Timothy Prickett Morgan over at the Register Has a nice article on IBM doubling up processors to fit into a single socket. In some servers this may push the limits of the number of thread Linux can handle so expect patches to push this up further in the future. The article also has lots of other juicy details on the Power 7+.

I wish they would make one that I could drop in an athlon socket. I would rewrite my BIOS in a heart beat.

Author Timothy Prickett Morgan over at the wonderful site The Register has saved us from doing a lot of work by doing some intelligence analysis of IBM’s roadmaps. Highlights include a die shrink to 32nm, 80MB shared L3 cache, cryptographic accelerator, speed bumps, POWER 8 speculation, and pretty pictures.

While all of this will allow us to run vi faster, its not all a bed of roses. The increased cache size will reduce data stalls thus reduce the effectiveness of multithreading which relies on stalls to give it time to work. You can’t have it all.
