Funding to maintain WRF-NMM has ended and support will no longer be provided. http://www.dtcenter.org/wrf-nmm/users/
It was already in the air for a while, now i hope NEMS-NMMB comes from the development phase to full implementation in Linux environments...

Hi jackq7a, with or without nesting ?

Hi did some quick test :

1) HT off (BIOS): 10 min 4 sec
2) HT on 4 thread : 10 min 8 sec
3) HT on 6 thread : 10 min 44 sec
4) HT on 7 thread : 10 min 46 sec

The solutions number 1 and 2 are identical for performance, 3-4 are 6% slower.

Htop show 4 cores working at 100% (wrfm_arw.exe) and 4 cores at 5-45% (depending on what i use in the operating system)
