Re: Compile NAMD on Bluegene

This Blue Gene machine is located at Boston
University. As far as I know, NAMD is not installed.
Since NAMD requires single precision fftw to do the
PME calculation and I found the preinstalled fftw with
the machine has this version, I will use that fftw
first. It it failed again, I will try to compile it as
Gengbin suggested.
I have another question as mentioned in previous post,
ie, what BL_HOME variable should I define to be able
to use charm++?
