+++++++++++++++++++++++++++++++++++++++++++++++++++++++ Dear Wien2k user, I was wondering why CPU usage in my machine oscillates around 200 in lapw1&2, although, The "OMP_NUM_THREADS" equals to 1 in my .bashrc (export OMP_NUM_THREADS=1)? P.S."setenv USE_REMOTE 0" in the parallel_options. Cheers, Salman ++++++++++++++++++++++++++++++++++++++++++++++++++++++++
