Hi all, I am trying to run the step-32 example program on a cluster using deal.ii 7.1.0 and Trilinos 10.4.2. It runs fine (if quite slowly) on a single processor, but if I try to give it more processes, it hangs for all intents and purposes (the vast majority of the time being spent in the BoussinesqFlowProblem::solve() step). I believe that the problem comes down to something spawning way too many threads on the compute nodes, which are then interfering with each other. I am not sure why this is the case, as I have deal.ii compiled with --disable-threads. Is it possible that these are being spawned by the Trilinos libs? Any insight would be appreciated. Thanks, Ian Rose
