Additions
new DisableKernelPieces values to invalidate local read, local write, and global read
stream-K kernel generation, including two-tile stream-k algorithm by setting StreamK=3
feature to allow testing stream-k grid multipliers
debug output to check occupancy for Stream-K
reject condition for FractionalLoad + DepthU!=power of 2
new TENSILE_DB debugging value to dump the common kernel parameters
predicate for APU libs
new parameter (ClusterLocalRead) to turn on/off wider local read opt for TileMajorLDS
new parameter (ExtraLatencyForLR) to add extra interval between local read and wait
new logic to check LDS size with auto LdsPad(=1) and change LdsPad to 0 if LDS overflows
initialization type and general batched options to the rocblas-bench input creator script
Optimizations
enabled MFMA + LocalSplitU=4 for MT16x16
enabled (DirectToVgpr + MI4x4) and supported skinny MacroTile
optimized postGSU kernel: separate postGSU kernels for different GSU values, loop unroll for GSU loop, wider global load depending on array size, and parallel reduction depending on array size
auto LdsPad calculation for TileMajorLds + MI16x16
auto LdsPad calculation for UnrollMajorLds + MI16x16 + VectorWidth
Changes
cleared hipErrorNotFound error since it is an expected part of the search
modified hipcc search path for Linux
changed PCI ID from 32bit to 64bit for ROCm SMI HW monitor
changed LdsBlockSizePerPad to LdsBlockSizePerPadA, B to specify LBSPP separately
changed the default value of LdsPadA, B, LdsBlockSizePerPadA, B from 0 to -1
updated test cases according to parameter changes for LdsPad, LBSPP and ClusterLocalRead
Replaced std::regex with fnmatch()/PathMatchSpec as a workaround to std::regex stack overflow known bug
Fixes
hipcc compile append flag parallel-jobs=4
race condition in Stream-K that appeared with large grids and small sizes
mismatch issue with LdsPad + LdsBlockSizePerPad!=0 and TailLoop
mismatch issue with LdsPad + LdsBlockSizePerPad!=0 and SplitLds
incorrect reject condition check for DirectToLds + LdsBlockSizePerPad=-1 case
small fix for LdsPad optimization (LdsElement calculation)
