Hello,
I am trying to multiply two matrixs.
Matrix A : 1 row & 7180 columns & 1341 elements.
Matrix B : 7180 rows & 10001 columns & 372623 elements.
But segment fault occurs when calling SPMM.
The error occurs when calling mkl_sparse_spmm with the two matrixs all in CSR format, while the two matrixs seems (the matrix is big so that I can not confirm the correctness) in correct format by printing it (mkl_sparse_s_export_csr).
However, I can not reproduce it in a simple case.
Any idea what the problem is? Is there any useful information?
Thank you very much in advance.
