Hi.

I am trying to solve a large problem in parallel using asynchronous solver sessions. However, I get this error as soon as I start the simulation ‘The number of simultaneous solves by solver 'CPLEX' exceeds the license limit of 1.' I have CPLEX (Full) solver in AIMMS. Is this because I have a personal node locked AIMMS business license? How do I check the number of solver sessions that I can run simultaneously in AIMMS? Is there a way to activate the Parallel CPLEX option? Thanks.

Hello @Suj8epri , looks like your license does not support multiple solver sessions. 

 

See Solve in parallel with Asynchronous Solver Sessions — AIMMS How-To

 

If your license does not show a number like in the below screenshot, then you can only run one session at a time.

Dear @Suj8epri 

Just to be clear; you can request an upgrade (for a fee per extra session) of your license by sending an email to info@aimms.com.
