We installed ABAQUS on one of our clusters, and the server has two nodes, each having one Dual-core CPU and 2GB RAM. When we log on to the system, we are on the head node which is the default one. To change the node, we write "ssh compute-0-nodeNumber", but when we change the computing node, we don't have access to ABAQUS files anymore, because when I log on to the a computing node (e.g. "ssh compute 0-1"), ABAQUS path is not defined in PATH variable, and neither can I find it on the specified path which is seen from the head node (/opt/ABAQUS/etc...). How can I access that path and what is the best way to use those nodes to run a job?
