Following Running WRF-SFIRE with real data in the WRFx system

Initial setup

Following Atipa User Guide Phoenix

SSH

There was no .ssh directory in my account. Then passwordless ssh to compute nodes does not work contrary to the guide page 8. Of course commands over compute nodes such as fornodes -s “ps aux | grep user” also do not work.

Setting up ssh: 

ssh-keygen
cat id_rsa.pub >> authorized_keys

Passwordless ssh to head node works fine. Passwordless ssh to compute nodes was disabled for regular users intentionally.

Compilers

[jmandel@math-alderaan ~]$ gcc --version
gcc (GCC) 8.3.1 20191121 (Red Hat 8.3.1-5)
[jmandel@math-alderaan ~]$ ls -l /shared
drwxr-xr-x. 3 root root 17 Mar  5 20:21 aocl-linux-gcc-2.2-5

So gcc is at 8.3.1 and there is no other compiler on the system. Openmpi seems compiled with gcc 9 though:
