Hi all, I built fenics on our cluster and got to the point where I can sometimes completely run the demo_hyperelasticity.py, but only once!
Here is the rundown: 1. In the python2.7/site-packages/dolfin directory I run: rm `find ./ -name '*.pyc'` -rf 2. In another terminal I run python demo_hyperelasticity.py and it works all the way through 3. In the same terminal I repeat the command exactly, and it immediately crashes: Fatal error in PMPI_Init_thread: Internal MPI error! >From that, it looks like it is in the python compilation of the pyc files that the problem lies. Has anyone seen this before? Possibly related: I still get the python:96004 terminated with signal 7 at PC=37f720c380 SP=7fff17027758. Backtrace: /lib64/libpthread.so.0(pthread_spin_lock+0x0)[0x37f720c380] ... error but it goes away if I just repeat the commands. It seems to come more often if I delete ~/.instant but I can't reliably reproduce it. Thanks, Mike
