This tool will extract the total number of CPU cores/threads and GPU platforms from the user's environment and utilize them in running a list of apps/args specified in the benchCFG file. Using less than the total number of CPU threads can be specified in the command line. This tool will read a list of MB/AP apps/args from the BenchCFG file and search for the specified MB/AP apps in the APP_CPU and APP_GPU directories to validate and determine platform. It will then leverage allocated threads, as specified, to run all benchmark jobs, storing results in the testData directory. Use the --help option to get a description of valid command line arguments. In support of automation, some command line arguments can be specified as modes in the BenchCFG file.
By default, a summary list of all jobs will update in the display as the program progresses. If there are a large number of jobs, then this display may not be useful and the --display_slots option can be used to display the status of each slot as the program progresses. In some cases, there will be too many slots to display, and the --display_compact option can used to further optimize the progress display.
You may need to use the --boinc_home command option to specify the BOINC home directory, which is required, since boinccmd is used. An alternative BenchCFG file can be specified with the command line option --cfg_file filename.
The --lsgpu command option can be used to display information and capability of all installed GPUs. The --purge_kernels can be used to purge all compiled kernels from the benchMT working directory.
All WUs in the WU_test directory will be used in the creation of jobs to be run, unless the --std_signals option is used, in which case, WUs in the WU_std_signal will be used. The APPS_GPU and APPS_CPU directories can have more apps than are specified to run in the BenchCFG file, but must contain apps specified in BenchCFG. The APPS_REF directory must contain a single CPU reference app with a file prefix of "ref-cpu.". The stock CPU app is suggested, as this is only used to test integrity of the results. Elapsed time analysis is expected to be limited to apps/arg combinations specified in BenchCFG. The generation of reference results can be skipped with the --no_ref option or forced with the --force_ref option. The --energy option can be used if your system has amdgpu drivers with compatible GPUs to give the energy used in running a task. In order to correctly associate a GPU card number with a BOINC device number, you must specify this with the --devmap B:C,B2:C2 option. I know of no robust way to make this mapping other than manually running each card individually and observing which card is being used. If you are running an AstroPulse app, you must specify the --astropulse option in order for it to run properly.
The results will be stored in a unique subdir of the testData directory. There is an overall run log txt file, a psv file useful for importing into an analytics tools, and the sah and stderr files for each job run. A run name can be specified with the --run_name command line option. This name will be included in the name of the testData subdirectory for the current run.
New in this Release - v2.0.0
- Complete rewrite of the core to integrate GpuItem object that was previously only used in energy mode.
- Implemented a more robust check of compute and energy compatibility for all installed GPUs. Switched from lshw to lspci and clinfo. Not working for Intel GPUs.
- Many core improvements for better robustness and style. Added reST docstrings for better supportability and improved type checking by PyCharm.
- Extend energy mode to cover Nvidia, in addition to AMD GPU's. Added max-power to psv and txt reports.
- --noBS on the command line will allow benchMT to function without a BOINC installation.
- Check devmap and give more details to help user understand mapping of BOINC Devices to Driver Card Numbers.
- Added --purge_kernels command line option to purge cached kernel files from working directory.
- Added --lsgpu command line option to display information on all installed GPUs.
- Reading BOINC's coproc_info.xml as a possible way to automate device to card mapping. Not implemented.
- Doesn't work in console of server install of Ubuntu. Need to investigate this.
- Currently, running more than one job at a time on a single GPU is not supported.
- The clinfo output for Intel GPUs doesn't seem to have a pcie id indicator based on the data I have on 1 card.
- Need to find a way to automate mapping of BOINC device number to Linux card number or PCIE ID. Results from reading coproc_info.html are available in --debug mode for experimentation.
- This package doesn't include a utility to compare AstroPulse results to a reference. If you know where a Linux version of this exists, please let me know.
- Special NV app outputs results to stdout which corrupts the benchMT updating table.
- When no GPU work is selected, benchMT still validates GPU related command line arguments.
New in Previous Release - v1.6.0
- Complete rewrite of commandline/config file option parsing. Original got complex and buggy.
- Support execution and time/energy metrics for AstroPulse apps/wus. Still no working results comparison utility, so comparison to reference results not possible.
New in Previous Release - v1.5.0
- Implemented checks of Python and Kernel version to verify compatibility.
- Implemented more robust system calls.
- Fixed an error in parsing lshw output to extract GPU names and added error checking.
- When specifying specific GPUs to be used with --gpu_devices, max_gpus is now automatically set.
- Implemented Energy metric for GPUs using amdgpu drivers.
- Code robustness improvements (path joins and key checks).
- Run completion message now includes the location of the results.
New in Previous Release - v1.4.0
- Write run_name to the psv file. Useful when wanting to analyze the data from multiple runs.
- Include Nvidia stock MB app in the distribution.
- Include error message when job fails to spawn.
New in Previous Release - v1.3.0
- SETI MB apps are now run without a shell, using shlex to parse args for the subprocess command.
- Implemented --force_ref option to force generation of reference results, even if they already exist.
- Implemented job execution with time command. Time relevant data is written to summary and psv files.
- Added job execution error checking. Bad exit status will result in updated error fields in summary/psv files and status display.
New in Previous Release - v1.2.0
- Fixed a problem with the when lock_file was created and checked. Now placed before slot initialization.
- Fixed issue where program would exit if Reference file didn't exist. Now an error message is printed and no comparison results are printed to summary files.
- Added command line option --no_ref which will not create reference results when selected. This is useful for characterizing potential reference WUs.
- Added color to status display.
- Modified so that status display will not show skipped jobs (Reference data already exists).
- Updated reference WUs in the WU_test/safe directory. Still need a WU with a Gaussian signal.
New in Previous Release - v1.1.0
- Command line options can now be specified in mode lines of the BenchCFG file. Options given on the command line will override modes specified in the CFG file.
- An alternative CFG file can now be specified as a command line option.
- Signal counts and Angle Range are now included in the psv and txt summary files.
- Remove app -device N arg if specified, since -device is automatically added based on slot assignment.
- Added --gpu_devices x,y command line option to specify which GPU devices the user would like to include in the benchmark run.
- Added a lock_file in the working directory to prevent a second occurrence of benchMT from using the same directory.
- Updated reference WUs in the WU_test/safe directory.
- Changed --ref_signals option to --std_signals for clarity.
