I bring you a riddle here to help me solve.
I am trying to run a 100000 simulation but NAMD 2.9 quits early.
My configuration file requests
but the last line of the output to the log file states
WRITING COORDINATES TO DCD FILE AT STEP 67000
The velocities and coordinate files did not get written. It is clearly an
unwanted early termination. No error message.
The head of the log file says
Charm++: standalone mode (not using charmrun)
Converse/Charm++ Commit ID: v6.4.0-beta1-0-g5776d21
CharmLB> Load balancer assumes all CPUs are same.
Charm++> Running on 1 unique compute nodes (32-way SMP).
Charm++> cpu topology info is gathered in 0.094 seconds.
Info: NAMD 2.9 for Linux-x86_64-multicore

Info: 1 NAMD 2.9 Linux-x86_64-multicore 32 inca igregore
Info: Running on 32 processors, 1 nodes, 1 physical nodes.
Info: CPU topology information available.
Info: Charm++/Converse parallel runtime startup completed at 0.169809 s
Info: 2265.71 MB of memory in use based on /proc/self/stat
I am running this on a 32 core Linux 64 machine with 256GB RAM. Notice that
this is NAMD 2.9 release.
Has anybody seen anything like this?
