[FLASH-USERS] Weak scaling vs Strong scaling of FLASH benchmark?

[Anshu Dubey]

Dear Fei,

If you only change the number of MPI processes, the code operates in strong
scaling mode. If you wish to do weak scaling studies you have to change the
problem size by hand. We can give you ideas on how to do weak scaling if you
are interested.
