Hi Guys,
I have problem in reading hdf5 files with multiple cpus (IO parallel). I
use intel compilers (version 11.0) and intel openmpi. Files are read
properly with serial IO (when they are read by only master cpu) and produce
following error when using parallel IO. Same problem occurs with higher
versions of hdf5 (like 1.8.7, 1.8.8).
Any help will be appreciated.
Cheers

What kind of parallel environment are you in? this error looks like,
for example, you are in a parallel environment where files exist on
one system but not another.
What file name are you passing to your open call?
Which file access method are you using? MPI-IO or MPI-POSIX?

In addition, if you can, please provide the code, or at least a snip of the code that you use to access the file. That would help a lot to understand your problem.
Thanks,
