Once it’s ready, log into the new ParallelCluster:
pcluster ssh wrfcluster -i ~/.ssh/lab-3-key
The EC2 instance asks for confirmation of the ssh login the first time you log onto the instance. Answer with “yes”.
pcluster ssh is a wrapper around SSH. You can also log into your head-node using ssh and the public or private IP address depending on the case.
If you have forgotten the unique cluster name, it can be retrieved with:
$ pcluster list
Once inside the ls command will reveal files added by the post_install script:
[ec2-user@ip-172-31-40-92 ~]$ ls Desktop FEFFruns JFEFF JFEFF.desktop jfeff_examples
And the WRF runtime environment provided by the EBS disk image:
[ec2-user@ip-172-31-40-92 ~]$ ls /shared bin jasper-1.900.1 netcdf-4.1.3 WPS_GEOG WRFV3.7-mpi-openmp feff9 libpng netcdf-4.4.1 wrf zlib fftw libpng-1.2.50 packages WRF-benchmarks zlib-1.2.7 fftw-3.3.4 libpng-1.6.23 wps WRFV3.7 zlib-1.2.8 jasper netcdf WPS-3.7 WRFV3.7-mpi
All of this will be visible to the compute nodes:
[ec2-user@ip-172-31-28-77 ~]$ showmount -e Export list for ip-172-31-28-77: /opt/sge 172.31.0.0/16 /opt/intel 172.31.0.0/16 /home 172.31.0.0/16 /shared 172.31.0.0/16
