stereo and Duo modes, the left and right control sections are labeled L and R. In MS mode, the labels will change to M and S, for mid and side.LinkIn the collapsed view, the left and right (or mid and side) channels are always linked: that is, both channels are controlled together, and by default, with the same values.The expanded view of each module includes a square Link button at the top. When Link is on, the controls for both sides remain linked. Switches (such as EQ type, filter on/off, SC on/off) remain linked as well: clicking a left or right switch will set both controls to the same value.To decouple the left and right (or mid and side) controls, simply turn the Link button off. This will allow you to adjust each side separately. Once L and R are re-linked, any offset between them will be maintained.Expanded Module NavigationOnce a module is expanded, you can navigate directly to the expanded view of any other module in the plugin by clicking on any of the module navigation buttons at the top.Track NameEach instance of the plugin will show the track name it is instantiated on. You can use this information to move between different meter readings on the TG Meter Bridge.Please note that some DAWs do not support track naming. When working with such DAWs, you can fill in the TrackName manually.TG12411 Input ModuleCollapsed View Expanded View (Stereo)InputControls the input level to the plugin.Range: -24 to +24 dB in 0.1-dB increments.Tape EqualizerApplies a filter to flatten out the frequency spectrum.Originally, in the hardware domain, this was done when playing back the track from NAB or IEC tape machines at either 7.5 or 15 ips, in order to provide the equalization required for playing NAB-equalized tape on an IEC machine and vice versa.In your digital mixes, you will not need to use this control for that historic purpose. We have decided to keep this control, however, due to its great sonic character, and you may find that it gives your tracks interesting sonic characteristics. Options:NAB-to-IEC: 7.5 ips and 15 ipsIEC-to-NAB: 15 ips and 7.5 ipsDefault: FlatPoleFlips the input phase by 180 degrees.The Stereo component includes Pole L and Pole R. Clicking on Pole L will only flip the phase for the Left channel. To flip the overall phase for both channels, you will have to expand the Input module and click on Pole R as well.Default: OffTransposeTransposes the Left and Right channels.Default: OffBalance (BAL)Changes the level relations between Left and Right channels. Moving towards the right side will increase the level on the right and decrease the level on the left, and vice versa.Range: -5 to +5 dB in 0.05-dB increments.Default: 0PhaseShifts the phase of one channel relative to the other by 90 degrees. This is good for stereo tracks that have phase correlation problems between Left and Right.Options: Stereo, L+90, R+90Default: StereoTG12412 Tone ModuleCollapsed View Expanded View (Stereo)The Tone module is a highly musical and versatile 4-band EQ. Each band has 5 fixed cutoff points and 5 filter shapes. FrequencyDetermines the cutoff point for each band:32, 45, 64, 91, 128 HzBand 1Band 2181, 256, 362, 512, 724 HzBand 31.02, 1.45,2.05, 2.6,3.25 kHzBand 44.1,5.8, 8.1, 11, 16 kHzGainDetermines the level for each band.Range: -10 to +10 dB in 0.05-dB increments.ShapeDetermines the filter type for each band:Low A low-shelf filterBL Blunt – a very wide bell filterMED Medium Blunt – a moderately wide bell filterSH Sharp – a very narrow bell filterHigh A high-shelf filterBand On/OffEach band has a dedicated on/off switch, so you can easily monitor the processing of each band.Band Monitoring (expanded view only)Clicking this button will allow you to solo the band and hear its filtering separately.TG12413 Limiter ModuleCollapsed View Expanded View (Stereo)The Limiter module lets you choose between the module’s original Zener compressor and limiter, and a modern compressor designed to meet modern mastering requirements. It is coupled with linear phase filters for super-clean filtering, and phase-coherent sidechain filters.TypeToggles between 3 modes of dynamic processing:Original The TG12413’s original Zener diode compressor.Modern VCA-based compressor, newly designed with low-level compression inmind in order to meet modern-day mastering requirements.Limit This is the limiter mode of the Zener diode. The knee is much hardercompared to the compressor [“Original”]. Please note that this is not abrick-wall limiter: transients are expected to pass.Please note: The Type selector is the only control in this module that cannot be set differently on the L and R stereo channels: for example, if the Type control is set to Modern on the L channel, it will be set to Modern on the R channel as well.RecoverySelects between six recovery times, depending on the Type you use (Original or Modern). These recovery times are very hard to put in terms of exact milliseconds. Think of them in the following terms: the higher the recovery state, the longer the attack/release time. You will need to experiment in order to hear the exact difference.Range: 1-6Default: 3Make UpUse this control to manually adjust the makeup gain of the compressed signal. The plugin does apply automatic makeup gain to the compressed signal, and for most input signals it will do a good job; but sometimes you need a minor tweakto make it perfect.Please note that the makeup gain is applied on the compressed signal only, not on the direct signal. This is importantto know when the Mix control (see below) is set to anything other than 100, meaning that your signal blends both the compressed and the direct signal.Range: -12 to +12 dBDefault: 0 dBRatioSets a ratio to the VCA input/output curve. For example, if for a certain point on the VCA curve an input of -12 dBFS will result in an output of -24 dBFS at 100 ratio, then at 50 ratio the same input of -12 dBFS will result in -18 dBFS. Range: 1–100Default: 50Sidechain Filters (SC Filters)As an original addition to the Waves Abbey Road TG Mastering Chain plugin, we have added three linear phase filters to the dynamics sidechain of the compressor/limiter module. Linear phase filters are important to keep the phase aligned in the sidechain, so that the plugin’s attack/release will work well on phase-aligned signals.(Please note that the linear phase FIR sidechain filters are used only in the plugin’s ‘regular’ Mono and Stereo components, not in the two Live components that are optimized for live use. In the Live components, the linear phase FIR filters are replaced with non-linear phase IIR filters.)The module’s collapsed view includes a red global On/Off switch for all the sidechain filters.The sidechain filters are all off by default. Engage each by clicking the square button next to its name. Once you engage one of the sidechain filters, it will become available for you on both the collapsed and the expanded views. Clicking the global On/Off control will turn all sidechain filters off: this will help you easily monitor the addition of the sidechain filtersto the compression sound.The following sidechain filters are available in the module’s expanded view:High Pass25 Hz–1Khz; 48 dB per octaveBell100 Hz–12 kHz; -40 to +40 dB in 0.1-dB incrementsLow Pass 1 kHz–22 kHz; 48 dB per octaveC licking this button (in the expanded view) will enable you to separately monitor the sidechain, including thePlease note: In the TG12413 Limiter module, the ST/DUO/MS selection determines how the sidechain is processed: StereoLeft and right channels are summed in the sidechain. The sidechain values are the same forleft and right, so dynamic processing will apply equally to both channels.DuoLeft and right channels of the sidechain are processed separately, so dynamic processing maynot be the same for the left and right channels.MSMid and side channels of the sidechain are processed separately, so dynamic processing maynot be the same for the mid and side channels.*MixDetermines the balance between the uncompressed and the compressed signal.GRGain reduction meter.* Please note: Pro Tools allows only a mono sidechain.TG12414 Filter ModuleCollapsed View Expanded View (Stereo)The Filter module is a simple, highly musical 3-band filter with high-pass, low-pass and presence controls.High PassChoose from 4 selected HP frequencies: 40 Hz, 63 Hz, 80 Hz, 110 Hz‘Low’ functions as off.PresenceChoose from 8 fixed cutoff points of a Med Blunt bell: 0.5 khz, 0.8 kHz, 1.2 kHz, 1.8 kHz, 2.8 kHz, 4.2 kHz, 6.5 kHz, 10 kHz dB range: -10 to +10 dB in 0.1-dB increments.Low PassChoose from 5 fixed cutoff points: 20 kHz, 15 kHz, 12 kHz, 10 kHz, 8 kHz‘High’ functions as off.Spreaderthe original EMI TG12416 unit.

