Re[4]: [PVFS-users] Re: ROMIO on PVFS

RR> Is this all on the same node?

There were two ways to create that large file:
1) It was written from a Fortran sequential
program using the Fortran open(). I don't know
if in this case PVFS would write the entire file
to one node.
2) It was written from a MPI Fortran program
using MPI_FILE_OPEN(), MPI_SET_VIEW(), MPI_FILE_WRITE().
This time the file should be written to different
nodes.

For both files created in the above two ways,
ls *.slc does not work.

RR> Does the file show up in just "ls -l"?

Yes.

RR> Is it visible on other nodes?

Yes, using ls. But no, using ls *.slc

RR> What "ls" are you using?  Is it built into your shell?

The Linux ls. I am not sure if it is built into my shell.
I am not sure if I understand this question.

RR> Could you send an strace of both the failing and successful commands?

Not sure what you wanted.


Thanks,
