I have install the c37a2 charmm with parallelization，and it shows that success,the installation commands is:
./install.com gun xxlarge M
However,when I submit a job, I found the rate is so slow! Even slower than the non-parallelization charmm with just only one CPU!
Besides,I submit the job to the cluster with qsub.and I just use just one node and each node has 8 CPUs.