This is the Abbey Road Meter Bridge. Using this plugin, you can easily open all three meters at once, just like Abbey Road’s engineers.We have added three metering options to the Abbey Road TG Meter Bridge:IN InputGR Gain ReductionOUT OutputConnecting the Meter Bridge with the Abbey Road TG Mastering Chain PluginOne instance of the Abbey Road TG Meter Bridge can communicate with all instances of the Abbey Road TG Mastering Chain plugin, inserted on any track in the same session.If you open the Meter Bridge on a particular track, it will monitor that track by default.To meter a different track in the same session, simply select its name in the “Track Name” window of the Meter Bridge interface; you are now connected to the instance of the Abbey Road TG Mastering Chain plugin that is open on thatother track, and can meter its input, gain reduction and output.。

compatible with this Roll are listed.Other Rolls will likely work,but have not been tested by the maintainer of this Roll.Chapter2.Installing2.1.On a New ServerThe hpc Roll should be installed during the initial installation of your server(or cluster).This procedure is documented in section1.2of the Rocks™usersguide.You should select the hpc Roll from the list of available rolls when you see a screen that is similar to the one below.2.2.On an Existing ServerThe hpc Roll may also be added onto an existing server(or frontend).For sake of discussion,assume that you have an iso image of the roll called hpc.iso.The following procedure will install the Roll,and after the server reboots the Roll should be fully installed and configured.$su-root#rocks add roll hpc.iso#rocks enable roll hpc#rocks-dist dist#kroll hpc|bash#init6inging mpirun from OpenMPITo interactively launch a test OpenMPI program on two processors:•Create afile in your home directory named machines,and put two

programs as a regular user(that is,not root).If you don’t have a user account on the cluster,create one for yourself,and propogate the information to the compute nodes with:#useradd username#rocks sync usersing mpirun from MPICHTo interactively launch a test MPICH program on two processors:•Create afile in your home directory named machines,and put two entries in it,such as: compute-0-0compute-0-1•Compile a test program using the MPICH environment:$cd$HOME$mkdir mpich-test$cd mpich-test$cp/opt/mpi-tests/src/mpi-ring.c.$/opt/mpich/gnu/bin/mpicc-o mpi-ring mpi-ring.c-lm•Now

is,not root).If you don’t have a user account on the cluster,create one for yourself,and propogate the information to the compute nodes with:#useradd username#rocks sync users3.3.Cluster-ForkCluster-Fork runs a command on compute nodes of your cluster.Often we want to execute parallel jobs consisting of standard UNIX commands.By"parallel"we mean the same command runs on multiple nodes of the cluster.We use these simple parallel jobs to movefiles,to run small tests, and to perform various administrative tasks.Rocks provides a simple tool for this purpose called cluster-fork.For example,to list all your processes on the compute nodes of the cluster:$cluster-fork ps-U$USERBy default,cluster-fork uses a simple series of ssh connections to launch the task serially on every compute node in the cluster.Cluster-fork is smart enough to ignore dead ually the job is"blocking":cluster-fork waits for the job to start on one node before moving to the next.By using the--bgflag you can instruct cluster-fork to start the jobs in the background.This corresponds to the"-f"sshflag.$cluster-fork--bg hostnameOften you wish to name the nodes your job is started on.This can be done by using an SQL statement or by specifying the nodes using a special shorthand.Thefirst method of naming nodes uses the SQL database on the frontend.We need an SQL statement that returns a column of node names.For example,to run a command on compute nodes in thefirst rack of your cluster exectute: $cluster-fork--query="select name from nodes where name like’compute-1-%’"[cmd] The next method of requires us to explicitly name each node.When launching a job on many nodes of a large cluster this often becomes cumbersome.We provide a special shorthand to help with this task.This shorthand,borrowed from the MPD job launcher,allows us to specify large ranges of nodes quickly and concisely.The shorthand is based on similarly-named nodes and uses the--nodes option.To specify a node rangecompute-0-0compute-0-1compute-0-2,we write--nodes=compute-0-%d:0-2.This scheme works best when the names share a common prefix,and the variables between names are numeric.Rocks compute nodes are named with such a convention.Other shorthand examples:•Discontinuous ranges:compute-0-%d:0,2-3-->compute-0-0compute-0-2compute-0-3ing•Multiple elements:compute-0-%d:0-1compute-1-%d:0-1-->compute-0-0compute-0-1compute-1-0compute-1-1•Factoring out duplicates:2*compute-0-%d:0-1compute-0-%d:2-2-->compute-0-0compute-0-0compute-0-1compute-0-1 compute-0-2$cluster-fork--nodes="compute-2-%d:0-32compute-3-%d:0-32"ps-U$USERThe previous example lists the processes for the current user on64nodes in racks two and three.Appendix A.Rocks
