Re: How to force thread affinity for MFC app?

I've used Matrox and API for years in multiprocessors without any crashes due to the
graphics card driver. But I've never heard anything good about NVIDIA cards in the last
two years. The fact that a graphics card can't work in a multiprocessor environment is a
serious condemnation of the competence of the programmers who wrote it. Multiprocessors
have been around for ten years or more.

I would love to know a video card vendor that ships bug-free drivers. They
all gave me grief... ATI, Matrox, NVidia, Intel. Diamond (S3) worked,
though, but I haven't used them since Win95.

Yes, NVIDIA seems to have inherited the "Diamond mantle" of creating
really unreliable
display drivers...I don't have an NVIDIA card, but I know people who are
getting rid of
them because they can't get working drivers. And I would never own one,
just like I never
owned a Diamond card. NVIDIA should look at what happened to Diamond as
an object lesson.

Even if OpenMP creates multiple threads at startup, these threads would
not be doing any
graphics until long after your InitInstance handler, if at all. They
would actually be a
thread pool that was idle until you did an OpenMP operation. I'm still
trying to figure
out all the OpenMP details myself.

Send me email and I'll send you a copy of my Affinity Explorer, which I
don't seem to have
put up on my Web site (I thought I had...oh well, another project to
finish...)

I use OpenMP on much of my app. But the relevent issue that I'm debugging
is
a known issue caused by the NVIDIA grpahics driver now using another
thread.
