Hi Leandro / all,

thanks for the quick answer. I tried the binary NAMD_2.5_Linux-i686-TCP, but
now I get the following error message:

Charmrun: error on request socket--
Socket closed before recv.

I found the same error message in the Charm++ FAQ:

Charmrun: error on request socket--
Socket closed before recv.
This means that the node program died without informing charmrun about it,
which typically means a segmentation fault while in the interrupt handler or
other critical communications code. This indicates severe corruption in
Charm++'s data structures, which is likely the result of a heap corruption
bug in your program. Re-linking with "-memory paranoid" may clarify the true

So I tried to compile NAMD/Charm to solve the error above ?
Do you have any suggestions ?
