Running CST Studio on Linux

A same version of CST running on Windows is required.
Only Time Domain Solver and Frequency Domain Solver have been tested successfully.

1 Add the rsa key authorization to Linux

CST needs an rsa key to log in to the Linux host.

If you don’t have that, generate one on Windows with puttygen.exe and copy the public key to ~/.ssh/authorized_keys.

Then on Linux,

$ echo "StrictHostKeyChecking no" >> ~/.ssh/config

2 Setup CST on Windows

2.1 Set “hosts” file

Run cmd as admin, then type

notepad c:\windows\system32\drivers\etc\hosts

Add

linux_ip_address linux_host_name

to this file and save it.

Run putty.exe in the “CST STUDIO SUITE 2019” folder. Enter the linux_host_name mentioned above and click Open. You will see a dialog and choose “yes”.

2.2 Set mpi in CST

Setup Solver → Acceleration → MPI Properties
Set CPU acceleration up to to 1; Check MPI
In MPI Properties, set as follows:

cst2

You need to set the user, host and Temp Folder(“mkdir” first) as your own.

Export settings for the next load.

That’s all done! Click Cluster Test. You should see something like this:
