Mont-Blanc present at ISC2013

The 2013 International Supercomputing Conference (ISC’13) last week concluded its 28th meeting, held in the Leipzig Congress Center, drawing 2,423 attendees from 47 nations, as well as 153 leading high performance computing vendors and research organizations from around the world.

The Mont-Blanc project is investigating whether clusters based on low-power embedded components can meet the future needs of Exascale HPC. The performance of the Mont-Blanc systems will be quantified using eleven real Exascale-class scientific applications.

Mont-Blanc warms up for Exascale at SC13, Denver

For the first time at a major conference, Mont-Blanc will have dedicated space on the exhibition floor at SC13 in Denver. We will be at booth number 3741, which is shared with the other European Exascale projects, DEEP and CRESTA.

Mont-Blanc collaborates with...

CrestaCRESTA brings together four of Europe’s leading supercomputing centres, with one of the world’s major equipment vendors, two of Europe’s leading programming tools providers and six application and problem owners to explore how to meet the Exaflop challenge. CRESTA focuses on the use of six applications with Exascale potential and uses them as co-design vehicles to develop an integrated suite of technologies required to support the execution of applications at the Exascale. The applications represented in CRESTA have been chosen as a representative sample from across the supercomputing domain including biomolecular systems, fusion energy, the virtual physiological human, numerical weather prediction and engineering. Over the duration of the project, the aim is to deliver key, exploitable technologies that will allow the co-design applications to execute successfully on multi Petaflop systems, in preparation for the first Exascale systems towards the end of this decade.

Alex Ramirez: Message from the coordinatorWelcome to the third edition of the Mont-Blanc Newsletter, shortly after the International Supercomputing Conference 2013 in Leipzig.
The project is halfway through its 3-year lifetime, and the Mont-Blanc prototype is well under way. We have just received the first batch of test boards for the compute nodes, and they are already booting and running the HPC system software stack.

We have also completed deployment of the HPC software stack, including runtime and compiler support for OpenCL, in order to make full use of the Samsung Exynos 5 Dual SoC: the ARM Cortex-A15 cores and the ARM Mali-T604 GPU. We have completed a performance and energy efficiency evaluation of the Mali-T604 GPU using a number of HPC kernels, and now it's time to move on to distributed-memory parallel kernels, and full-scale applications.

The recent announcement by Samsung of the second revision of their Exynos 5 Octa SoC, with four ARM Cortex-A15 cores and an improved ARM Mali-T628 GPU, shows that there is a promising roadmap ahead for the Mont-Blanc architecture. The Exynos 5 Octa would already offer twice the CPU performance and 50% higher GPU performance, without a significant impact on the system’s power and energy efficiency, less than one year after the first Exynos 5 Dual SoC.

In parallel with the hardware development, we have added FORTRAN support for OpenCL kernels to the OmpSs (Mercurium) compiler. The compiler now supports multicore architectures, CUDA accelerators, and OpenCL accelerators, all orchestrated by the runtime software layer, and hiding the complexity of data transfers from the programmer.

We will be showcasing the first Mont-Blanc prototype hardware in the Supercomputing event in Denver, in November. The Mont-Blanc project will join forces with the other two EU Exascale research projects (DEEP and CRESTA) in a joint booth, where you will find the latest updates on the different (complementary) paths to Exascale that we are exploring from Europe.
Mont-Blanc continues to be a most exciting initiative, facing great challenges, in the promise of great rewards. Please, continue to follow our progress and visit us in Denver!
