I am trying connect 2 compute machines in HPC server to solve 1 job with RSM in Ansys; 1 workstation as Client machine( Window Server 2012 R2, HPC Pack 2012 R2), 1 workstation as Solver Manager and Compute server machine( Window 7). I have just submitted 1 job from client to solver and get the result succesfully but only solver machine solve the job when I don't declare these computers integrated in HPC server. Now, I want 2 machine to solve the project in same time, I declare these computers integrated in HPC server and test in RSM, I see the error like this pic above. What will I do next?
