Michael Feldman over at HPCwire has dug up an article at Heise Online that claims that IBM’s PowerXCell processor is at the end of the road
According to Heise, IBM VP of Deep Computing David Turek confirmed that there will be no successor to the PowerXCell 8i, the high performance Cell variant IBM developed for the Roadrunner supercomputer and its QS22 blades.
…Turek implied that parts of the Cell technology will live on in future heterogeneous processors, or perhaps future stand-alone accelerators, developed by IBM. That, of course, leads one to wonder if he’s talking about variants of the Power CPU line, an upcoming Blue Gene architecture, or something entirely new. For the time being, Cell users can employ IBM’s OpenCL SDK to bridge their development to future systems.
