Tensile 4.41.0 for ROCm 6.2.0

Additions

• new tuning script to summarize rocBLAS log file
• new environment variable to test fixed grid size with Stream-K kernels
• new Stream-K dynamic mode to run large problems at slightly reduced CU count if it improves work division and power
• add reject conditions for SourceKernel + PrefetchGlobalRead/LoopDoWhile
• add reject condition for PreloadKernelArguments (disable PreloadKernelArguments if not supported (instead of rejecting kernel generation))
• support NT flag for global load and store for gfx94x
• new Kernarg preloading feature (DelayRemainingArgument: initiate the load of the remaining (non-preloaded) arguments, updated AsmCaps, AsmRegisterPool to track registers for arguments and preload)
• add option for rotating buffers timing with cache eviction
• add predicate for arithmetic intensity
• add DirectToVgpr + packing for f8/f16 + TLU cases
• enable negative values for ExtraLatencyForLR to reduce interval of local read and wait for DTV
• add test cases for DirectToVgpr + packing
• add batch support for Stream-K kernels and new test cases
• new tuning scripts to analyze rocblas-bench results and remove tuned sizes from liblogic
• enable VgprForLocalReadPacking + PrefetchLocalRead=1 (removed the reject condition for VFLRP + PLR=1, added test cases for VFLRP + PLR=1)
• support VectorWidthB (new parameter VectorWidthB)
• support VectorWidth + non SourceSwap
• add test cases for VectorWidthB, VectorWidth + non SourceSwap
• add code owners file
• new environment variables to dynamically adjust number of CUs used in Stream-K
• add new parameters to specify global load width for A and B separately (GlobalLoadVectorWidthA, B (effective with GlobalReadVectorWidth=-1))
• add xf32 option to rocblas-bench input creator

Optimizations

• initialization optimizations (reordered init code for PreloadKernelArguments opt, used s_mov_b64 for 64 bit address copy, used v_mov_b64/ds_read_b64 for C register initialization, added undefine AddressC/D with PreloadKernelArguments, optimized waitcnt for prefetch global read with DirectToVgpr, refactored waitcnt code for DTV and moved all asm related code to KernelWriterAssembly.py)
• optimize temp vgpr allocation for ClusterLocalRead (added if condition to allocate temp vgpr only for 8bit datatype)
• reverse MFMA order in inner loop for odd outer iteration
• optimize waitcnt lgkmcnt for 1LDSBuffer + PGR>1 (removed redundant waitcnt lgkmcnt after 1LDSBuffer sync)
• enhance maximum value of DepthU to 1024 (used globalParameters MaxDepthU to define maximum value of DepthU)

Changes

• update rocBLAS-bench-input-create script (added number of iteration based on performance, rotating buffer flag)
• limit build threads based on CPUs/RAM available on system (for tests)
• update required workspace size for Stream-K, skip kernel initialization when possible
• use fallback libraries for archs without optimized logic
• use hipMemcpyAsync for validation (replace hipMemcpy with hipMemcpyAsync + hipStreamSynchronize in ReferenceValidator)
• remove OCL tests
• disable HostLibraryTests
• reduce extended test time by removing extra parameters in the test config files
• disable InitAccVgprOpt for Stream-K
• skip sgemm 64bit offset tests for gfx94x
• skip DTV, DTL, LSU+MFMA tests for gfx908
• increase extended test timeout to 720 min
• update xfail test (1sum tests only failing on gfx90a)
• update lib logic convertor script
• test limiting CI threads for only gfx11
• WGM related kernargs are removed if they are not needed (WGM=-1,0,1)
• cleanup on unused old code, mostly related to old client
• change GSUA to SingleBuffer if GlobalSplitU=1 + MultipleBuffer, instead of rejecting it
• update efficiency script for new architecture and xf32 datatype
• re-enable negative values for WorkGroupMapping (asm kernel only)
• disable HW monitor for aquvavanjaram941
• pre-apply offsets for strided batch kernels
• update tensile build with 16 threads

Fixes

• fix WorkspaceCheck implementation when used in rocBLAS
• ignore asm cap check for kernel arg preload for rocm6.0 and older
• fix Stream-K partials cache behavior
• fix MasterSolutionLibrary indexing for multiple architecture build
• fix memory allocation fail with FlushMemorySize + StridedBatched/Batched cases (multiply batch count size when calculating array size)
• fix BufferLoad=False with Stream-K
• fix mismatch issue with GlobalReadCoalesceGroup
• fix rocblas build fail on gfx11 (used state["ISA"] for reject conditions instead of globalParameters["CurrentISA"])
• fix for LdsPad auto (fixed incorrect value assignment for autoAdjusted, set LdsBlockSizePerPadA or B = 0 if stride is not power of 2)
• fix inacurate vgpr allocation for ClusterLocalRead
• fix mismatch issue with LdsBlockSizePerPad + MT1(or 0) not power of 2
• fix mismatch issue with InitAccOpt + InnerUnroll (use const 0 for src1 of MFMA only if index of innerUnrll (iui) is 0)
• fix HostLibraryTests on gfx942 and gfx941
• fix LLVM crash issue
• fix for newer windows vcpkg msgpack and vcpkg version package name
• fix an error with DisableKernelPieces + 32bit ShadowLimit
