Thanks for that information. Could be a life-saver! However, please note that I checked with a local expert and he says, "if you want any optimization on the compute nodes you should use the cross compilers. Likewise, if you use optimization on your frontend compile, you won't be able to run on the compute nodes. They're not fully binary compatible and they do not use the same OS. So your mileage will vary with this approach.”

If you use the MPI wrappers (I don’t), then all will be taken care of. I don’t think that I have compiled pv+catalyst to run on BGQ, so my comment is only based on theory, but I can set a build going in a minute if it helps (except I’d need to setup mesa which may take a while, so maybe I won’t....)
