[Workshop-all] traXXX acounts on loging nodes

Hello all,

I very happy to see that the training accounts are still being used for experiments (they are good until about August 15th and you are welcome to use them until then),

Unfortunately I have also received emails about too high CPU load and some of you may have seen their processed "killed" by the OS. This happens because I had forgotten to include

export OMP_NUM_THREADS=1 ./exe/cactus_etk_workshop par/static_tov.par

without the OMP_NUM_THREADS the process tries to start 64 threads which is as many as there are cores which can cause it to stall.

Yours, Roland
