SeaMicro adds Xeons to Atom smasher microservers • The Register

Theres some interesting future possibilities for the SeaMicro machines. First, SeaMicro could extend that torus interconnect to span multiple chassis. Second, it could put a “Patsburg” C600 chipset on an auxiliary card and actually make fatter SMP nodes out of single processor cards and then link them into the torus interconnect. Finally, it could of course add other processors to the boards, such as Tileras 64-bit Tile Gx3000s or 64-bit ARM processors when they become available.

Timothy Prickett Morgan writing for The Register, has a great article on SeaMicro’s recent announcement of a Xeon-based 10U server chassis. Seemingly going against it’s first two generations of low power massively parallel server boxes, this one uses a brawny Intel Xeon server chip (albeit one that is fairly low power and low Thermal Design Point).

Sad as it may seem to me, the popularity of the low power, massively parallel cpu box must not be very lucrative. But a true testament to the flexibility of their original 10U server rack design is the ability to do a ‘swap’ of the higher power Intel Xeon cpus. I doubt there’s too many competitors in this section of the market that could ‘turn on a dime’ the way SeaMicro has appeared to do with this Xeon based server. Most often designs will be so heavily optimized for a particular cpu, power supply and form factor layout that changing one component might force a bigger change order in the design department. And the product would take longer to develop and ship as a result.

So even though I hope the 64bit Intel Atom will still be SeaMicro’s flagship product, I’m also glad they can stay in the fight longer selling into the ‘established’ older data center accounts worldwide. Adapt or die is the cliche adage of some technology writers and I would mark this with a plus (+) in the adapt column.

AnandTech – Applied Micros X-Gene: The First ARMv8 SoC

APM expects that even with a late 2012 launch it will have a 1 – 2 year lead on the competition. If it can get the X-Gene out on time, hitting power and clock targets both very difficult goals, the headstart will be tangible. Note that by the end of 2012 well only just begin to see the first Cortex A15 implementations. ARMv8 based competitors will likey be a full year out, at least.

Chip Diagram for the ARM version 8 as implemented by APM

It’s nice to get a confirmation of the production time lines for the Cortex A15 and the next generation ARM version 8 architecture. So don’t expect to see shipping chips, much less finished product using those chips well into 2013 or even later. As for the 4 core ARM A15, finished product will not appear until well into 2012. This means if Intel is able to scramble, they have time to further refine their Atom chips to reach the power level and Thermal Design Point (TDP) for the competing ARM version 8 architecture. What seems to be the goal is to jam in more cores per CPU socket than is currently done on the Intel architecture (up to almost 32 in on of the graphics presented with the article).

The target we are talking about is 2W per core @ 3Ghz, and it is going to be a hard, hard target to hit for any chip designer or manufacturer. One can only hope that TMSC can help APM get a finished chip out the door on it’s finest ruling chip production lines (although an update to the article indicates it will ship on 40nm to get it out the door quicker). The finer the ruling of signal lines on the chip the lower the TDP, and the higher they can run the clock rate. If ARM version 8 can accomplish their goal of 2W per cpu core @ 3 Gigahertz, I think everyone will be astounded. And if this same chip can be sampled at the earliest prototypes stages by a current ARM Server manufacturer say, like Calxeda or even SeaMicro then hopefully we can get benchmarks to show what kind of performance can be expected from the ARM v.8  architecture and instruction set. These will be interesting times.

SeaMicro pushes Atom smasher to 768 cores in 10U box • The Register

An original SM10000 server with 512 cores and 1TB of main memory cost $139,000. The bump up to the 64-bit Atom N570 for 512 cores and the same 1TB of memory boosted the price to $165,000. A 768-core, 1.5TB machine using the new 64HD cards will run you $237,000. Thats 50 per cent more oomph and memory for 43.6 per cent more money. ®

via SeaMicro pushes Atom smasher to 768 cores in 10U box • The Register.

