Re: Intel® Hyper-Threading Technology conflicts with LabVIEW utilities (VISA, Scope GUI, IO Trace...)

Hi,

 

I was struggling for quite a long time with a large application that exhibited the following problems:

 

- The application stalls unpredictably after some time, sometimes a minute, sometimes hours. After clicking into the GUI it starts working again. This repeats in an unpredictable way. Competitive activities on the computer seemed to increase the stalling-frequency.

- Sound Input VI stops unpredictably and has to be restarted.

 

I really was considering to give up LV and turn to conventional programming.

 

For the moment it looks like disabling Hyperthreading in the BIOS cures the issue. It is a modern ASUS workstation board with 4-core i7 CPU runing under Win7 64 bit and LV2012.

I hope this is a permanent cure. I don't benefit from Hyperthreading because my applications are massively floating point dominated.

 

If the issue comes back I will be reporting here.

 

Cheers

Edgar
