[Wrf-users] Max number of CPUs for WRF

[Don Morton]

Hi, 2,048 is no problem.  I invite you to look at our benchmarking page

http://weather.arsc.edu/WRFBenchmarking/

for some test cases, and we'd enjoy getting your results.

I've used 10,000 cores, and at the level, the limitation is that the rsl.*
files only have four digits for the task number, so you need to go into the
code and change that.

Cheers,

Don Morton
