I am trying to connect my MATLAB to a university cluster, to submit parallel simulations to its Slurm scheduler.
While validating the cluster profil, the process is already teminated when trying to create the connection to the cluster running clusterAccess.connect() inside of RemoteClusterAccess.m
MATALB is showing me the error message below. Stating that a leasable connection can't be created, because the Algorithm negotiation has failed:
This way I can try to set the connection with the Ganymed-SSH2 javalib. Again the process is terminated when creating the connection, here running ssh2_struct.connection.connect() fails. The commannd window states this:
In general, connecting to the cluster using PuTTY works fine. In PuTTY I also found some settings regarding Algorithms.
My thought understanding the problem is, that I need to change connection settings in MATALB or inside the Java class so the connection Algorithms fit the cluster. But I am not sure if it is the right approach and where to do so.
The cluster is running on Linux while my MATLAB is running on Windows, would it be helpful to try to connect from MATLAB running on a Linux system?
Does someone has another idea what could cause the problem or what I can try out?
