Liquid Computing Dries Up

Search Results for: "liquid computing"

liquidThe first half of the previous decade brought about quite a series of HPC startups.  With the advent of widely accepted, commodity HPC; startups popped up across the industry with offerings in tightly coupled cluster platforms and a score of software offerings.  One such startup, Liquid Computing, latest longer than most, but will soon close its doors.

According to an article in the Ottawa Citizen, the Canadian platform vendor was recently unable to find additional funding to further development and operations.  Last week, 20 of the Ottawa-based employees were laid off.  Chief exec, hired only 14 months ago to bring the company back around, has also left.

We thought we were in position for a new round of funding but two of our three major investors were unable to contribute,” Liquid chairman Adam Chowaniec said Thursday.

We have no alternative, but to start winding down the company to preserve as much of the intellectual property as possible.”

Founded back in 2003 by former telecom engineers, Liquid raised a total of ~$50million US in order to develop their “unified computing” platform.  The platform stood as one of the first unified compute and networking platforms with an integrated software stack but failed to gain much traction in HPC.

After going through a rough spot roughly eighteen months ago, the company refocused their efforts and energy on traditional data center markets.  Unfortunately, this meant direct competition from IBM, HP, Dell and the new Cisco unified computing solution.

The company and its investors tried to find additional streams of funding, but it just didn’t work out in time.

Pat DiPietro, a Liquid director and partner with VG Partners, formerly VenGrowth, said backers “are trying to assemble a package to keep the company going but there is just no capital anywhere.”

Liquid, as with many startups, had a real issue with identifying their core markets and core competencies.  HPC, as a whole, is niche.  Generally speaking, its a tough market to break into with a very fickle set of customers.  I hope the employees of Liquid have success in finding fruitful employment soon.

Liquid Computing sheds staff

Search Results for: "liquid computing"

Timothy Prickett Morgan at The Register has a story today about Liquid Computing shedding staff as it tries to remain viable. Liquid is a company that we kept an eye on for a while, until we lost the bubble on them when they dumped their proprietary interconnect in 2008 and switched to Ethernet in a move that shifted them away from the HPC market. From coverage at the time

According to Keith Miller, vice president of product management at the company, a proprietary architecture was suitable for the high performance computing customers that Liquid Computing was targeting. But if you want to run off-the-shelf Linux distros and Windows and sell to a broader market, you have to support some other networking scheme.

Apparently that move isn’t working out for them either.

The word on the street this week is that Liquid Computing, an upstart server maker that has rejiggered its product line a number of times to try to get some traction, has laid off some workers as it tightens its belt in these harsh economic times. Liquid Computing has just confirmed those rumors.

Liquid Computing bails on its proprietary interconnect

Search Results for: "liquid computing"

Now, this is interesting. Story at The Register

Liquid Computing logoIn the IT business, volume is everything. And when people talk about standardization, this is what they really mean. Liquid Computing – a company that entered the server space with such a big splash (and a very sophisticated design) – has learned this lesson the hard way. And with its second rev of products, the company has ditched its proprietary server interconnection scheme and adopted Ethernet.

The company’s IQInterconnect plugged into the AMD’s HyperTransport to create a box that could be configured and reconfigured on the fly. But, no more…this moves the company out of the HPC space and puts it in that broader server/low end HPC market where boxes are some things to everyone and therefore not really great at anything

According to Keith Miller, vice president of product management at the company, a proprietary architecture was suitable for the high performance computing customers that Liquid Computing was targeting. But if you want to run off-the-shelf Linux distros and Windows and sell to a broader market, you have to support some other networking scheme. Ethernet is the default commercial interconnection for servers the world over, even if it does not have many of the advantages of IQInterconnect, such as being able to couple SMP nodes tightly for 16 or 32 socket images.

The performance price was stiff

The Ethernet bandwidth, at 84 Gbit/sec for module-to-module links, is a lot less than the IQInterconnect, which offered 100 GB/sec of bandwidth between modules.

Liquid Computing Board Ousts CEO

Search Results for: "liquid computing"

Apparently, the board of directors at Liquid Computing did not see eye-to-eye with co-founder and CEO Brain Hurley. They have asked him to leave in favor of appointing Greg McElheran from Axis Capital acting CEO. A Liquid spokeswoman attributed the change to the board of directors deciding to take the company in “another direction.” This is rumored to include expanding their business beyond high performance computing.

Liquid Computing logoWhile Hurley is a technologist, with a degree in electrical engineering and experience with Nortel, McElheran’s background is deal maker. Prior to joining Axis, he was a lawyer with Lucent Technologies and, according to his bio, served as the lead lawyer on “a number of multi-billion dollar transactions.”

Liquid had received a total of $41 million in two rounds of funding from an investment group made up of Axis Capital, Newbury Ventures, VenGrowth, ATA Ventures, Business Development Bank of Canada, Export Development Canada and Adam Chowaniec.

AMD Delays Barcelona Ramp-Up to Q1 2008

Search Results for: "liquid computing"

AMD has announced that it has revised its plan to ramp-up production [and subsequent availability] of the quad-core Barcelona chips from Q4 of 2007 to Q1 of 2008. In October, they stated that Barcelona silicon would be “widely available” by the end of the year.

There has been widespread speculation that the major delay in rollout is due to an erratum in the translation lookaside buffer [TLB]. The issue was made public by AMD some time ago and can be fixed with a BIOS update, but at the supposed cost of 10-20% of performance.

Barcelona silicon has been available to several HPC customers already in Q4. Appro is constructing a cluster for LLNL based on the Barcelona and Liquid Computing has announced no issues.

Liquid Computing reaches hard with HPC Challenge results

Search Results for: "liquid computing"

I’m happy to see Liquid talking publicly about performance results on the HPCC benchmarks. But their marketing seems unnecessarily aggressive and a little too enthusiastic.

The title of their press release is “Liquid Computing throws down the gauntlet with HPC Challenge results,” subtitled “LiquidIQ beats Cray XT3’s posted latency performance.” They go on to cite these results:

HPCC ping pong minimum latency of 0.46 microseconds and a maximum latency of 2.58 microseconds. Liquid’s HPCC ping pong latency is one third of the latency posted by Cray XT3 on the HPCC benchmark (Reference HPCC data: http://icl.cs.utk.edu/hpcc/hpcc_results.cgi).

HPCC Random Ring and Natural Rings latencies are measured at 3.63 and 3.00 microseconds, respectively. Liquid’s latencies are less than half of the latencies posted by Cray XT3 for the same tests.

They are clearly focused hard on “beating” Cray. This doesn’t make any sense to me. This company isn’t positioned significantly in the scientific market right now, and at any rate has technology that is way too new to claim can be successfully deployed at the scale that Cray and the other “old timers” can. In fact, their own “about” text at the foot of the press release says the following:

Liquid Computing Inc. is first to deliver a new class of computer system called LiquidIQ™ to meet the needs of scalable computing users within Enterprise High Performance Computing, xSP and Telecom markets.

While I’m sure Cray would sell to these guys, none of these markets are primary targets for Cray today and probably weren’t in the design criteria for the XT3. Now, they seem to have good technology, and may well a vendor of large-scale HPTC solutions one day. But they aren’t there yet, and so the comparison seems a little vacuous.

True, Cray is the the elder statesman of the supercomputing companies and has an incredible legacy. But we are long since past the days of Cray’s dominance of the market. Today we have a vibrant HPC market with offerings that meet a variety of needs. No one offeror is “the” choice anymore and swinging this hard at Cray smells a little desperate.

Then there’s the matter of their specific results. Yes, 3-ish microseconds is a fairly good time. But there are seven systems, including two XD1s from Cray (no longer available; fair enough), with sub 3 microsecond times, and 4, including SGI and NEC, with 3.x microsecond times. What about those? Not worth a mention?

Also, they only quoted two performance figures: what about the other seven? The whole point of the HPCC is to provide information to the community that illuminates a broader range of a machine’s performance dimensions. If random ring latency isn’t important to me, I don’t guess I care how the Liquid machine stacks up to the XT3.

Overall this looks like a rookie mistake by a new company trying to make a name and a market for itself. Rookie mistakes are easy to make, and I certainly won’t hold it against them.

But I’d suggest they take a moment, breathe deeply, focus on the technology, deploy solid systems, and let their market grow. They have a long time, and a lot to prove, before they need to start tearing into other companies to support their own growth.

Liquid Computing

Search Results for: "liquid computing"

I’m very happy to see a new crop of hardware vendors popping up that are doing new things. Companies like SiCortex and Liquid Computing. Mind you I’m not assessing the technology (yet: but I do have in depth assessments of these offerings in the works), I’m just glad that somebody out there is doing more than the regular old stuff. If there’s one thing we need in HPC these days, it’s some new thinking.

A feature that I do think is interesting about the Liquid Computing offering is the engineering they’ve invested to allow the system to be sliced up. The processors can be decoupled from memory, networking, and the I/O system.

So, for example, rather than bandwidth being given to the first packet that shows up, processes and processors can be assigned priorities that determine who gets resources and in what order.
