NAMD crashes with LES option ON

Hi,

I am trying to use NAMD version 2.5b Origin-MPI to run LES (locally
enchanced sampling). But jobs stops with MPI error pasted below.
On turning off LES option NAMD works ok.

Even NAMD Origin-2000 single processor works fine with LES option on.

But I would like to use more than one processor since its a huge system
and single processor will take ages to complete. So the question is
is LES option supported on multiple processors? If yes is it only SGI
version that is not working?

Please I will appreciate any help on this.

Please also let me know if you need me to send some files for testing.

many thanks
Karunesh
