In case anyone here is also interested in supporting other climate related projects, WCG just announced that they are planning to restart ARP project again. https://www.worldcommunitygrid.org/about_us/article.s?articleId=811

They said "in the coming weeks".

That sounds like July at the earliest based on outcomes from their previous predictions. Then there's the system capability of handling all those large ARP files which brings everything to a crawl at WCG. I hope I'm wrong and things go smoothly, but since WCG has gone over to Krembil, anything much beyond MCM tasks have been a failure.

CPDN have been looking at incorporating the WRF model. It's similar to how WAH works. WCG implemented WRF in a peculiar way, by splitting timesteps if I understand correctly. Keeps tasks short but at the expense of moving alot more data around.

It might work out OK because they are planning to keep their data at Amazon Web Services (AWS), not on the servers they had been using.

It is true I am greatly disappointed at the gawd-awful support I have experienced at WCG since their move from IBM to Toronto. I am signed up to all five "current" WCG projects, but get only MCM1 tasks and sometimes not even those.

Yeah, WCG is more "miss" than "hit" lately. When it's running at all.
