[mpich-discuss] Worries with ROMIO on NFS since commit b4ab2f118d

[Eric Chamberland]

Hi M. Latham,

I have more information now.

When I try to run my example on NFS, I have the following error code:

error #812707360
Other I/O error , error stack:
ADIOI_NFS_READSTRIDED(523): Other I/O error Success

that is returned by MPI_File_read_all_begin

When I try on a local disk, everything is fine.

Here are all files about my actual build:

Hope this help to dig further into this issue.

Thanks,
