Come See MBA Sciences at SC’10

MBA Sciences recently joined the HPC Advisory Council, and we are pleased to announce the selection of their SPM.Python product as an SC10 Disruptive Technology (booth 1046C). SPM.Python is a scalable, parallel version of the Python language designed to enable a broad range of users to exploit parallelism.

I will be talking at the Intel Parallel Programming Talk on Intel Software Network TV in Show #97 Tuesday, November 16, 2010
8:30am Pacific (Live from SC10 in New Orleans). http://software.intel.com/en-us/articles/parallel-programming-talk

Looking forward to see you all at SC’10,

Minesh B. Amin, MBA Sciences founder and CEO

HPC Advisory Council Forms Worldwide Centers of Excellence

This week we announced the formation of the HPC Advisory Council Centers of Excellence. The HPC Advisory Council Centers of Excellence will provide local support for the HPC Advisory Council’s programs, local workshops and conferences, as well as host local computing centers that can be used to extend such activities.

“We are pleased to be named as one the inaugural HPC Advisory Council’s Centers of Excellence, covering HPC research, outreach and educational activities within Europe,” said Hussein Nasser El-Harake at the Swiss National Supercomputing Centre who serves as the Director of the HPC Advisory Council Center of Excellence in Switzerland. “As part of the HPC Advisory Council’s Center of Excellence, we look forward to advancing awareness of the beneficial capabilities of HPC to new users.”

Scientific Discovery through Advanced Computing Conference, July 2010

Each year, scientists participating in the Scientific Discovery through Advanced Computing Program (SciDAC), along with other researchers from the computational science community gather at the annual SciDAC conference to present scientific results, discuss new technologies and discover new approaches to collaboration. The SciDAC 2010 Conference is being held this week in Chattanooga, Tennessee. Thomas Zacharia, Oak Ridge National Laboratory, chairs the conference this year.

I participated in the first 2 days of SciDAC. While the weather there is not ideal to say the least…  I have enjoyed the presentations and discussions.  The Undersecretary Steven Koonin (undersecretary for science, department of energy) commented on DoE future goals – reducing Oil consumption in transportation by 35%, reducing greenhouse gas emissions 17% by 2020, and 83% by 2050, maintain technical base and exploit simulation capabilities.

Many of the discussions were on Exascale computing – what is needed to be done in order to get there – systems, applications etc, with the goal to have the first system by 2018. Our HPC|Scale subgroup will try to help make the right steps toward this goal with exploration and experiments. I hope to report soon on the subgroup progress.

International Supercomputing Conference 2010

The second biggest HPC show will start next week, and I am now on a United flight from San Francisco to Germany on my way to the conference. On Sunday we will do the HPC Advisory Council European workshop, the second workshop of the year (3 more to come – TeraGrid, HPC China and MEW UK). For the workshop we have gathered some interesting HPC people from around the world – Richard Graham and Steve Poole from Oak Ridge National Laboratory US, Norbert Eicker from the Jülich Supercomputing Centre Germany, Tor Skeie from Simula Research Laboratory Norway, and Abhishek Das from C-DAC India. We will also host interesting talks on HPC in cloud computing, virtualization and HPC, application best practices and more. I will make sure to capture the highlights from the day and share it here.

ISC’10 is also the place where the Top500 list is being published. Published twice a year (ISC and SC), the Top500 list rank the 500 fastest supercomputers in the world. Why is it important for us? Because it can give us indications on trends in the HPC world, capabilities and usage models. It is also a great tool for making predications on when we will see the first ExaScale system etc.

And last but not least, the HPC Advisory Council will give the 2009-2010 awards in 4 categories in the closing session of ISC – Thursday at 1pm Germany time. If you are planning to be in Germany feel free to join us at the workshop, or be there for the award ceremony. Or just drop by and say hello…

Evaporative immersion

Hi,

I work as a Thermal Application Engineer in 3M’s Electronic Markets Materials Division.  For more than 50 years, my group has made fluorochemical heat transfer fluids that have been used for immersion cooling of high value electronics.  Some are familiar with the various Fluorinert™-cooled Cray supercomputers but our fluids are also used in tens of thousands of immersion cooled traction inverters and a variety of military platforms.  

Evaporative immersion is arguably one of the most efficient ways to implement fluids like ours for cooling electronics.  Heat sources on a PCB immersed in the fluid cause that fluid to boil.  This captures all heat and allows it to be transferred efficiently to air or water via a secondary condenser.  Historically, immersion systems of this type have used sealed pressure vessels with hermetic electrical connections and are evacuated and filled much like refrigeration systems.  Because it can be costly to create such an enclosure for computational electronics with a lot of IO, Engineers often dismiss the idea of immersion in the context of commodity datacenter equipment.  The concept we are promoting (see attached) eliminates these complexities.  Other advantages are summarized below.

- All server level and most rack level cooling hardware are eliminated
     – reduced environmental impact (landfill)
     – simplified server/rack design 
     - reduced cooling equipment cost 
     - no moving parts to fail or leak

- Essentially no thermal limit on server power density 
     - 4 kW/liter (4 MW/m3) has been demonstrated (>100X typical air cooled and >25X typical supercomputer) 
    -  possibility for reductions in raw material usage (PCB, etc) 

- Intrinsic fire protection

We are demonstrating this concept with real computing hardware but because we are using off-the-shelf air cooled components, the power density merits of this technology cannot be realized and the demonstration will lack luster.

We seek partners with challenging-to-cool hardware and an interest in exploring this technology.  We believe it could be a transformative technology enabling the next-generation power density goals of the HPC industry.

MPI optimizations using the HPC Advisory Council HPC Center

Recently we have been working on performance optimizations for Platform MPI for the Swedish Meteorological and Hydrological Institute (SMHI).

The application we were testing the MPI optimization for is the “SMHI RCO application” which can use the ScaliMPI or the PMPI (Platform MPI).

At first we have tested the application performance on Scali MPI and Platform MPI and achieved the following results (using 144 ranks, 18 hosts 8 ranks each on the “Helios” cluster). The original Scali MPI based run was 474 seconds and the original Platform-MPI was 550 seconds.

We have modified the Platform MPI and the optimized results with Platform MPI demonstrated 450 seconds for the application run.

We want to thank the HPC Advisory Council for providing the resources for us to evaluate our optimizations and provide a better solution for the customer.

Regards,
Perry Schmidt
