I was wondering if CHARM needs to be built with CUDA option for NAMD
(with --with-cuda option) to make use of GPUs.
I compiled NAMD 2.7b1 like following:
Built Charm 6.1.2 as below:
/build charm++ multicore-linux64
Built NAMD as below:
/config Linux-x86_64 --with-cuda --charm-arch multicore-linux64
But the test apoa1 code runs slower using GPU than using the CPU
itself. Just wanted to know what the reason could be.
