[edit] Name

Are there any sources that confirm that the Black Widow will be officially named "X2"? Letdorf 11:26, 18 April 2007 (UTC).

[edit] X2 now just a processor blade?

It appears from recent Cray publicity that they are now using the "X2" name for a vector processor blade for the XT5h system, rather than a standalone vector supercomputer system as previously expected. Also it appears that the YARC router has been dropped in favor of the XT5h's SeaStar2+, but it's difficult to find any hard confirmation of this. I think this article needs to be updated to reflect the current reality. Letdorf (talk) 16:26, 10 March 2008 (UTC).

I've now updated the article to (I hope) more accurately reflect reality. Letdorf (talk) 17:10, 25 March 2008 (UTC).

You need to update the article again to properly reflect Cray's reality. According to the PDF for the X2 blade, BOTH interconnect technologies are included. X2 blades talk to *each other* via YARC, but talk to the Opteron/Linux/Lustre/login/etc nodes via SeaStar2+. The diagram shows what appears to be a bridge chip between the Yarc chip and the SeaStar2+ chip.

Thanks for the tip, I've revised the article to describe both interconnects now. Letdorf (talk) 09:31, 29 May 2008 (UTC).

You've almost got it right now. ;) There are 4 processors per node, and 2 nodes per blade. Thus, there are 8 processors per blade and up to 128 GB of RAM. You have stated there are only 4 processors per blade. Hardwarefreak (talk) 07:45, 4 June 2008 (UTC) Stan Hoeppner, St. Louis, MO, USA

BTW, it would be beneficial to add the X2 blade PDF to the external links section of the article. Hardwarefreak (talk) 07:49, 4 June 2008 (UTC)

Whoops, didn't spot that - edited accordingly now. Letdorf (talk) 10:39, 4 June 2008 (UTC).
