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:

atp/1.7.3
cray-ga/5.1.0.5
cray-hdf5/1.8.13
cray-hdf5-parallel/1.8.13
cray-lgdb/2.3.1
cray-libsci/13.0.0
cray-mpich/7.0.0
cray-netcdf/4.3.2
cray-netcdf-hdf5parallel/4.3.2
cray-parallel-netcdf/1.4.1
craype/2.1.2
cray-petsc/3.4.4.0
cray-petsc-complex/3.4.4.0
cray-shmem/7.0.0
cray-tpsl/1.4.1
cray-trilinos/11.8.1.0
papi/5.3.1
perftools/6.2.0
perftools-lite/6.2.0
stat/2.1.0.1

cce/8.3.0
gcc/4.9.0

In addition, the following two modules were updated to be compatible with cray-mpich/7.0.0

fftw/3.3.4.0 (default)
fftw/2.1.5.7

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.

The CDT 1.16 release note can be found here,

The shared root file system is enabled by default

June 4, 2014 | 0 Comments

During today's maintenance, the shared root file system is enabled by default. You no longer need to explicitly set the environment variable, CRAY_ROOTFS, to DSL in your job scripts to run shared library applications on Edison compute nodes from now on. We do not expect any observable performance impact to the statically built applications, However, if you encounter any problems with this change, please report to consult at nersc dot gov. You can overwrite this system default by doing
