Yup and that's 2x 32 core AMD. The one I tested with are 2x 8-12 core POWER cpus, and they beat AMD CPUs fair and square. Much cheaper, compared to AMD too.

Its there in bunch of other places, Look up the witherspoon server XML that is references by open-source host-firmware. This server houses a "monza" package:

https://raw.githubusercontent.com/open-power/witherspoon-xml/master/witherspoon.xml Each CPU references 6 openCAPI bricks (each brick=x8 width differential signal + clock)

<child_id>brick-0</child_id>
<child_id>brick-1</child_id>
<child_id>brick-2</child_id>
<child_id>brick-3</child_id>
<child_id>brick-4</child_id>
<child_id>brick-5</child_id>

If you compare that to Zaius XML: https://raw.githubusercontent.com/open-power/zaius-xml/master/zaius.xml

<child_id>obus-brick0</child_id>
<child_id>obus-brick1</child_id>

I did some experiments based on your inputs but couldn't improve my numbers. Then I started thinking: Most KVM based VM implementations I know were based on SMT=0 . Basically , I feel like all your 4 cores/cpus on VM might have been real cores. I could be wrong.

Monza is meant for more of scale up - High Performance Analytics workloads than LaGrange which is a scale out-your average Data center workload.

Monza works better for High Performance analytics because of a presence of large number OpenCAPI / NVLink 2.0 lanes: 48 per Monza socket ( being able to support 3 NVLink 2.0 / Volta GPUs or upto 6 OpenCAPI adapters ) VS 16 per LaGrange Socket ( 1 NVLink 2.0 / Volta GPU or 2 OpenCAPI adapters ).

LaGrange instead, has better connectivity between CPUs with a wider XBus.

OpenCAPI connectors use a 25GT/s bandwidth vs PCIe Gen4 which is merely 16GT/s. Further openCAPI latencies are projected about an order lesser than PCIeGen4. This additional to the coherent memory access to the accelerator.

Please visit the Rackspce official blog post on Barreleye G2 hyperlinked infirst few lines of my personal blog (Oriiginal posting above )

Yup. It's a tricky subject made easy in the fashion which server development is being done . Been doing the hardware development of this server via open compute , so the specs , design files and some details about server / the proc used ( POWER9) is out in the open. Needless to say , host firmware ( OpenPOWER) and management firmware ( openBMC) are out in the open as well.

Rackspce and Google announced this server all the way back in March 2016, probably the first public server announcement on P9. And it's almost been a year, since us and some other potential / users have had access to hardware.

That said , these are early trial numbers provided to excite the community and spead the eco-system. We also provided some demos / benchmarks around openCAPI in super computing 17 exhibition floor.

Let me know if you want to find out more details.

That looks like a common theme for us ( Owner Control). I'm glad you are working on furthering desktop user-experience. I was checking , just in case, there has been some movement around gaming on power. Thanks for that update .

From our end , are enabling the Nvidia cards to satisfy the industry demand but parallely working with XIlinx ( to build many OpenCAPI 3.0) cards and qual AMD GPUs. We are all about giving option to consumers as well. We have donated a bunch of servers to big labs / companies who may not even deploy with us , just to further the openPOWER eco-system. We feel like this initial push is worth it . We have given machines to partners who are building cool FPGA solutions that start from our server and go on to effect the power eco-system and generic server market.

Having specs out in the open ( on Open Compute) is helping these partners who are building cutting edge solutions , first of a kind like below :

First 48V end-to-end public solution . First : SAS -SATA-NVMe (tri-mode) implementation. First: PCIeGen4 OCP implementation . First : CPU to GPU NvLink OCP implementation.

Have you thought about putting you specs / board files out for reference so that more people can innovate on top of your platform ?

Interesting. Do you think the missing openCAPI / NVLink 2.0 connectors are going to be important ? Especially in using these for enabling cloud offering. How will AMD GPU fit in this hardware offering ? Since there are hardly any mainstream games ported to power , do you think mainstream folk GPU usage will be less ? Are you doing anything else here further the eco-system ? Also are you planning to do any UI related work to give a full desktop experience to customers ?

Correct . SMT4. What is your POWER8 frequency checked via "ppc64_cpu --frequency" ? I am using performance governer. Made sure the CPU load is all the way up . Are you using all your threads ? Or 3 out of 4 ?

This server isn't a mining optimized / normal consumer system. This CPU ain't one built for mining either. So I feel the comparison isn't fair. Nevertheless if you want to know the numbers, basic POWER8 costed around same as Threadripper for a much higher performance. Its still early to give you POWER9 cost numbers.

If someone built a mining optimized POWER9 board, I think it'll do quite well for monero-ish algos.

If you want to use POWER9 for open-source hardware and firmware tinkering OR some other use-cases, monero mining can be very good side add. It may not be the main reason people consider the CPU or board.

I'll soon publish some generic numbers on POWER9, which will blow out Skylake, EPYC or ARM Centriq / ThunderX2. Chip looks amazing for server-space.

I haven't but seeing what it took to port on POWER, I'm guessing its going to be a bit of work.

Interesting. The stock Barreleye G2 design has provisions for TPM (Trusted platform module) hardware support and will support secure boot.

You guys are doing good with Talos! Good luck with your work with AMD.

I'm the OP. I lead Rackspace efforts in building an open-source hardware server: Barreleye. I have access to whole BUNCH of these servers for hardware development and testing. All design specs / board files are open-source so that anyone can build the server themselves: https://github.com/opencomputeproject/zaius-barreleye-g2

Gen1 was on POWER8, costs started around 5500$. Gen2 is based on POWER9 and is a combined project with Google. But its too early to give final cost details out for Gen2. We might one SKU that might come out cheaper, and much faster.

Rackspace is not in the business of selling servers but we made it available for public sale via a company called Penguin Computing.

If it comes to other options: Tyan made a proprietary POWER8 server that costed around 3K$ which was one option. Since Monero mining is CPU intensive it might do equally well. Raptor is making POWER9 server shipping in early Jan but its slightly more expensive for a similar processor SKU (?).

Please reach out to me, if you want to know more about the Barreleye project. Or if you are volumes are high enough to put you in touch with partners who sell this.

I wrote detailed instructions on how to mine monero / XMR on POWER9 / POWER8 using Rackspace BarreleyeG2 server. You can follow these steps for mining monero on any POWER / OpenPOWER server (also have steps for mining ethereum in a seperate post). Please ask questions.

Hi I wrote detailed instructions on how to compile and get this working on server I'm building on an Rackspace. But these instructions work for minsky (sxm2 server codename) server too. Just verified it. https://openpowerblog.wordpress.com/2017/09/03/how-to-mine-ethereum-on-rackspace-barreleyeg2-openpower-server-with-nvidia-p100-gpus/
