Does the BLAS (e.g. hipblasIdamax) function support 64-bit interface ? Thanks.

Currently hipBLAS and rocBLAS do not support the 64-bit integer interfaces. The Level 1 functions including iamax iamin with 64-bit integer form are a planned addition so should be available in a future release. We can post here when they arrive.

rocBLAS has ILP64 interfaces for Level 1 BLAS added in develop branch for future release, so work on adding these to hipBLAS can begin soon.

HI @jinz2014,

ILP64 interfaces for all L1 and L2 functions are supported in hipBLAS as of ROCm 6.2. Most L1 functions were added in 6.1.0, and the remaining ILP64 interfaces should land in the next ROCm release.

I'll close this issue now, feel free to re-open if needed.

Thanks, Daine
