If your configure script fails with compiler checking
April 29, 2014
We are in the process of getting a permanent fix for this issue, and we load craype-ivybridge modue on Edison login nodes now. Your configure script may fail again. If you see this, please use the two workarounds we provided below until we get a workaround or a permanent fix. 06/05/2014
This problem was fixed as of 4:00 pm PST 5/1/2014 by providing a temporary workaround. (We load the craype-sandybridge module instead of craype-ivybridge module by default now.)
If you compile your code using Intel compilers, your configure script may fail with compiler checking because the compiler wrappers from craype/2.1.1 generate the binaries that do not run on login nodes. We have filed a bug about this with Cray. The temprary workarounds are:
1) do "module unload craype-ivybridge" or "module swap craype-ivybridge craype-sandybridge". then after configure is done, reload the craype-ivybridge module or swap back to craype-ivybridge module.
2) you can unset the environment variable, CRAY_CPU_TARGET to run configure, and reset it back to ivybridge after configure completes.
unset CRAY_CPU_TARGET #for bash
unsetenv CRAY_CPU_TARGET #for csh
after configure is done, before compiling (before running make commands) do
export CRAY_CPU_TARGET=ivybridge #for bash
setenv CRAY_CPU_TARGET ivybridge #for csh
