Application warning:Execution required more than a sample block duration

Post by lijing » 28 Oct 2021, 22:03

After using the new version of bci2000, this warning appears in bci2000.
Application warning, ***Task: ***Task::Process: Execution required more than a sample block duration.
Does it matter?

It matters if it keeps repeating constantly. If it appears only intermittently, e.g. at start/resume, it is a hint that you should look at how your application module spends time in StartRun(). Make sure that any CPU intensive initialization is done during your application's Initialize() function rather than StartRun(), if possible.

Thank you for your reply. It only appears once at the beginning of running, and we have put the CPU intensive initialization code into the initialize() function.
