Intel Gives Exascale A Boost
Intel’s exascale computing efforts have received a boost with the extension of the company’s research collaboration with the Barcelona Supercomputing Center.
Begun in 2011 and now extended to September 2017, the Intel-BSC work is currently looking at scalability issues with parallel applications.
Karl Solchenbach, Intel’s director, Innovation Pathfinding Architecture Group in Europe said it was important to improve scalability of threaded applications on many core nodes through the OmpSs programming model.
The collaboration has developed a methodology to measure these effects separately. “An automatic tool not only provides a detailed analysis of performance inhibitors, but also it allows a projection to a higher number of nodes,” says Solchenbach.
BSC has been making HPC tools and given Intel an instrumentation package (Extrae), a performance data browser (Paraver), and a simulator (Dimemas) to play with.
Charlie Wuischpard, VP & GM High Performance Computing at Intel said that the Barcelona work is pretty big scale for Chipzilla.
“A major part of what we’re proposing going forward is work on many core architecture. Our roadmap is to continue to add more and more cores all the time.”
“Our Knights Landing product that is coming out will have 60 or more cores running at a slightly slower clock speed but give you vastly better performance,” he said.
Intel Releases 16GB Xeon Phi
Intel has announced five Xeon Phi accelerators including a high density add-in card while upping memory capacity to 16GB.
Intel has managed to get its Xeon Phi accelerator cards to power the Tianhe-2 cluster to the summit of the Top 500 list, however the firm isn’t waiting around to bring out new products. At the International Supercomputing show, Intel extended its Xeon Phi range with five new products, all of which have more than one TFLOPS double precision floating point performance, and the Xeon Phi 7120P and 7120X cards, which have 16GB of GDDR5 memory.
Intel’s Xeon Phi 7120P and 7120X cards have peak double precision floating point performance of over 1.2 TFLOPS, with 352GB/s bandwidth to the 16GB of GDDR5 memory. The firm also updated its more modest Xeon Phi 3100 series with the 3120P and 3120A cards, both with more than one TFLOPS of double precision floating point performance and 6GB of GDDR5 memory with bandwidth of 240GB/s.
Intel has also brought out the Xeon Phi 5120D, a high density card that uses mini PCI-Express slots. The firm said that the Xeon Phi 5120D card offers double precision floating point performance of more than one TFLOPS and 8GB of GDDR5 memory with bandwidth greater than 300GB/s.
That Intel is concentrating on double precision floating point performance with its Xeon Phi accelerators highlights the firm’s focus on research rather than graphics rendering or workstation tasks. However the firm’s ability to pack 16GB into its Xeon Phi 7100 series cards is arguably the most important development, as larger locally addressable memory means higher resolution simulations.
Intel clearly seems to believe that there is significant money to be made in the high performance PC market, and despite early reservations from industry observers the firm seems to be ramping up its Xeon Phi range at a rate that will start to give rival GPGPU accelerator designer Nvidia cause for concern.
Intel Goes Wireless
Maho Bay is a desktop platform wrapped around the recently launched Ivy Bridge desktop processor and Intel plans to enrich this platform with a Wireless mini card offer of its own.
The plan is to make new SKUs based on half Minicard (mPCIe) standard and offer it with its boards that have support for PCIe 1X or faster. Maho Bay also allows some combinations with Sandy Bridge processors and will allow the use of these mini Wireless cards on older processors with new boards. It looks like the Panther Point chipset is necessary even for older Sandy Bridge processors on Maho Bay platform.
The top range card with premium performance is Intel Centrino Ultimate N 6300, and the card has virtually the same specification like its mobile brother. It supports Intel Wireless Display as well as Intel My Wifi technology and quick driver connect.
Since it is using 3×3 antennas and MIMO standard it us capable of achieving speeds of 450Mbits per second and it does support multiple streams. It supports dual band 2.4 + 5 GHz and Intel Vpro. This is still a 802.11n based product as Intel hasn’t really jumped the gun to support 802.11ac in 2012.
It looks like it is too early for Intel to embrace this new standard due to its very limited market penetration.
Is Ivy Bridge Better Than Llano?
Ivy Bridge notebook and desktop chips will start to surface in late April. It all starts with quad cores on April 29th and in late May early June it expands to dual cores.
Since Anand already benchmarked Ivy Bridge desktop 3770K, we got quite a nice glimpse of what to expect from Ivy Bridge graphics. Still, our sources are telling us that the final graphics scores will end up significantly faster, once the new launch driver gets ready.
You should expect Llano-class performance from Ivy Bridge we were told. Llano scales from HD 6370 integrated graphics all the way to the HD 6550 DirectX 11 core, and Ivy Bridge scores should come very close to this.

We still don’t know the official branding of Ivy Bridge Pentium chips, but we are aware of plans for at least one SKU.
Intel plans to launch a Pentium branded Ivy Bridge and replace the G860 Pentium that currently holds the key position in L3 Legacy market. This 3.0GHz 32nm Sandy Bridge dual-core with two treads is currently available and sells for $86. Let’s not forget the 3MB cache size.
In Q2 2012 the Pentium family gets a new member, the 3.1GHz clocked G870, and both G870 and G860 get replaced in L3 market segment by an unnamed Ivy Bridge Pentium. We know that it should start selling for $86 and that this will be the cheapest of 22nm based desktop Ivy Bridge.
Ivy Bridge Specs Leaked
Intel has inadvertently leaked details of its upcoming Ivy Bridge processors in a sales flipbook uploaded to its website.
Intel’s much delayed Ivy Bridge processors are expected to tip up in the second quarter sporting the firm’s tri-gate transistor technology. Details of the chips had been relatively scant, until that is the firm decided to upload a sales flipbook, which details what appear to be most of its third generation Core i5 processors.
According to Intel’s slides there are only modest frequency bumps, with the quad-core Core i5-2570 and Core i5-2570K topping the range with speeds of 3.4GHz and 3.8GHz in Turbo mode. The addition of the ‘K’ suffix signifies Intel HD 4000 graphics, while the Core i5-3570 plods along with Intel HD 2500 graphics.
Like Chipzilla’s Sandy Bridge Core i5 chips, the Ivy Bridge Core i5 range will be all quad-core chips with 6MB of cache that lack Hyperthreading, with one exception, the Core i5-3470T, which is a dual-core Hyperthreaded processor with 3MB of cache. Previously the ‘T’ suffix was added to signify a 35W TDP chip, though this was not confirmed on the leaked slide.
