I've spent most of my OpenGL development on Linux using NVidia drivers.
In the past I've opened multiple windows each with their own thread
and GL context, and I've been able to successfully render into each
context in parallel.
The other day I tried doing so with an ATI card using both the open and
closed source drivers (ati and flxgl), but OpenGL reports that it isn't
multithreaded.
Stack trace (goes down to up):
/lib/tls/i686/cmov/libc.so.6(abort+0xe9) [0xb1af12e9]
/lib/tls/i686/cmov/libc.so.6(__assert_fail+0x101) [0xb1ae8f71]
/usr/lib/libGL.so.1(_glapi_check_multithread+0) [0xb209e090]
/usr/lib/libGL.so.1(_glapi_check_multithread+0x67) [0xb209e0f7]
/usr/lib/libGL.so.1(glXMakeCurrentReadSGI+0x13c) [0xb20b5ee5]
/usr/lib/libGL.so.1(glXMakeCurrent+0x23) [0xb20b62aa]
I want my code to run on other architectures, so I'm wondering if anyone
has had experience trying to render into multiple contexts in parallel
on other systems like Windows or Mac OSX.
Note that I'm not trying to use more than a single thread for each
context. I know OpenGL isn't that parallel. ;)
Thanks,
James
