Remote connection to ncm0394 could not be started, or exited with return code 255
Hello all, I received this following new error. Apparently the run was using a host, which was specified in $CFXHOSTS, which i have no access to. It is the first time i encountered this error, but i have been using RWTH cluster for calculations only for the past few weeks. Did something change recently in $CFXHOSTS, or is $CFXHOSTS not yet updated for the new machines?

Hi Marek, this is normal, as no one has access to the compute nodes per ssh per default. But CFX is in desperate need of ssh for multinode jobs. We are working on this issue. With LSF we were able to write a wrapper for ssh using blaunch. We were not successful up to now with srun. So we will have to find another way. For the time being, you will be bound to single node jobs with CFX. Best Marcus On 2/27/19 1:32 PM, simon@isf.rwth-aachen.de wrote:
