Hi,
I am running the tutorial "One-dimensionalumbrellareplica-exchange sampling". I have followed the steps mentioned in the tutorial:
cd umbrella-sampling
mkdir output; cd output
mkdir {0..15}; cd ..
cbme_at_cbme:~$ mpirun --version
mpirun (Open MPI) 1.6.5
The job0.conf file is as follows:
source stretch_alanin.conf
# prevent VMD from reading umbrella.namd by trying command only NAMD has
if { ! [catch numPes] } { source ../usr/local/lib/replica/umbrella/umbrella.namd }
After running the following command:
mpirun -np 16 namd2 +replicas 16 job0.conf +stdout output/%d/job0.%d.log
ERROR appears:
cbme_at_cbme:~/Desktop/replica/umbrella_1d/umbrella_1d$ mpirun -np 16 namd2 +replicas 16 job0.conf _stdout output/%d/job0.%d.log

--------------------------------------------------------------------------
mpirun noticed that process rank 15 with PID 2979 on node cbme exited on signal 11 (Segmentation fault).
Computer specification:
Memory: 32gb
Processor: intel@ Core i7-3770 CPU @ 3.40Hz x 8
Graphics: Gallium 0.4 llvmpipe (LLVM 3.5, 256 bits)
OS type: 64-bit
Disk: 3 TB
After this step their is nothing appears, could anyone please help me where is the problem. I am running MPI on single computer. I think I am not able to connect the mpi with the tutorial path.
