No one got fired for using Intel?

The recently fired CEO must be the third one who stayed loyal to the Intel vision for far too long. You do realize that Opterons cannot address enough physical memory for most of SGI's applications, right? 1TB limit currently. SGI systems go upto 10TB+...I think the largest I read about was a 14TB system in japan, but I'm not 100% sure. Now that could change, we'll have to wait and see what's up with the F-stepping I guess. DK |

So if you have 256 Opterons, each with 1TB of memory attached to them, then you'll have reached your limit. But I don't think even SGI's have 1TB of RAM per processor yet. Yousuf Khan |

SGI systems go upto 10TB+...I think the largest I read about was a 14TB system in japan, but I'm not 100% sure. So I did a little reading at www.cray.com and www.sgi.com ... SGI Altix clusters can theoretically go up to 128 TB. Cray XT3 (Opteron) clusters can theoretically go up to 240 TB. 1TB can be installed per processor (40-bit), but 256TB overall (48-bit) is addressable virtually. So if you have 256 Opterons, each with 1TB of memory attached to them, then you'll have reached your limit. But I don't think even SGI's have 1TB of RAM per processor yet. SGI's max RAM solution is by clustering Altix 4700's. One or two CPUs and up to 48 GB of DDR-2 per blade. Cray's XT3, IIRC, has single-CPU blades with up to 8 GB/CPU. HP sells 4P Opty blades with up to 64 GB/blade but I haven't read anything about them being used in any super-sized clusters. |
