Dear Dr. Hein,

 I forgot to mention that we have managed compiled namd2.5 for p690. We
had to edit <namdsrcdir>/charm/src/conv-core/isomalloc.c and just
comment out or remove following lines:

-------------------------------------------
       if (retval==(-1))
       CmiAbort("munmap call failed to deallocate requested memory.\n");
-------------------------------------------

Compile charm with

./build charm++ mpi-sp -O -DCMK_OPTIMIZE

and build namd with

./config tcl fftw plugins IBM-SP

 Also, thank you for your suggestions and your offer to keep me posted
on the progress, that would be great.
