PGI to Deliver OpenACC for Intel Xeon Phi

Search Results for: OpenACC

This week the The Portland Group announced plans to extend its PGI Accelerator compiler technology with OpenACC to Intel Xeon Phi coprocessors. Using their existing code bases and with only minor modifications to their build scripts, software developers using PGI Accelerator compilers will soon be able to target Intel Xeon Phi coprocessors as well.

Until now, industry CIOs and government and university lab directors have encountered difficult decisions when evaluating accelerator technologies,” said Douglas Miles, director, The Portland Group. “Do we wait to see which technologies win out? Which programming model or models do we choose? How do we retrain developers to use these programming models? Will our applications be future-proof and portable across the different types of host CPUs and coprocessors? PGI Accelerator compilers will make Xeon Phi coprocessors programmable using standard OpenACC directives that are fully compatible with the accelerator application development efforts already under way at most significant HPC centers and sites.”

First announced in mid-2009, PGI Accelerator compilers provide a high-level coprocessor programming model intended for scientists, engineers and other domain experts who aren’t full-time programmers. PGI Accelerator Fortran 2003, C and C++ compilers enable programmers to offload compute-intensive portions of an application to a coprocessor by adding portable compiler directives, treated as comments by other compilers, to existing standard-compliant programs and recompiling with appropriate compiler options. In 2012, the PGI Accelerator compilers were enhanced to support the new de facto standard OpenACC directives.

The OpenACC standards group has posted a draft of the new OpenACC Version 2.0 specification at the SC12 Conference. With new controls over data movement including better handling of unstructured data, the new version allows for superior performance in parallelizing code and an improved developer experience.

OpenACC is an open standard designed to be easy to use, and performance portable across multiple architectures,” said Duncan Poole, President of OpenACC. “Our goal is to provide the developer ecosystem with a comprehensive and robust model for portable accelerator programming. We look forward to incorporating public feedback into this draft as well as features new to accelerators, such as dynamic parallelism, in the final version.”

As evidenced in this SC12 Show Guide, OpenACC will be all over the SC12 show floor this week. Be sure to check out the OpenACC tutorials and BoFs as well as demos from CAPSPGI, and Rogue Wave.

Hengeveld: SC12 – A Path to Discovery, Changing Course through Outer Space

Search Results for: OpenACC

In this special guest feature, Intel’s John Hengeveld looks ahead to the SC12 conference.

The HPC industry is driving fast down a familiar road. SC12 represents a sharp turn for the industry. We are going to see inflection point in Salt Lake City in a few dimensions. I am beyond excited by the dynamics of this industry today.

Let me share what I am looking for:

In the past year, Big Data has emerged as a premier investment in business and academia. The use of HPC in the analysis of Big Data and how Big Data technology is going to evolve beyond Hadoop is going to be a major topic of discussion in the sessions and in the industry. How will storage change? How will compute change? How will this increased data bandwidth requirement be reflected in emerging interconnect models? I expect to find answers to these questions at SC12.

The top 10 supercomputers will be very interesting this time around. There has been relatively little change in the past 2 lists in the top10. It will be fascinating to see if there is a lot of change. How high up will the Titan monster go? What efficiency will it achieve? What other new systems will there be in the top 10? One very well informed person said to me in Hamburg “This top500 list is the last gasp of the dying blue gene architecture…” Is he right? Will BlueGene resurge? Or will hybrid architectures begin to retake a leadership role?

In the past year, there has emerged two competing groups are developing solutions for programming highly parallel compute devices. NVidia’s OpenACC has split off an approach to address GPU Computing and is trying to establish a competing standard to OpenMP. OpenMP last week announced its draft approach for targeting directives that support CPU, GPU and highly parallel CPU’s like Intel® Xeon Phi™ coprocessors. Very serious people are supporting each approach; Intel is supporting OpenMP 4.0, of course. Some people are trying to support both. It will be interesting to see how heavily NVidia hawks their approach.

What will the industry say about Intel® Xeon Phi products? In June, Intel announced this branding for products for the now famous Intel® Many Integrated Core (MIC) architecture. Is the industry moving these products into reality? What is the time table? What are the products? How many people are taking this architecture approach seriously?

We have seen some announcements about SGI and Cray new architectures leading up to SC12. What will we hear more about them? How will the major OEMs respond? Cray just went live with their press release on Cascade (X30). Looking forward to event that announces it.. and of course the Cray Party.

What is happening in the storage world in support of HPC and Big Data? What about any new technologies to help improve IO bandwidth?
Are there any new approaches for the missing middle? – Lots of hype so far – where are the proof points and examples?

The industry is going a thousand miles an hour towards exascale and deep Petascale. But it’s a bit cloudy and just how the path will change ahead is unclear. In about a week I think we’ll know where we’re going.

Editor’s note: insideHPC would like to send out condolences to John Hengeveld and his family. His wife Jen’s brother died in a tragic car accident this week. If you see her with John at SC12 next week, he says to be sure to give her a hug.

OpenACC on a Roll with Growing Developer Tool Support

Search Results for: OpenACC

Today the OpenACC standards group announced growing support for OpenACC-supported development tools, and initial results from programmers who have been using the recently-released OpenACC compilers to accelerate research.

Using PGI’s OpenACC compiler, we ported a computational fluid dynamics (CFD) application benchmark to a general purpose GPU-based system,” reported NASA researchers in an upcoming research paper. “OpenACC is a much easier way to accelerate applications than other programming approaches, and we saw an immediate speed up of the benchmark on multiple tests, up to 10X faster compared with a single CPU core-based system.”

I met with members of the OpenACC standards group last week and it is clear to me that Directives are simply a much more efficient way to port codes to accelerators, especially on massive hybrid systems like the Titan Cray XK7.

As evidenced in this SC12 Show Guide, OpenACC will be all over the SC12 show floor next week. Be sure to check out the OpenACC tutorials and BoFs as well as demos from CAPS, PGI, and Rogue Wave. Read the Full Story.
