I implemented a simulated annealing, where in the inner cycle I solve many 
transportation problems with glpk.

Then I parallelized it with MPI, and got great results almost linear speedup.

Now I parallelized it with a distributed shared system, not using threads, and 
somehow glpk its messing with the virtual memory of the DSM system, because 
when I use the virtual memory the implementation sometimes dies with 
segmentation fault, I said sometimes, because sometimes ends OK.

The DSM system I'm using is page based, and it uses threads to manage the page
