#31 fixed UMUI: how to submit to HPCx jeff michael.bane@…

Regarding the UMUI running on a local machine for submitting PUM jobs to HPCx, it is unclear from pages

whether the UMUI downloaded from the latter can submit directly to HPCx (and if so whether any extra steps need to be taken, such as a local:$HOME/.umrc or a remote:$HOME/.rhosts) or whether a umsubmit script has to be run from the user's local machine

#33 fixed Timesteps in vn6.1 um_model caroline@…


Simple question - what is the timestep for the operational global model vn6.1? Is it still 20 minutes? I'm not sure where to look in the UMUI to find out.

Best Wishes, Caroline

#34 fixed A limited area UM - GCR failing to converge cwang g.n.petersen@…

I'm trying out a new domain for limited area runs. My domain cuts off over Greenland at about 75N, i.e. northward of the highest point. I am aware that there might be some problems related to the domain cutting so close to a high topography but I am trying to get away with as small a domain as possible.

I've run the domain for 48 hours from 2007022100.T+0, successfully it seems. However, I do notice that the print out, the .leave-file, it sometimes state that GCR(2) didn't converge in 100 iterations (see example below). Is this something I should worry about? Is there any other signs that would indicate that my domain is not going to be stable?
