The method cusparseSnnz
for computing the number of nonzero elements expects some pointers to write the output to. The last one should either be a host pointer or a device pointer (depending on the CUSPARSE pointer mode).
Right now, only device pointers are accepted there.
This should be fixed so that the method also accepts a host pointer.
Hi!
I did not fully get behind this one yet, but using JCusparse.cusparseSpMM_bufferSize(...) seems to segfault when releasing JNI resources. Could be me doing something wrong, but when I step through JNICALL Java_jcuda_jcusparse_JCusparse_cusparseSpMM_1bufferSizeNative(...) [1] the return value of the CUDA API call cusparseSpMM_bufferSize(...) returns "success". A few lines down that function the error is thrown when releasing pointers. I handle the call to that function the same way as I do with other CuBLAS and CuSparse functions, so I don't really see the problem (yet). I thought I'd open an issue just in case somebody has the same problem or has any clue.
Regards, Mark
