From the Autodesk Softimage Hardware Certification FAQ:
Q: What version of Linux does Autodesk use in the Softimage graphics certification process?
A: Autodesk Softimage 2012 graphics certification testing was performed using Fedora Core 14.
OS: Fedora 14 64bit OS
Kernel Version: 22.214.171.124-83.fc14.x86_64
Xorg Version: 1.9.4-1.fc14.x86_64
Glibc Version: 2.13-1.x86_64
The glibc version is missing from the FAQ page, but it’s a safe bet that it’s the same version used for the Maya certification.
