Dear NAMD users,

I'm trying to run NAMD in a HPCC that i have access which has multiple nodes connected by OFED, possible usage of CUDA, support for MPI.
I'm having difficulties to use NAMD in the server.
I've tried different versions of pre-compiled NAMD, by basically downloading and untar'ing them but i got the following error messages.

Error messages with multicore-CUDA
/scratch/xxx/NAMD_2.13b1_Linux-x86_64-multicore-CUDA/charmrun: line 34: /scratch/xxx/xxx/xxx/charmlist: Permission denied
/scratch/xxx/NAMD_2.13b1_Linux-x86_64-multicore-CUDA/charmrun: line 34: exec: /scratch/xxx/xxx/xxx/charmlist: cannot execute: Permission denied

Error message of ibverbs
Charmrun> charmrun started...
Charmrun> mpiexec started
Charmrun> node programs all started
Charmrun> node programs all connected
------------- Processor 9 Exiting: Called CmiAbort ------------
Reason:

                Length mismatch!!

I already found some information on the web that they were saying the “length mismatch” error means you are not using the correct version.
Which version should i use?

Thanks a lot for your help. Please find the sh script below.
