This initial work via opt-in configure option enables offloading of some sgemm, dgemm, cgemm, zgemm operations to AMD GPUs via AMD's rocBLAS. It hence requires a working ROCm software stack and ROCm-enabled accelerator.
After enabling offloading capability, the default is "never offload". Offloading can be controlled through three environment variables:
BLIS_OFFLOAD=[never,always,thresh] - thresh enables threshold-dependent offloading
BLIS_OFFLOAD_SGEMM_THRESH=$number1 the threshold of MN size of sgemm after which offloading should be attempted - must be specified
BLIS_OFFLOAD_DGEMM_THRESH=$number2 the threshold of MN size of dgemm after which offloading should be attempted - must be specified
BLIS_OFFLOAD_CGEMM_THRESH=$number3 the threshold of MN size of cgemm after which offloading should be attempted - must be specified
BLIS_OFFLOAD_ZGEMM_THRESH=$number4 the threshold of MN size of zgemm after which offloading should be attempted - must be specified
Currently known limitations:
