Using cusolverDnSgesvd inside cuda graph APIs results in CUSOLVER_STATUS_INTERNAL_ERROR

I don’t know if this is a bug of cuda graph. Do cuda solver APIs support cuda graph? I find some examples of cublas and cusparse, but haven’t find any of cusolver yet.

Hi Ken_I. Welcome to the forum!

Most cuSOLVER routines should be compatible for now, but I’m afraid GESVD is an exception. We’re working on extending cuSOLVER to fully support CUDA graphs.

Is (C)HEEVD another one of these exceptions? See this StackOverflow question and the comments below it. Why is the CUDA Graphs compatibility of cuSolver APIs not documented?

Hi Paul,

cuSOLVER APIs for {S,D}SYEVD and {c,Z}HEEV are not graph capture-able right now. If you further explain your use case, we can see if we can find a workaround, until the routine is compatible with graph capture.

Thanks,
Christoph
