This morning I was attempting to get WRF 2.2 to build with 6.2.5 PGF on Linux 86_64 (rocks 3) without sucess. I was attempting compile option #3
- PC Linux x86_64 (IA64 and Opteron), PGI 5.2 or higher DM-Parallel (RSL_LITE, MPICH, Allows nesting, No periodic LBCs)
and the compiler would get killed by the OS for eating all system memory (2 GB physical). After setting up memory limits, I would get this error.
Subprogram too large to compile at this optimization level (solve_em.f90)
So I was able to get it to compile by removing -fastsse, but was curious if anybody had comments on this.
