Ok, so it seems a problem with parallel access to this file system. Other network file systems like NFS, for instance, should not be a problem, right?
Do you know if there is some method just for checking that this kind of problems will not arise in a particular system (with an 'unknown' file system)?
you can use NFS if you must but NFS is also not a true parallel file system. One could simply write to a local file system for a start. The PVFS parallel file system is another option. It's free and easy to deploy. Many sites have Lustre, though it is a bit more complicated. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
