The compilation was successful. Running a simple test calculation (close-shell CCSD(T) with a large basis set), we found the parallel scaling stopped (especially the time for the election integral) when requesting with more than 4 cpus. The mpich2 was compiled with icc/ifort, and the communication device is ch3:nemesis. Any suggestion?</div><div><br></div><div>Thank you!</div><div><br></div><div>Best
