[erlang-questions] Erlang and Larrabee CPU
Sun Apr 5 00:54:02 CEST 2009
Those are good points Tim, I've also came over the following while reading
up on Larrabee:
"A different version of Larrabee might sit in motherboard CPU sockets using
but Intel has not yet announced plans for this"
The following article
also aludes to the possible future works of something like larrabee running
directly in a CPU socket. By the way, at the end the mentioned "Gesher" cpu
is currently known as "Sandy Bridges" (6-8 core, should be released this or
In any case, I just think that Erlang has a lot of potential for some
hardcore computing (I primarily use it for computationally intensive
projects on quad cores, and it's been working very well), and that we have
not yet utilized Tesla and similar potential "processing force multipliers"
is sad since Erlang can really scale on those easier than other languages.
