Cray swings profit on Q4 revenue dive

Dell 'wildcard'

Ungaro said that Cray has inked deals with 40 reseller partners, including server and PC maker Dell, which has its very own Windows 7-based baby cluster, called the Cray CX1-iWS. Ungaro did not provide any kinds of shipment or revenue figures for the CX1s, but said merely that Cray needed to get resellers out there selling and that it was seeing a pipeline building for the Dell product.

He conceded it was a "wildcard" as to how much money the CX1 line could generate, but added this was also the case with the custom engineering business a few years back too. Cray hopes, Ungaro said in the call, that both the XT5, and soon the XT6m mini-MPP and the CX1 lines would deliver "significant results" that Cray could report on in the future.

As Cray has said in past quarters, the company is looking for its XT6 compute nodes, due early in the second quarter on the tail of the Opteron 6000 launch from AMD, and the next-generation "Baker" supers and their "Gemini" interconnect. Gemini is the kicker to the SeaStar2+ interconnect in the XT5 supers, which implements a 3D torus interconnect between Opteron server nodes.

Ungaro said that the Baker systems, which will pair the XT6 blades with the Gemini interconnect as well as making unspecified improvements in the system software stack on the machines to boost scalability and performance, are on track for initial development and test systems to be delivered to customers in the third quarter.

An early version of the Gemini interconnect is being tested now, and what Cray hopes to be the final version of the chip (which has been tweaked as chips always are as they are stepped through the development and manufacturing process) is out being manufactured now. "Thinks are going well, and I am knocking on wood," Ungaro said and you could hear him knock three times on his desk.

Because of the improvements in scalability and performance in the Baker systems, Cray is warning investors that "a significant majority" of revenues in 2010 will be booked in the fourth quarter. That is the inverse of 2009, which will mean that the compares for Q4 2010 will be sweet and that investors should, as Ungaro said in the call, always look at Cray on an annual basis, not quarterly.

Assuming that that the Baker machines come off without a hitch in Q3, then Cray is anticipating overall revenues of between $305m and $325m for 2010, with about $110m of that coming from services. The company exited 2009 with $113.2m in cash and short-term investments (more than double the levels as 2008 ended) and will have to burn cash to build up inventories of parts and to pay for development of the Baker machines between now and the third quarter when they start shipping.

To help push more products before the end of 2010, Ungaro hinted that Cray would be introducing a new class of super that sits between the CX1 personal supercomputer and the XT6m mini-MPP boxes. He did not elaborate on what it might be.

But if you cut a base XT6m in pieces and choose one piece, you will probably get close to what Cray has in mind rather than building up from a CX1.

The XT5 and XT6 machines implement the SeaStar2+ interconnect in a 3D torus (with six ports on each SeaStar2+ chip), while the XT5m and XT6m minis implement it in a much shallower and less scalable 2D torus that has four ports on each SeaStar2+ chip activated. One can envision a SeaStar2+ chip with maybe two or three ports active being connected in a flatter architecture but still being a cluster running the same Linux stack as the other XT machines from Cray.

There are a number of possible tree, ring, or star topologies that could be used in such a baby super. If you wanted to, with three SeaStar2+ ports turned in each node, on you could link any of number of XT6m nodes into a ring (using two ports on each chip) and use the third link to lash multiple rings together. (This would be weird, obviously).

You could also lash together four two-socket XT6 blades into something that smelled like a NUMA cluster with only two ports per SeaStar2+ chip turned on. Why this would be better than an eight-socket Opteron 6000 box is immediately obvious. AMD is not making an eight-socket Opteron 6000 box. Its SR56X0/SP5100 chipsets will top out at four sockets. Intel's Xeon 5500 and future Westmere-EP chips are only good for two-socket configurations.

If you want NUMA-oid clustering and don't want tree clustering using InfiniBand or 10 Gigabit Ethernet, Xeons don't really provide options. Unless Cray builds its first Intel-based super on the upcoming eight-core Nehalem-EX machine, which can scale well beyond two sockets, perhaps as high as 16, 32, or 64 sockets using SeaStar2+ chips as glue. This is all idle speculation, of course, for the sake of amusement. ®