SeaMicro continues to pump out the jams releasing another updated chassis in less than a year. There is now a grand total of 768 processor cores jammed in that 10U high box. Which leads me to believe they have just eclipsed the compute per rack unit of the Tilera and Calxeda massively parallel cloud servers in a box. But that would wrong because Calxeda is making a 2U server rack unit hold 120-4 core ARM cpus. So that gives you a grand total of 480 in just 2 rack units alone. Multiply that by 5 and you get 2400 cores in a 10U rack serving. So advantage Calxeda in total core count, however lets also consider software too. Atom being the cpu that Seamicro has chosen all along is an intel architecture chip and an x64 architecture at that. It is the best of both worlds for anyone who already had a big investment in Intel binary compatible OSes and applications. It is most often the software and it’s legacy pieces that drive the choice of which processor goes into your data cloud.

Anyone who had clean slate to start from might be able to choose between Calxeda versus Seamicro for their applications and infrastructure. And if density/thermal design point per rack unit is very important Calxeda too will suit your needs I would think. But who knows? Maybe your workflow isn’t as massively parallel as a Calxeda server and you might have a much lower implementation threshold getting started on an Intel system, so again advantage Seamicro. A real industry analyst would look at these two competing companies as complimentary, different architectures for different workflows.

Atom smasher claims Hadoop cloud migration victory • The Register

SeaMicro has been peddling its SM10000-64 micro server, based on Intels dual-core, 64-bit Atom N570 processor and cramming 256 of these chips into a 10U chassis. . .

. . . The SM10000-64 is not so much a micro server as a complete data center in a box, designed for low power consumption and loosely coupled parallel processing, such as Hadoop or Memcached, or small monolithic workloads, like Web servers.

via Atom smasher claims Hadoop cloud migration victory • The Register.

While it is not always easy to illustrate the cost/benefit and Return on Investment on a lower power box like the Seamicro, running it head to head on a similar workload with a bunch of off the shelf Xeon boxes really shows the difference. The calculation of the benefit is critical too. What do you measure? Is it speed? Is it speed per transaction? Is it total volume allowed through? Or is it cost per unit transaction within a set amount of transactions? You’re getting closer with that last one. The test setup used a set number of transaction needing to be done in a set period of time. The benchmark then measure total power dissipation to accomplish that number of transactions in the set amount of time. SeaMicro came away the winner in unit cost per transaction in power terms. While the Xeon based servers had huge excess speed and capacity the power dissipation put it pretty far into the higher cost per transaction category.

However it is very difficult to communicate this advantage that SeaMicro has over Intel. Future tests/benchmarks need to be constructed with clearly stated goals and criteria. Specifically if it can be communicated as a Case History of a particular problem that could be solved by either a SeaMicro server or a bunch of Intel boxes running Xeon cpus with big caches. Once that Case History is well described, then the two architectures are then put to work showing what the end goal is in clear terms (cost per transaction). Then and only then will SeaMicro communicate effectively how it does things different and how that can save money. Otherwise it’s too different to measure effectively versus a Intel Xeon based rack of servers.

“Pine Trail”-Intel’s next Atom CPU revision

In the netbook manufacturing and product development industry, the next big thing is always Intel’s rev of the CPU and chipset. Cue the entry of the Pine Trail CPU and it’s partner I/O Hub chip. Only just this year has Intel shown a willingness to combine functions onto the same processor die. I am very interested to see that the CPU is combining not just the Memory Controller as is the case the top of the line i7 CPU family. Talk about a weight reduction right? The original chipset consisted of no less than 3 processors a North Bridge and South Bridge along with the CPU. Now with the coming of the Pine Trail, it’s a big CPU/GPU/Memory combo and a single I/O hub. I’m hoping the power consumption improves and comes much closer to the proposed specs of the Android based netbooks that will use Smartphone CPUs like Motorola’s or ARM based System-on-Chip custom CPUs. If Intel can combine functions and get battery life for a 3-cell unit to average 8+ hours under even heavy CPU loads, then they will have truly accomplished something. I’m looking forward to the first products to market using the Intel N450, but don’t expect to see them until after Christmas of this year 2009.

The Intel Atom

It should use the technology behind Pineview and would be made built on a new, 45 nanometer design that merges the memory controller and graphics directly into the processor; accompanying it would be the new-generation Tiger Point chipset, which is needed for and takes advantage of the N450 design.
