[zeyang12-jpg]

Problem Description

machine:MI308 I set the flag HIPBLASLT_LOG_LEVEL=2&TORCH_BLAS_PREFER_HIPBLASLT=1when I run my test,the output, it can find rocblaslt_matmul from my log,does it mean that the hipblaslt_matmul is not used.

Hi @zeyang12-jpg. Internal ticket has been created to investigate your issue. Thanks!

Hi @zeyang12-jpg, thanks for reaching out. Just in case, would you be able to confirm the outputs of

echo $TORCH_BLAS_PREFER_HIPBLASLT  

please?
What kind of work load are you trying to run? A simple reproducer would be helpful.

Thanks!!
