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.
