Hi Paul

 

By "jump problem", do you mean this?

Either way, simply set the thread that is your time master to run on only a
single core, using SetThreadAffinityMask() (on Win32, of course - not sure
what the equivalent, if any, might be on Linux).

Yes, it's a hack, but at present, it's what we got. ;)

Subject: [Algorithms] Timing problems

 

I've just fallen foul of QPC not working correctly having just gone from a
single processor to a quad core.

 

I remember reading somewhere that multiple processors could cause problems
in the future, but I guess the future (for me) just arrived. I do handle the
well-known "jump" problem but I guess that's old news now anyway.

 

Can anyone point me in the right direction for how to fix this please ?
