Timeline and Updates
January 16, 2015
Edison compute node memory was upgraded to 1866 MHz from 1600 MHz during the maintenance on Jan 13-16, 2015. Edison now has a 14% improved memory bandwidth, and we have seen a 2-9% of performance increase with the standard NERSC 6 application benchmarks. We expect that the increased memory bandwidth will improve your application performance as well.

September 28, 2014
The Cray Developer Toolkit (CDT) 1.19 was set to default during the 9/25/14 maintenance. The following software versions are now default on Edison
June 26, 2014
The Cray Developer Toolkit (CDT) 1.16 was set to default during the 6/25/14 maintenance. The following software versions are now default on Edison:
In addition, the following two modules were updated to be compatible with cray-mpich/7.0.0
Note, an ABI (see https://www.mpich.org/abi/ for more information) change in the Cray Message Passing Toolkit 7.0 release (cray-mpich/7.0.0) requires all MPI user code to be recompiled. Scientific libraries, Performance Tools, Cray Compiling Environment and third party libraries compatible with the new ABI are included in CDT 1.16 release.
