TransferBench v1.50

Added

• Adding new parallel copy preset benchmark (pcopy)
  • Usage: ./TransferBench pcopy <numBytes=64M> <#CUs=8> <srcGpu=0> <minGpus=1> <maxGpus=#GPU-1>

Fixed

• Removed non-copies DMA Transfers (this had previously been using hipMemset)
• Fixed CPU executor when operating on null destination

TransferBench v1.49

Fixes

• Enumerating previously missed DMA engines used only for CPU traffic in topology display

TransferBench v1.48

v1.48

Fixes

• Various fixes for TransferBenchCuda

Additions

• Support for targeting specific DMA engines via executor subindex (e.g. D0.1)
• Printing warnings when exeuctors are overcommited

Modifications

• USE_REMOTE_READ supported for rwrite preset benchmark

TransferBench v1.47

Fixes

• Fixing CUDA compilation

TransferBench v1.46

Fixes

• Fixing GFX_UNROLL set to 13 (past 8) on gfx906 cards

Modifications

• GFX_SINGLE_TEAM=1 by default
• Adding field showing summation of individual Transfer bandwidths for Executors

TransferBench v1.45

Additions

• Adding A2A_MODE to a2a preset (0 = copy, 1 = read-only, 2 = write-only)
• Adding GFX_UNROLL to modify GFX kernel's unroll factor
• Adding GFX_WAVE_ORDER to modify order in which wavefronts process data

Modifications

• Rewrote the GFX reduction kernel to support new wave ordering

TransferBench v1.44

Additions

• Adding rwrite preset to benchmark remote parallel writes
• Usage: ./TransferBench rwrite <numBytes=64M> <#CUs=8> <srcGpu=0> <minGpus=1> <maxGpus=3>

TransferBench v1.43

Changes

• Modifying a2a to show executor timing, as well as executor min/max bandwidth

TransferBench v1.42

Fixes

• Fixing schmoo maxNumCus optional arg parsing
• Schmoo output modified to be easier to copy

TransferBench v1.41

Additions

• Adding schmoo preset config benchmarks local/remote reads/writes/copies
  • Usage: ./TransferBench schmoo <numBytes=64M> <localIdx=0> <remoteIdx=1> <maxNumCUs=32>

Fixes

• Fixing some misreported timings when running with non-fixed number of iterations
