ems_run stops at initial and boundary conditions

Hi there,
as stated in viewtopic.php?f=8&t=16&start=160
we now afforded a brand new work station to run simulations with wrfems.
2x10 cores and 256GB RAM. OS is openSUSE.
After installation I tried to run two different benchmark tests, they both stopped at the same point after starting the run: where wrf tries to create the initial and boundary files. In that moment the performance of the systems goes down to 0% (solely kernel operation). Same thing if I try to run a domain created with the domwiz. I don't even get an error message. )-:
Ems_prep works fine, though data is grabbed from a USB hard disk, since a Linux OS is not allowed in our windows based house net. So I had to give the domain directory a symlink to the external hdd which we would fill up frequently. Afterwards the wpsprd is full of NetCDF files.
Any peculiarities apart from that are unknown by me. Installation worked fine with the install.pl using something like a bypass connection into our house.
Did I forget to install anything else (java,..)?

Do you have an entry in your hosts file for your machine name and IP address?

No, I didn't. Thanks for the suggestion. I just added the machine name (Linux-kfo9.site) with 127.0.0.1.
Still doesn't work... >In fact no notable changes

Hi again,
I just noticed that although EMS.profile says that there are 2 times 10 CPU (which meets the hardware I ordered), YaST tells me different with a total number of 40 cores. Hmmm?!?

Anything useful in wrfems/runs/<domainname>/logs after hanging?

Thanks meteoadriatic.
in the run_real.log file I find the note ssh: Could not resolve hostname Linux-kfo9: Name or service not known

Obviously I added the wrong machine name with Linux-kfo9.site
It's running know and it looks perfectly normal so far.
Thanks a lot!

Yes, logs directory is always first place to look when something goes wrong :)
