[Imstk-developers] high-speed thread in iMSTK

[Zhaohui Xia]

Hi Andinet,

 

I am afraid I made a mistake. The device thread is definitely a high-speed thread. I figure out the issue, because I forget to close something when I change the code in that thread.

 

I think there is no performance bottlenecks currently in the main thread under Release mode (60-70HZ), since the mesh size (1000 vertices) is not very big now.

But under Debug mode, the speed is too slow, it is just 0.16HZ for the same mesh. Do we have any ways to improve it, e.g. changing some settings? It would be very helpful for work if it can run faster.

 

Thanks,

Zhaohui

Can you profile your code and let us know the key performance bottlenecks in iMSTK?

 

This is something Dr. Des is also interested. We will be exploring ways of accelerating some of the modules.

 

thanks

Hi All,

 

Do we have a high-speed thread (e.g. 1000HZ) in iMSTK? I tried different modules e.g VRPNDeviceServer (device) and SceneMange (main thread), but the maximum frame rates of them are 60-70HZ under Release mode.

I also tried to set the Loopdelay to 0.001 or smaller (from my understand, its default value is 0 should have the fastest speed, but it also 60-70HZ).

 

Thanks,

Zhaohui
