Re: namelist editing

Update: Doesn't seem possible to change by ems_domain --localize. But I edited ARWbdycntrl.pm PERL script to have it create new namelist files with the needed parameters (about line #110).

"When in doubt, read the PERL."

(But PERL is accused of being a write-only language...) :lol:

ifort or intel suite XE?

I was wondering if anyone knew what Robert used to compile uEMS - does he simply use intel fortran (IFORT), or the entire "parallel studio XE"? I also saw an intel MPI implementation, but I believe he does not use that - he appears to use MPICH2.

Thanks!

Re: Intel libraries

OK, I'm still using 19.4 - I haven't tried 19.5.
What was the output you received when you ran the recommended test (ldd wrfm_arw.exe.intel)?
Are you only running on a single machine? (specs?)
Can you post the contents of your /etc/hosts file?

namelist editing

Hello All: After creating/localizing a domain with dwiz, I need to edit part of the namelist.wrfm - the subsection with two values to be edited is: &bdy_control spec_bdy_width = 5 spec_zone = 1 relax_zone = 4 spec_exp = 0 specified = T nested = F / I edit it before starting with ems_run, but it reve...

Re: Intel libraries

Update on version 19 - the intel version of the WRF executable works well on one and two nodes of my cluster. I was unable so far to use more nodes. I use infiniband cards in the back of each node and simply string them together (no router) and that may be the problem, since there are several ports ...

Re: Intel libraries

Ah, I see - issues with Xeons maybe. No, wait, that isn't true - the INTEL exe ran perfectly on a single Xeon node with 12 processors while running the benchmark case. The only problem happened when trying to run across two or more nodes. I'll try again and try to report the error.

Re: Intel libraries

Update on this - I downloaded the latest version (19) and ran the benchmark case on a single machine and the intel compiled version worked fine. When I tried to run it across my (infiniband) cluster, then it failed with a segfault, although the PCI compiled version ran fine. I therefore suspect that...

Re: Intel libraries

They did not work for me. They passed the suggested test, also.

land use data

Hi All: I'm a little confused about the MODIS land-use data. I believe it goes like this: (1) the "Use MODIS data" checkbox in dwiz only initializes the domain land use categories (via MODIS data) (2) the ems_prep option --sfc sstsport |modis|ssthr (Appendix D9) also calls and incorporates diurnal s...
