> first of all, is 5.1 production ready? or is 4.4 still the way to go in a production environment? this would be the only install available for users so it's important that it function reliably/correctly.

> re: 5.1, I'm wondering what the recommended mesa config for use with pv 5.1 on cray is?  Which version of mesa have been tested/recommended? is open swr an option yet? or is llvmpipe still a better bet?

11.2.* is recommended. OpenSWR is not yet in official release of
Mesa3D (it's still in the RC stage), llvmpipe would still be the best
bet.
