並列化時のオプションとしてsmparとdmparというのがあるようだ。

`3. Build WRF

If we use smpar option, then there is no need to call mpich to run WRF in parallel. Instead, we just need (for real case):
wrf.exe >& log.wrf.txt &

...
Things are a little different with dmpar. With this option, we can run wrf.exe by using:
mpirun -np 8 wrf.exe >& log.wrf.txt &

dmparとsmparの違いについては以下のQ7にも記載がある。

SMPar is for multi-core/multi CPUs,
...
DMPar means "Distributed-memory Parallelism," which means MPI will be used in the build.

OpenMPについて記載されているが、MPICHだとどうなのかは今後調べる。
