Uses blocking collective MPI output routine to write array of integers. Only master process will do the writing, other processes behave as if the provided length parameter was zero. The integers are written at the master's file position, which gets updated. Positions of other processes in the file remain as they were.
- Parameters
-
| [in] | fh | File handle as returned by mpi_mod_file_open_*. |
| [in] | array | Integer array to write. |
| [in] | length | Number of elements in the array. |

Write block-cyclically distributed matrix to a stream file.
- Authors

- 2019
Assumes ScaLAPACK-compatible row-major (!) block-cyclic distribution. Writes the data at the master process file position, which it first broadcasts to other processes.
- Warning
- At the moment, there is a limitation on the element count of the local portion of the distributed matrix, which mustn't exceed 2**31 elements (i.e. 16 GiB).
- Parameters
-
| [in] | fh | File handle as returned by mpi_mod_file_open_*. |
| [in] | m | Number of rows in the distributed matrix. |
| [in] | n | Number of columns in the distributed matrix. |
| [in] | nprow | Number of rows in the process grid. |
| [in] | npcol | Number of columns in the process grid. |
| [in] | rb | Block row count. |
| [in] | cb | Block column column. |
| [in] | locA | Local portion of the distributed matrix. |
| [in] | myrows | Number of rows in locA. |
| [in] | mycols | Number of columns in locA. |
| [in] | comm_opt | Optional communicator on which the file is shared (MPI world used if not provided). |
