Hi,

Thanks for the suggestions, but unfortunately I haven't gotten to the point of 
running on nodes yet. Everything runs on the head node, which uses custom mesa 
and OSMesa RPMs built from the 7.6.1 Mesa source code installed to /usr.

Are you using the stock 7.5.1 source code of Mesa? I have only tried 6.5.1 
(CentOS 5.4 flavor) and 7.6.1 so far. Could you also post the compiler flags and 
configure options you use for mesa? Maybe if I mirror your settings, it will 
work here as well.

Cheers,
