TransferBench v1.54

v1.54

Modified

• Refactored TransferBench into a header-only library combined with a thin client to facilitate the
  use of TransferBench as the backend for other applications
• Optimized how data validation is handled - this should speed up Tests with many parallel transfers as data is only
  generated once
• Preset benchmarks now no longer take in any extra command line arguments. Preset settings are only accessed via
  environment variables. Details for each preset are printed
• The a2a preset benchmark now defaults to using fine-grained memory and GFX unroll of 2
• Refactored how Transfers are launched in parallel which has reduced some CPU-side overheads
• CPU and DMA executor timing now use CPU wall clock timing instead of slowest Transfer time

Added

• New one2all preset which sweeps over all subests of parallel transfers from one GPU to others
• Adding new warnings for DMA execution relating to how HIP will default to using agents from the source memory

Removed

• CU scaling preset has been removed. Similar functionality already exists in the schmoo preset benchmark
• Preparation of source data via GFX kernel has been removed (USE_PREP_KERNEL)
• Removed GFX block-reordering (BLOCK_ORDER)
• Removed NUM_CPU_DEVICES and NUM_GPU_DEVICES from common env vars and only into the presets they apply to.
• Removed SHARED_MEM_BYTES option for GFX executor
• Removed USE_PCIE_INDEX, and SHARED_MEM_BYTES

Fixed

• Fixed a potential timing reporting issue when DMA executed Transfers end up getting serialized.
