Hello NAMD users,
I need to have a NAMD executable that can run on 16cpus of 1 node on Ranger without using the MPI environment. Can anyone tell me about the optimal build options for Ranger?
I have tried to compile using the following options:
build charm++ net-linux-amd64 -O -DCMK_OPTIMIZE=1
config tcl fftw Linux-amd64-g++
I have used the fftw-linux-amd64 and tcl-linux-amd64 libraries from the NAMD home.
But, the compiled version is several times slower than the executable from the directory ~tg455591/Linux-amd64-MVAPICH-icc/namd2.
Any suggesstion that will help me to compile and get close to the optimal timing would be greatly helpful.
