[FLASH-USERS] maximum number of cores ever used to run FLASH?

[Ricker, Paul Milton]

We can't beat Sean, but here's MHD+N-body cosmology weak scaling on jaguar with 16^3 blocks up to about 100k cores.

Well that's about 2 orders of magnitude larger than what I've used. I'm going to guess no, no one can beat half a million cores.

For fun, let’s play throwdown.  Can anybody beat 525k cores (2 million threads of execution)?  See attached (1 Mira node = 16 cores).

Dear FLASH Users/Developers,

Does anybody know the maximum number of cores that FLASH has ever been run successfully with? Any reference for this? I need the information for a computing proposal.

Thanks!

Rodrigo
