Pinned topic IBM QS22 BladeCenter 0793-40U Dual PowerXCell 8i blades used in production

‏2012-10-22T00:42:06Z |
Are IBM QS22 BladeCenter 0793-40U Dual PowerXCell 8i blades used in production environments besides the Dept of Energy *IBM Roadrunner*?
If so, what is their advantage over other types (JS, HS or LS)?

    At their introduction, the QS22 blades offered superior power efficency and density for some single-precision floating point operations heavily used in oil exploration, and a good number were deployed for this commercially. Since then advances in processor technology have negated this advantage and those machines have been retired.
