Subject: Re: [Pytom-mail] mpirun problem Hi Haixin, This is a known problem with MPI and pytom dynamically linked libraries. It is mentioned in the pytom FAQ: http://pytom.org/doc/pytom/faq.html PyTom: Tutorial<http://pytom.org/doc/pytom/faq.html> pytom.org Answer This is due to a old swig version ( 1.3.40). Please install a newer version and rerun the PyTom installation. ... You need to have the LD_PRELOAD variable set in you shell: BASH: export LD_PRELOAD='/usr/local/openmpi/lib/libmpi.so' CSH: setenv LD_PRELOAD '/usr/local/openmpi/lib/libmpi.so' -- Hope this helps, Dustin Morado John Briggs Group MRC LMB ___ Cheers, Dustin M.

The "localization.py can now be successfully executed with the job.xml without using mpirun. If not working with parallel computing, the "localization.py" runs too slow to be practically useful. However, I failed to make the "localization.py" run with openmpi! I am not sure if this is a problem with the openmpi environment we have or not. I tested the openmpi on both my work station and my laptop using two simple testing programs provided by openmpi distribution package. The test programs worked well on both. However, when I did mpirun with localization.py, I got the same error message on both of the two computers.The error message has been included in this email. Any ideas about what went wrong? Thanks for your help in advance !
