LV and multi-core

[salvai.m]

Hi guys,

in my program I acquire continous data with PXI-4472 and DAQmx (fs:40960Hz, 4096 samples).

I run this on two PC, one dual-core, the other one-core.

Sometimes on the dual-core PC, the acquisition seems "paused" and it "restart" after 5sec but the buffer could go on overflow. In these 5 sec on the task manager I saw one of the two core works at the 100%.

On the other PC one-core the program always works fine.

(I've got this problem also on a notebook dual-core with a 4472 Simulated device)

Someone of you got also this problem ??? and better someone can help me ?

Thanks a lot !!!

Michele

I haven't had problems like this, but you can try setting the process (from the Windows task manager) to run only on a single core to see if this is really the source of the problem, but you should note that this change needs to be made manually each time.

One other option is changing the priority or the execution systems of the DAQ VIs (in File>VI Properties>Execution) to the DAQ thread.
