If your codes hang or run much slower after the maintenance on 6/25/14

June 27, 2014 | 0 Comments

During the maintenance on 6/25/14, Edison was upgraded to Cray Linux Environment (CLE) 5.2UP01 and Cray Message Passing Toolkits 7.0.0 which require all MPI codes to be recompiled. As a result, some users may see their codes hang or run much slower than before after recompilation. We believe this is due to some regression introduced in the new CLE version, and have filed a bug with Cray. If you find your codes run much slower than before,  please use one of the two workarounds below until Cray provides a permanent fix.
