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
