rocm-6.3.1

ROCm release v6.3.1

TransferBench v1.58.00

v1.58.00

Fixed

• Fixed broken specific DMA-engine copies

rocm-6.3.0

ROCm release v6.3.0

TransferBench v1.57.01

v1.57.01

Added

• Re-added "scaling" GPU GFX preset benchmark, which tests copies from GPU to other devices using varying
  number of CUs.

TransferBench v1.57.00

v1.57.00

Modified

• Removing use of default starship operator / C++20 requirement to enable compilation of more OSs
• Changing how version is reported. Client version is now just last two digits, and increments only if
  no changes are made to the backend header-only library file, and resets to 0 when header is updated
• GFX_SINGLE_TEAM=0 is set by default

TransferBench v1.56

v1.56

Fixed

• Fixed bug when using interactive mode. Interactive mode now starts prior to all warmup iterations

TransferBench v1.55

v1.55

Fixed

• Fixed missing header error when compiling on CentOS
• Fixed issues when using multi-stream mode for GFX executor

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.

TransferBench v1.53

v1.53

Added

• Added ability to specify NULL for sweep preset as source or destination memory type

TransferBench v1.52

Added

• Added USE_HSA_DMA env var to switch to using hsa_amd_memory_async_copy instead of hipMemcpyAsync for DMA execution
• Added ability to set USE_GPU_DMA env var for a2a benchmark
• Adding check for large BAR enablement for GPU devices during topology check

Fixed

• Potential memory leak if HSA reports 0 hops between GPUs and CPUs
