I probably just need to ensure lustre picked up all changes from common code. Can you confirm your code works if you prefix the filename with "ufs:" ? ==rob -- sent from a phone From: Sean Delaney <[email protected]> Sent: Oct 29, 2014 9:54 AM To: [email protected] Cc: Latham, Robert J. Subject: RE: discuss Digest, Vol 24, Issue 35 Hi Rob, Yes, this is mpich-3.1.3, as downloaded from the website in the last 2 days. I was alerted to the buf_idx[] overflow by a failing assert statement, which checks for overflow when assigning values to buf_idx[]. I'm running on lustre. I can't provide my current code as a test case. I may be able to prepare something later, but I need to focus on making my code work first. These variables have type 'int', whereas something like 'size_t' or 'ADIO_Offset' might be more appropriate to store buffer offsets, where constraints are not known. Sean ----------------------- this is in the latest 3.1.3 MPICH? I thought I bumped up the size of buf_idx and related fields, though my test cases are meager at best. Do you have a test case? Which file system? ==rob ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
