well, i don't think anyone guessed 'prism' was the next sgi brand ripoff rackable was going to use.

The XL thing reminds me of the Challenge XL and such, Its all CUDA and the like nowadays anyway. oh well.

It's a cool product and I like the glossy sales write up (but then I also have a thing for fancy packaging and shiny stuff etc :D ) But I don't see what is so special about it other than just a 2 socket opteron system with pci slots.

A few years ago I heard that soon x86 processors would just become glorified I/O controllers (probably an nvidia presentation) and the real processing would be done with accelerator boards. For those x86-haters out there, this can't be bad news :)

SGI Prism XL's innovative platform leverages optimized PCIe infrastructure and is uniquely designed starting with the PCI slot and then crafted with enough I/O and memory for a complete system. This sets the platform apart from other...

Not just a 2 socket opteron system with pci slots, a 2 socket opteron system with lots of pci slots.

I think that the intended spin is buy this, stick a bucket-load of CUDA cards in it and away you go. massively parallel computation power with high PCIe I/O throughput..

My previous thesis supervisor did work on computing surfaces (~16384 processing elements) before coming to Australia.. It seemed not excessively successful in it time, but anyway..

CUDA looks interesting on paper, but even with this laptop with the CUDA sticker on it, I could not be bothered.

If it keeps the bills paid that keep Supportfolio and TechPubs online and available, I have no problem chatting up the current products at work. Can it really be that much worse than when they blow stupid amounts of money on commodity-inspired hardware from IBM and HP that they never use in a productive way?

Ah, and I see they're still using the offset dual-layer gratings on the cabinets...

per the technical specification:

Processors:
    AMD Opteron™ 4100 series, two per stick

Memory, I/O and Storage:
    8 DDR3 DIMM slots per stick
    2, 4, 8, and 16 GB 1333 MHz ECC reg. DIMM
    Four 2.5 in. SATA2 drives per stick
    250GB, 500GB, 1 TB capacity
    One PCIe x 16 slot for accelerator
    One PCIe x 8 slot for Infiniband interconnect


but in the white paper: "Mojo Stick Block Diagram: Optimized for x16 PCie Double Wide GPUs Supports up to 2 Double Wide GPUs per Stick and 2 Low Profile PCIe Cards per Stick" This one makes sense for me.

Still, this is far less confusing than the pre-rackable products. Remember VUE?

I saw that there is also an Altix ICE 8400 with the 6000 series processors.

The yesterday announced SGI Jolt Technology for Altix UV looks much more interesting and SGIsh than this Prism XL. 2^18 cores and 8 PB shared memory - Oh yeah!

I was confused as well and I think that someone in marketing has mixed up "stick" and "slice".

Each SGI Prism XL stick contains two slices that are identical in configuration, mirrors of each other.


A pretty neat system I think, it would be nice to see some comparisons with other systems in terms of flops/cubic inch and power consumption. It makes me wish I was still at my previous employer, I could have convinced them to buy some serious SGI gear :)

Not much is anymore. Everything is pretty much just a repackage of the same Intel/AMD/whatever CPUs/ASICs, possibly with a slightly different form factor.

But, to paraphrase you - it might be cheap junk, but it's cheap and works OK, and that's what sells now.
Damn the torpedoes, full speed ahead!

There are those who say I'm a bit of a curmudgeon. To them I reply: "GET OFF MY LAWN!"

A workstation...
That was funny. I have not laughed like that in ages.

Also, why did they change the damn grille? The fuel cake yellow was good enough. They had to go for slime green next.
