This PR extends the (semi)-struct matrix/vector IO functions added on #583 with GPU support. Additionally: * Fix regression tests on Lassen. * Read data values into host memory * Update Umatrix read algorithm when the ParCSRMatrix is expected to live on the device * Reset deallocated pointers at hypre_IJMatrixDestroyParCSR to NULL * Clone rownnz info if present on a CSRMatrix * Reduce memory transfer and remove unused variables * Fix bug with -print option * Build rownnz info also when the ParCSRMatrix is in assembled state * Remove a few instances of "return ierr" * Refactor (s)struct IO - code works with cuda and without UM * Add executables to gitignore |
