The long wait for volume shipments of Intel’s “Knights Landing” parallel X86 processors is over, and at the International Supercomputing Conference in Frankfurt, Germany is unveiling the official lineup of the Xeon Phi chips that are aimed at high performance computing and machine learning workloads alike.
The lineup is uncharacteristically simple for a Xeon product line, which tends to have a lot of different options turned on and off to meet the myriad requirements of features and price points that a diverse customer base usually compels Intel to support. Over time, the Xeon Phi lineup will become more complex, with …

For the first time since the Top 500 rankings of the most powerful supercomputers in the world was started 23 years ago, the United States is not home to the largest number of machines on the list – and China, after decades of intense investment and engineering, is.
Supercomputing is not just an academic or government endeavor, but it is an intensely nationalistic one given the enormous sums that are required to create the components of these massive machines, write software for them, and keep them running until some new approach comes along. And given that the machines support the …
China Topples United States As Top Supercomputer User was written by Timothy Prickett Morgan at The Next Platform.
Much to the surprise of the supercomputing community, which is gathered in Germany for the International Supercomputing Conference this morning, news arrived that a new system has dramatically topped the Top 500 list of the world’s fastest and largest machines. And like the last one that took this group by surprise a few years ago, the new system is also in China.
Recall that the reigning supercomputer in China, the Tianhe-2 machine, has stood firmly at the top of that list for three years, outpacing the U.S. “Titan” system at Oak Ridge National Laboratory. We have a more detailed analysis …

Nvidia wants for its latest “Pascal” GP100 generation of GPUs to be broadly adopted in the market, not just used in capability-class supercomputers that push the limits of performance for traditional HPC workloads as well as for emerging machine learning systems. And to accomplish this, Nvidia needs to put Pascal GPUs into a number of distinct devices that fit into different system form factors and offer various capabilities at multiple price points.
At the International Supercomputing Conference in Frankfurt, Germany, Nvidia is therefore taking the wraps off two new Tesla accelerators based on the Pascal GPUs that plug into systems …

This week at the International Supercomputing Conference (ISC ’16) we are expecting a wave of vendors and high performance computing pros to blur the borders between traditional supercomputing and what is around the corner on the application front—artificial intelligence and machine learning.
For some, merging those two areas is a stretch, but for others, particularly GPU maker, Nvidia, which just extended its supercomputing/deep learning roadmap this morning, the story is far more direct since much of the recent deep learning work has hinged on GPUs for training of neural networks and machine learning algorithms.
We have written extensively over …

Might doesn’t make right, but it sure does help. One of the recurring bothers about any technology upstart is that they are smaller Davids usually up against vastly larger Goliaths, usually with a broader and deeper set of technologies covering multiple markets. The best way to get traction in one market, then, seems to be to have significant footing in several markets.
This is the strategy that ARM server chip and switch ASIC maker Cavium is taking as it shells out approximately $1.36 billion to acquire network and storage switch chip maker QLogic. The combination of the two companies will …

There are two endpoints in any network connection, and you have to focus on both the server adapter and the switch to get the best and most balanced performance out of the network and the proper return on what amounts to be a substantial investment in a cluster.
With the upcoming ConnectX-5 server adapters, Mellanox Technologies is continuing in its drive to have more and more of the network processing in a server node offloaded to its adapter cards. And it is also rolling out significant new functionality such as background checkpointing and switchless networking, and of course there is …

Open source software has done a lot to transform the IT industry, but perhaps more than anything else it has reminded those who architect complex systems that all elements of a datacenter have to be equally open and programmable for them to make the customizations that are necessary to run specific workloads efficiently and therefore cost effectively.
Servers have been smashed wide open in large enterprises, HPC centers, hyperscalers, and cloud builders (excepting Microsoft Azure, of course) by the double whammy of the ubiquity of the X86 server and the open source Linux operating system, and storage has followed suit …

Building high performance systems at the bleeding edge hardware-wise without considering the way data actually moves through such a system is too common—and woefully so, given the fact that understanding and articulating an application’s requirements can lead to dramatic I/O improvements.
A range of “Frequently Unanswered Questions” are at the root of inefficient storage design due to a lack of specified workflows, and this problem is widespread, especially in verticals where data isn’t the sole business driver.
One could make the argument that data is at the heart of any large-scale computing endeavor, but as workflows change, the habit of …

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.
To try to figure out what is going on out there with memory on systems in the real world and how future technologies might affect …

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.

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.
