To compile with the intel compilers load the intel module and any other modules you need. For example:

   module add intel mkl fftw
   icc ...

We now have a license for intel mpi but there's also an intel compiled openmpi installed:

   module add intel mkl openmpi_eth

To configure XMDS2 to use the intel compiler:

   module add intel fftw mkl openmpi_eth
   CXX=icc xmds2 --reconfigure
   xmds2  ...

XMDS2 might not generate the correct linker command for intel, so if you get a linker error try adding -ldl at the appropriate place in the Makefile:

   ... -L/usr/lib64 -lz -lm -ldl -Wl,-Bstatic

The login node is running on an FC430 which is the newest hardware so if your code is compiled with -march=native it will get that error if you run it on older hardware. There are four possible solutions:

• Compile your code with -mtune=generic instead and it will be runnable on all nodes.
• Submit your job to the FC430 nodes it was compiled for with #SBATCH --constraint=FC430 in your submission script.
• Compile your code on the hardware you plan to run it on. For example if you plan to run it on the C6220 and C8220 nodes start an interactive job with --constraint='[C6220,C8220]' and compile your code there.
• Compile your code on the oldest hardware which currently is F720, C6220 and C8220: start an interactive job with --constraint='[C6220,C8220,R720]' and compile your code there.
