You can check either the server configuration file or the calculation script that you plan to use to see if parallel calculation is enabled.
To check whether parallel calculation has been enabled in the server configuration file:
Search for the parameter CALCPARALLEL, and check its specified value.
The number of threads that can simultaneously perform tasks to complete a calculation is specified by a value between 1 and 128. Block storage databases running on 32-bit platforms support up to 64 threads. Block storage databases running on 64-bit platforms and aggregate storage databases (whether running on 32-bit or 64-bit platforms) support up to 128 threads.
