AMD gets a lot of credit for creating Accelerated Processing Units that merge CPUs and GPUs on a single package or on a single die, but Intel also has a line of chips Core and Xeon processors that do the same thing for workstation and server workloads. The “Skylake-H” Xeon E3-1500 v5 chips that Intel recently announced with its new Iris Pro Graphics P580 GPUs pack quite a wallop. Enough in fact that for certain kinds of floating point math on hybrid workloads that system architects should probably give them consideration as they are building out clusters to do various …

The powerful Cori supercomputer, now being readied for deployment at NERSC (The National Energy Research Scientific Computing Center), has been named in honor of Gerty Cori. Cori was a Czech-American biochemist (August 15, 1896 – October 26, 1957) who became the first American woman to be awarded the Nobel Prize.
Cori (a.k.a. NERSC-8) is the Center’s newest supercomputer. Phase 1 of the system is currently installed with Phase 2 slated to be up and running this year. Phase 1 is a Cray XC40 supercomputer based on the Intel Haswell multi-core processor with a theoretical peak performance of 1.92 petaflops/sec. It …

With the International Supercomputing 2016 conference fast approaching, the HPC community is champing at the bit to share insights on the latest technologies and techniques to make simulation and modeling applications scale further and run faster.
The hot topic of conversation is often hardware at such conferences, but hardware is easy. Software is the hard part, and techniques for exploiting the compute throughput of an increasingly diverse collection of engines – from multicore CPUs to GPUs to DSPs and to FPGAs – evolve more slowly than hardware. And they do so by necessity.

Compute is by far still the largest part of the hardware budget at most IT organizations, and even with the advance of technology, which allows more compute, memory, storage, and I/O to be crammed into a server node, we still seem to always want more. But with a tighter coupling of flash in systems and new memories coming to market like 3D XPoint, the server is set to become a more complex bit of machinery.

There are two competing trends in platform designs that architects always have to contend with. They can build a platform that performs a specific function and does it well, or create a more generic platform that sacrifices some efficiency but does a lot of jobs well. Sometimes you try to shoot the gap between these two poles.
That is precisely what Arista Networks, the networking upstart that has serial entrepreneur Andy Bechtolsheim as its chief development officer, is doing with a new line of what it is calling “universal leaf” switches. The leaf switches (does one say “leafs” or “leaves” …

When considering system and software needs at massive scale, one application area that tends to shed light on what lies ahead is weather prediction and modeling.
Over the last year, we have had a number of pieces about what centers that deliver forecasts (and carry out research to improve those predictions) need to do to stay ahead, and while conversations about hardware and software are important, what is emerging is that weather, like many other areas of computing at scale, actually needs a platform versus innovation at one or two levels of the stack.
With that idea of a platform …

One of the things that high-end network adapter and switch maker Mellanox Technologies got through its $811 million acquisition of network processing chip maker EZchip last September was a team that was well versed in massively parallel processor chip design, and one that could make Mellanox a potential player in the server chip space.
But not necessarily in the way you might be thinking about it.
The reason this is the case is that in July 2014, EZchip, wanting to expand out beyond its networking chip business as Applied Micro, Cavium, and Broadcom have all done with ARM-based server chips, …

There are plenty of people in industry, academia, and government that believe there is a direct correlation between the investment in supercomputing technologies and the healthy and vibrancy of the regional or national economy. So getting a big bump up in performance, as South Africa’s Center for High Performance Computing has just done this week, is a big deal.
Up until now, CHPC has had fairly modest sized systems, but thanks to Moore’s Law advancements that have radically brought down the cost of compute and a more aggressive plan to invest in HPC within South Africa, CHPC is breaking into …

The datacenter is going through tremendous change, and many long-held assumptions are now being called into question. Even the basic process of separating data onto a separate storage area network, growing it, and pulling it across the network and processing it, is no longer necessarily the best way to handle data. The separation between production and analytics, which has evolved into an art form, is also breaking down because it takes a day or longer to get operational data into analytic systems.
As a backdrop to all of these technology changes, organizations say they need more agility. The ability to …

Chip startups come and go. Generally, we cover them because of novel architectures or potential for specific applications. But in some cases, like today, it is for those reasons and because of the people behind an effort to bring a new architecture into a crowded, and ultimately limited, landscape.
With $100 million in “patience money” from a few individual investors who believe in the future of sparse matrix-based computing on low-power and reprogrammable devices, Austin-based Knupath, has spent a decade in stealth mode designing and fabricating a custom digital signal processor (DSP) chip to target deep learning training, machine …

The server cycle has some long waves that are not always in phase with each other, and that is generally a good thing. But every now and then, the waves synchronize, and it is either really exciting as the market rises or something of a bummer as it falls. In the first quarter of this year, there was a bit of a dip but still an order of magnitude less dramatic than the collapse in shipments and sales during the Great Recession.
It is important to keep perspective, and it is actually quite remarkable that the server market is as …

Intel is coming to the finish line with its 14 nanometer chip making process with the launch of the “Broadwell” generation of Xeon E7 server processors in China today.
Why China? Because for reasons that are not immediately obvious but are completely beneficial to Intel, the Chinese market has for the past several years been adopting four-socket servers in large scale datacenters at a rate that is considerably higher than their peers in the rest of the world. These new Xeon E7 v4 processors will be a big hit for big iron there and anywhere else where having a big …

Networking chip maker Cavium is one of the ARM server chip upstarts that is taking on Intel’s hegemony in the datacenter, and is probably getting the most traction among its ARM peers in the past year with its ThunderX multicore processors.
The first-generation ThunderX chips are seeing the most interest from hyperscalers and HPC centers, plus a few cloud builders, telcos, and large enterprises, that want to explore the possibilities of a different server architecture, and they will be even more intrigued by the second-generation ThunderX2 processors, which Cavium unveiled earlier this week at the Computex trade show in Taipei, …

During a trip to Dell in Austin, Texas this week, little did The Next Platform know that the hardware giant and nearby Texas Advanced Computing Center (TACC) had major news to share on the supercomputing front.
It appears the top ten-ranked Stampede supercomputer is set for an extensive, rolling upgrade—one that will keep TACC’s spot in the top tier of supercomputing sites and which will feature the latest Knights Landing processors and over time, a homogeneous Omni-Path fabric. The net effect of the upgrade will be a whopping 18 petaflops of peak performance by 2018.

Back in 2009, when yours truly was assigned the primary beat of covering supercomputing on remote hardware (then dubbed the mysterious “cloud”), the possibility that cloud-based high performance computing was little more than a pipe dream.
At that time, most scientific and technical computing communities had already developed extensive grids to extend their research beyond physical borders, and the idea of introducing new levels of latency, software, and management interfaces did not appear to be anything most HPC centers were looking forward to—even with the promise of cost-savings (as easy “bursting” was still some time off).

Computing for neuroscience, which has aided in our understanding of the structure and function of the brain, has been around for decades already. More recently, however, there has been neuroscience for computing, or the use of computational principles of the brain for generic data processing. For each of these neuroscience-driven areas there is a key limitation—scalability.
This is not just scalability in terms of software or hardware systems, but on the application side, limits in terms of efficiently deploying computational tools at sufficient size and time scales to yield far greater insight. While adding more compute to the problem …

The datacenter is a battleground with many fronts these days, with intense competition between compute, memory, storage, and networking components. In terms of revenues, profits, and prestige, the compute territory is the most valuable that chip makers and their system partners are fighting for, and the ARM and OpenPower collectives are doing their best to take some ground from a very powerful Intel.
As such, chip makers end up comparing themselves to Intel Xeon or Atom processors, and Intel sometimes makes comparisons back. At the high end, Intel is battling the Power8 processor championed by IBM and to a lesser …

Having made the improbable jump from the game console to the supercomputer, GPUs are now invading the datacenter. This movement is led by Google, Facebook, Amazon, Microsoft, Tesla, Baidu and others who have quietly but rapidly shifted their hardware philosophy over the past twelve months. Each of these companies have significantly upgraded their investment in GPU hardware and in doing so have put legacy CPU infrastructure on notice.
The driver of this change has been deep learning and machine intelligence, but the movement continues to downstream into more and more enterprise-grade applications – led in part by the explosion …
