#1579: GRHydro does not build on Blue Gene/Q ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: development version Keywords: | ----------------------+----------------------------------------------------- Some of the C++ source files in GRHydro do not build on a Blue Gene/Q with IBM's compiler. The problem is that the compiler takes a very long time (>8h) even without (sic!) optimization. "The usual" playing with compiler options or changes to the source files had no effect.
I consider this to be a bug in the compiler. A work-around may be to switch to Clang as C++ compiler.

Is it known whether gcc works?

No, but I don't have any indications that either gcc or clang would have problems. Clang is preferred, since it supports the BGQ vector instructions much better.

Is this still an issue with the current code in GRHydro? Do we still have access to a blue gene/q system?

I have not tested on BGQ recently, but I just renewed my ANL account where I have access to a BQQ.
