back to article IBM details PowerPC microserver aimed at square kilometre array

IBM has revealed more about a PowerPC microserver it says will help to crunch data gathered by the square kilometre array (SKA), the colossal radio telescope to be built across South Africa and Australia. Once operational, the SKA is expected to generate around an exabyte – a million terabytes - of data each day. Even sorting …

In the past...

I've been in the habit of using my PC hand-me-down hardware for my pet projects at home. But recently reconsidered trying out an Intel atom based SoC server board. Unfortunately as Intel seems wont to do these days they are bit miserly with PCI-e lanes. If only something like this IBM kit were available reasonably cheap. Not for a supercomputer mind you. 24 threads is totally not overkill for testing out software.

Put it in a laptop!

OK, so the water-cooling might be a problem. And 16A is a lot for a laptop power supply to put out, even if it's only at 1V. But I wouldn't mind having a scaled-down version. Hell, 4 physical cores would easily handle simultaneous building, testing, and interactive use (editing and the like).

I don't think there's been a non-Apple PPC-based laptop since the Thinkpad 860 in 1996.

' while chewing up between 15.5 and 16 amps.'

Were you trying to talk about power here? Me thinks you need to learn a bit about units....

It may draw that much current but without some idea of voltage we're kind of in the dark.

Re: ' while chewing up between 15.5 and 16 amps.'

If you watch the video it's operating a approx 1 volt. So unless my mind is truly gone tonight that would mean the same amount of watts as W = V * A. To be fair I had the same question about the article.

The screen shows and the narrator says it's 1 volt.

At least THAT one

At least THAT one should be RF-quiet enough to put amongst the radio antennas.

Re: At least THAT one

No Way is it quiet enough

It will still have to go inside a Faraday Cage, buried underground.

Re: At least THAT one

The design will be water-cooled. This is just a testing platform. For details visit www.research.ibm.com/labs/zurich/microserver/

Re: At least THAT one

That's all right, then, and thanks. I'll avoid putting one next to *my* radio antennas.

I am wise to this trick!

Pretending this is not meant to run the alien Persona/AI once download has occurred.

The Microserver will be Water-Cooled

Thanks for your comments. To be clear, this microserver will eventually be water-cooled with no fans. We will show it off at the CeBIT Fair in Hannover in March. Please stop by and take a look.

Thanks, IBM Research Team

Dear IBM research team

Damn fine work. Carry on.

It's a fine line....

...between watercooled and hosed. Mixing electrickery and water can only end badly - that's why I don't keep my data in the cloud.

So power-efficient that it needs to be water-cooled ... WTF ??

There's never an ARM server around when you need one, is there ??

(Despite 17 companies in the business)

Efficiency times Density equals Watercooling.

A human brain is super efficient but is water-cooled anyway. Generally.

Water cooling

They do intend to put 128 of the micro servers in a 2U rack unit along with 6 terabytes of DRAM. So excluding power for the DRAM that's 2KW. If they fill a rack with them that's 40KW. That enough water for 4 continuous hot showers.

12 actual and 12 virtual cores

BTW - it's not 12 actual and 24 virtual cores - it's 12 of each.

Re: 12 actual and 12 virtual cores

It is a 12 core CPU with the ability to run 2 threads at once on each core. No different than what intel does with hyperthreading on many of their CPUs.

So 12 physical cores, 24 virtual cores. Your OS would see 24 CPUs.

Last time I worked on a water-cooled IBM box we had to identify the fungus growing before we could 'debug' it.

Power(less)PC

Not sure where the power for this SKA is going to come from. Unless you're generating your own power you only have a choice between these providers:

1) Eskom

2) Eskom

3) Eskom

We experience country-wide rolling blackouts daily from 8am to 10pm because the power plants have fallen into such disrepair that they break daily and reliable power supply has become impossible (Goooogle "majuba silo collapse" as an example). The other huge problem is cable theft.

So-o-o-o..... Plenty of sunlight in the Karoo. Not sure how many solar panels / wind turbines one will need to drive thousands of these 16amp processors with cooling (you're going to need it...). Not sure how you're going to keep the locals away from your copper cable (or anything metal basically, like manhole covers, train rails, trains, fence posts, ...).
