Sometimes it hungs at SIMPLEX, but I guess because the data given to it its 
not the correct, somehow glpk is writing on the address space of the DSM 
system.
I know that glpk is not re-entrant. What I do is each node solve a different 
transportation problem, each computer runs its own glpk problem, the data is 
divided in parallel, but glpk is runned sequentaly.
