cusparseCsr2cscEx2_buffersize returns 0 buffer

[mboudagh]

cusparseCsr2cscEx2_buffersize returns 0 buffer size which leads to error at istat=cusparseCsr2cscEx2(…) as “istat=3”
All other input parameters are correct as far as I know. I would appreciate any comment.

cusparseCsr2cscEx2_buffersize huge buffersize

Oh, Right. Thank you very much. I fixed it. But now a question, what does bsize=0 mean? should it be always >0? In the example “/examples/CUDA-Libraries/cuSPARSE/test_sparse_cuf/tcusparsemv1.cuf” buffer is allocated if bzise>0. if it is bsize=0, the istat = cusparseCsr2cscEx2( …) returns istat=3 error. Does it has to do with :

Just for the record, if anyone has the same issue, other than checking for the correctness of the input parameters, you may compile your code with a higher version of nvhpc. Mine seems to be solved doing so.
