Is anyone else having problems running on the Merlion cluster? #38

Closed AndrewEdmonds11 closed 9 years ago

AndrewEdmonds11 commented 9 years ago

I don't know who else uses the Merlin cluster to do runs but has anyone had problems with jobs crashing straightaway with the following kinds of error:

g4sim: error while loading shared libraries: libCint.so: cannot map zero-fill pages: Cannot allocate memory
g4sim: error while loading shared libraries: libstdc++.so.6: failed to map segment from shared object: Cannot allocate memory

It doesn't seem to be with specific runs and I don't think it's a problem with the code.

Any ideas?

I haven't run into this specific problem before. But if allocating memory is the important part, I'd check the memory statistics on your own computer. It might be similar to the problem we've run into before.

So looking at the output from hostname and ulimit -a it seems all the runs that crash straight away are on merlinc27 so I guess there's something woring with that node in particular.

I'll just run more jobs and hopefully it will get sorted.
