The Top 10 Things I Liked about ISC15

Hello all!  My long over-due post on the Top 10 Things I liked about ISC15. Work, life, and health got in the way after the conference. I am caught up and ready to remember the good times in Frankfurt by listing my Top 10.


1. Women in HPC Workshop on Thursday afternoon
Now it’s not just because I was on one of the panels. It was a really good workshop! The technical presentations were very interesting. The lively discussion on diversity in HPC not only opened my eyes, but it also has opened up a lot of questions. I look forward to the continued discussion!


2. Catching up
I didn’t know Terry worked for HP now (great to see you!). Or that Paul was changing jobs, or that Mark was now at Dot Hill. I guess LinkedIn updates are not keeping me up to date. Great to see you all!


3. New friends
I know I am at risk for missing someone, but I will still name a few names: Toni, Alison, Nages, Anna, Patricia, Wendy, Brian. We had talked via email, but hadn’t gotten to know each other face-to-face. We had some great conversations and laughs at the Executive Lounge in the Marriott!


4. Technologies
I didn’t have much time to see booths other than my customer’s booths, so my opinion here may be a little skewed. But did you see the Smart City demo in Numascale’s booth? Great use of Big Data and compute power. NICE Software always shows great demos of modeling and simulation in the cloud – yes you can collaborate remotely in real-time!


5. Attendees
Congratulations ISC on breaking a record on the number of attendees!


6. Presentations
I was actively tweeting from Analyst Crossfire and Vendor Showdown. Lots of great sound bites. One of my favorites from Barry Bolding – “Everyone needs a Cray”. (Maybe you had to be there…)


7. Parties
I was a party-pooper this year opting for visiting with old and new friends. But there is one that I didn’t miss – its great at every ISC and SC – Beers-on-Bright.


8. My Roomie
As many of you know Lara and I are great friends, colleagues, partners, and marketers for this industry. After a long day of meetings, networking, and working, we still have the energy to chat and catch up. It’s a great way to end the day!


9. Germany – Did not Disappoint!
The food, old town, the weather, walking around. It was very nice.


10. On beyond Germany.
I visited Paris, Milan, and London before coming home. Great times, lots of pictures, and great food and wine!


As always, I want to hear your favorites. Feel free to add a comment on this post, on my website, or Twitter.

See you all in Austin!


The HPCAC Conference in Brazil

We had the first HPC Advisory Council conference in Brazil. Held together with the Sao Paulo University. We hosted around 70 HPC professionals and 50 students from the University.

The conference was sponsored by Inspur, NVIDIA, SGI, Supermicro and Newwald. InsideHPC covered the event and videos can be found on The presentations from the conference can be found on

For me it was my first visit in Brazil. Probably would be better to do it one month after (the world cup….) but still, was happy to be there. Great people, great food and increase usage of HPC for many applications.

I want to thank Alexandre Ramos from the University of Sao Paulo that helped us with organizing the conference.

HPC Advisory Council ISCnet FDR InfiniBand 56Gb/s World First Demonstration

The HPC Advisory Council, together with ISC, showcased the world’s first FDR 56Gb/s InfiniBand during the ISC’11 conference in Hamburg, Germany on June 20-22. The demonstration was part of the HPC Advisory Council activities of hosting and organizing new technology demonstrations at leading HPC conferences that demonstrate new solutions which will influence future HPC systems in term of performance, scalability and utilization. The 56Gb/s InfiniBand demonstration connected participating exhibitors on the ISC’11 showroom floor as part of the HPC Advisory Council ISCnet network. The ISCnet network provided organizations with fast interconnect connectivity between their booths on the show floor to demonstrate various HPC applications, and new developments and products.

The FDR InfiniBand network included dedicated and distributed clusters as well as a Lustre-based storage system. Multiple applications were demonstrated, including high-speed visualizations. The following HPC Council member organizations have contributed and are participated in the world’s first FDR 56Gb/s InfiniBand ISCnet demonstration: AMD, Corning Cable Systems, Dell, Fujitsu, HP, HPC Advisory Council, MEGWARE, Mellanox Technologies, Microsoft, OFS, Scalable Graphics, Supermicro and Xyratex.

I would like to thank all of the demo participants and you can see the network map below.




HPC Advisory Council Forms Worldwide 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.”


HPC|GPU special interest subgroup releasing first results for NVIDIA GPUDirect Technology

The new HPC|GPU subgroup has been working recently to create first best practices around the new technology from NVIDIA – GPUDirect. Here is some background on GPUDirect: the system architecture of a GPU-CPU server requires the CPU to initiate and manage memory transfers between the GPU and the network. The new GPUDirect technology enables Tesla and Fermi GPUs to transfer data to pinned system memory that a RDMA capable network is able to read and send without the involvement of the CPU in the data path. The result is an increase in overall system performance and efficiency by reducing the GPU to GPU communication latency (by 30% as was published by some vendors). The HPC|GPU subgroup is first to release benchmarks results of application using GPUDirect. The application that was chosen for the testing was Amber, a molecular dynamics software package. Testing with 8 nodes cluster demonstrated up to 33% performance increase using GPUDirect. If you want to read more – check out the HPC|GPU page –




HPC Applications Best Practices

Wanted to let you know that we have extended the high-performance applications best practices to:


1. Extend the applications performance, optimization and profiling guidelines to cover nearly 30 different applications, both commercial and open source –


2. We have added the first case using RoCE (RDMA over Converged Ethernet) to the performance, optimization and profiling guidelines page. It is under the same link as in item 1


3. New – installations guides – for those who asked to get a detailed description on where to get the application from, what is needed to be installed, how to install on a cluster, and how to actually run the application – it is now posted under the HPC|Works subgroup – We will be focusing on open source applications, which sometime it challenging to really find this info. At the moment we have installations guides for BQCD, Espresso and NAMD, and more will come in the near future.


If you would like to propose new applications to be covered under the performance, optimization and profiling guidelines, or to be added to the installations guides, please let us know via

Best regards,

New system arrived to our HPC center!

Recently we have added new systems into out HPC center, and you see the full list at

The newest system is the “Vesta” system (and you can see Pak Lui, the HPC Advisory Council HPC Center Manager  standing next to it in the picture below). Vesta consist of six Dell™ PowerEdge™ R815 nodes, each with four processors AMD Opteron 6172 (Magny-Cours) which mean 48 Cores per node and 288 cores for the entire system. The networking was provided by Mellanox, and we have plugged two adapters per node (Mellanox ConnectX®-2 40Gb/s InfiniBand adapters). All nodes are connected via Mellanox 36-Port 40Gb/s InfiniBand Switch. Furthermore, each node has 128 GB, 1333 MHz memory to make sure we can really get the highest performance from this system.


Microsoft has provided us with Windows HPC 2008 v3 preview, so we can check the performance gain versus v2 for example. The system is capable of dual boot – Windows and Linux, and is now available for testing. If you would like to get access, just fill the form on the URL above.
