[Trilinos-Users] Problem with EpetraExt::VectorToMatrixMarketFile

[Heroux, Michael A]

Tudor,

The only requirement on this function is that MPI rank 0 be on the node that has access to the file system you are writing to.

Hi everybody.

I am trying to write an Epetra_Vector to a Matrix Market file using
VectorToMatrixMarketFile. This works if all the MPI processes run on the
front-end (presumably the only node that actually writes to disk) but
fails when other nodes are included. The corresponding read method,
MatrixMarketFileToVector, works regardless of the nature and number of
nodes used. I am using Trilinos 8.0.4.

Any suggestions would be appreciated.

Thanks in advance,
-Tudor
