Re: NAMD attempting to read FFTW

This file is normally generated once and only once for each MD simulation
of the same system. If it can't read the file it will eventually timeout
and create one. The file contains optimizations/parameters for the
fourier transform code FFTW that can be reused if namd is called to run on
the same system.

Can you give us some details about the machine your running on, the
operating system, version of NAMD2.5, etc...
