A Co-processor No More, Intel's Xeon Phi Will Be Its Own CPU As Well 53
An anonymous reader writes "The Xeon Phi co-processor requires a Xeon CPU to operate... for now. The next generation of Xeon Phi, codenamed Knights Landing and due in 2015, will be its own CPU and accelerator. This will free up a lot of space in the server but more important, it eliminates the buses between CPU memory and co-processor memory, which will translate to much faster performance even before we get to chip improvements. ITworld has a look."

- very hot card, no fans
- depends on software to down throttle the cards (mine have hit 104C)
- stripped down OS running on the cards, poor user facing directions for the usage
Anyway, enough from me.

I won't disagree about the awkwardness of MPSS, but the 'very hot card, no fans' is because it's meant only to be installed into systems that cooperate with them and have cooling designs where the hosting system takes care of it. For a lot of systems that Phi go into, a fan is actually a liability because those systems already have cooling solutions and a fan actually fights with the designed airflow.
Of course, that's why nVidia offers up two Tesla variants of every model, one with and one without fan, to cater to both worlds.

A) Stop being a pedantic dick.
B) Correct. The original 1965 paper observed that transistor counts were tending to double every year (12 months), which he later revised to every 2 years (24 months) in 1975.
What people are misquoting is the House corollary. That PERFORMANCE of microprocessors, due to increased transistor counts, and faster speeds, seems to double roughly every 18 months.
