Why cannot to complete the parallel simulation without any error

Version:2020b

After starting parallel computing, antivirus software consumes a large amount of CPU resources, and parallel computing has been unable to complete the simulation (if the model is opened for direct simulation, it only takes 1 minute, and parallel computing still has no results after half an hour). It seems that the MATLAB process was intercepted by antivirus software

This phenomenon randomly occurs on different computers or model optimization updates.

Parallel simulation called 10 pools (computer CPU has 10 cores)

When the parallel simulation problem mentioned above occurs, the model simulation mode is accelerator, and there is no such problem when using normal mode

[Tom Yuan]

the model sim with accelerator has no problem. but when usage the parsim, the simulation cannot finished with antivirus software consumes a large amount of CPU resources

Hey Tom,

Could you let us know if the behavior still persists if you shut the security software off? Which Operating System are you working with?

[Tom Yuan]

hey ，thanks for your reply! If the security software is turned off, this problem will disappear on Win10 64bit

[Tom Yuan]

by the way, This security software belongs to the enterprise version under Qihoo 360

Hey Tom,

Since the issue disappears when the security software is turned off, it's pretty safe to assume the software is the cause of the issue. If possible, I'd look to see if there is a way to 'whitelist' or set an exception for MATLAB in the security rules.
