Thanks!</p> <p>We are not able to get any additional info from the user code or fortran lib. But we have intel compiler ticket with regards to this issue, number 6000089383. We would like for you to engage your compiler developers to help provide additional info about the specifics of the error. </p> <p>Thanks, I will contact them for it.</p> <p>could you please copy the affected file <span class="error">&#91;0x20009c845:0x14ddf:0x0&#93;</span> out of Lustre and check with the application to see<br/> whether the problem disappeared or not? Thanks!</p> <p>Key here is that it is not always the same file and the error doesn't happen every time on the same file. But I will try to see if I can reproduce it on a different filesystem.</p> <p>Hi Mahmoud,</p> <p>could you please use the "GETLASTERROR" call mentioned in 6000089383 to get the actual error returned by OS? Thanks!</p> <p>Hello Mahmoud,</p> <p>Do you need any more Lustre related work done on this ticket?</p> <p>If not then I would like to close it.</p> <p>Thanks,<br/> ~ jfc.</p> <p>This can be closed as we have <a href="https://jira.whamcloud.com/browse/LU-6545" title="MPIIO short reads" class="issue-link" data-issue-key="LU-6545"><del>LU-6545</del></a> opened.</p> <p>Thanks Mahmoud.<br/> ~ jfc.</p> Development Rank 1|hzx7wv: Rank (Obsolete) 17768 Severity
