Those of you who have been reading my blog or listening to my various conference talks since I arrived at VMware last year know I have been arguing there is an important convergence underway between HPC and Enterprise IT requirements. In large part this is being driven by fundamental changes within Enterprise computing, specifically the move towards massive, horizontally-scaled infrastructure to deliver scalable services externally in the cloud or internally for strategic business advantage.
As you’d expect with my background, I’ve been looking at this from an HPC perspective, noting that the HPC community has been heavily invested for decades in scale-out cluster provisioning, management, monitoring, etc. And they have built expertise around hardware architectures to support scale-out computing, most particularly in the design of high-performance interconnect fabrics. These fabrics support the link-level bandwidths and latencies as well as the fabric bisection bandwidths needed to enable both highly-parallel computations as well as ubiquitous, high-performance access to shared resources like storage in a high-scale environment.
Imagine my delight when I came across a position paper espousing the same view titled It’s Time for Low Latency by Stephen Rumble, Ryan Stutsman, Mendel Rosenblum, and John Ousterhout that was presented at HotOS ’11 (http://www.scs.stanford.edu/~rumble/papers/latency_hotos11.pdf). And what a coincidence that the paper’s third author is none other than VMware’s well known co-founder, Mendel Rosenblum.
The paper approaches the importance of low latency from an Enterprise perspective, citing numerous reasons why a high-performance interconnect will benefit the modern datacenter and its applications. The paper is styled as a call to action for OS and system designers to heed the need to pay significant attention to making low latency communication available to current and emerging Enterprise applications, including Big Data applications.
The paper is a quick read and well worth the time.

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.
About two years ago, we initiated an investigation into new market opportunities for Xyratex. During this investigation we learned that the High Performance Computing (HPC) market was a dynamic market opportunity with a substantial need for better data storage design. We also discovered that the way data storage was being implemented at many of these supercomputing sites was unduly complicated in terms of initial installation, performance optimization and ongoing management. Users had to contend with days and possibly weeks of tweaking to get the system up and running stably. After this initial installation period was complete, the ongoing management of the system was also complicated by varied and disjointed system and management tools. Often administrators would have to contend with debug scenarios that required the application of scarce resources and ultimately the sub optimal performance of their HPC system.
We were surprised at these findings and saw a lot of opportunity for Xyratex to deliver new innovation in terms of performance, availability and ease of management. Xyratex decided to make a significant investment in addressing these needs. This investment included the acquisition of ClusterStor, but didn’t stop there. We have nearly 150 engineers working on the program and we developed a brand new high density application platform that is optimized for performance and availability. Finally, we developed a new management framework that addresses the complexity issues we found in the management of HPC storage clusters.
Today, we announced the ClusterStor™ 3000. This release is the result of that significant investment over the last two years and provides our partners with an innovative new solution for the HPC marketplace. We leveraged our core capabilities, in data storage subsystem design and the Lustre expertise we obtained in the ClusterStor acquisition last year, to develop an HPC solution that provides the best-in-class performance, scale out architecture and unprecedented ease of management.

We are proud to announce the release of SPM.Python version 3.110505, and wish to acknowledge the generous support of the HPC Advisory Council in providing access to GPU servers to validate and stress test of our solution.
SPM.Python is a scalable parallel version of the popular Python language. Showcased as a disruptive technology at Supercomputing 2010 and highlighted on StartUp Row at PyCON 2011, it enables users to exploit parallelism across servers, cores and GPUs in a fault tolerant manner.
Using resources at the HPC Advisory Council High Performance Center, we were able to conduct around 20,000 different sets of experiments; most were designed to fail in order to
validate the failure recovery and self-cleaning capabilities of SPM.Python.
With this release, users may launch any standalone application in parallel and in a manner that inherits fault tolerance from SPM.Python, thus freeing the developers to focus on their core application while maximizing utilization of resources and minimizing runtime costs.
This week we have held the 2nd HPC Advisory Council Swiss workshop in Lugano Switzerland. Nearly 140 attendees participated in the 3-days workshop, 18 sponsors sponsored the workshop, and it was covered by 3 media sponsors. Many videos from the workshop can be found for example on InsideHPC web site (www.insideHPC.com). All of the presentation can be found on the workshop web page – http://www.hpcadvisorycouncil.com/events/2011/switzerland_workshop/.
The workshop was very successful. We had presentations on various topics – MPI, networking, GPUs and many other topics, hands-on sessions on networking and Lustre, and overview on activities at various HPC centers around the world.
I would like to thank all the speakers, the attendees and the sponsors. Now we are getting ready to the next workshop in Germany as part of ISC’11 – http://www.hpcadvisorycouncil.com/events/2011/european_workshop/. I encourage you to join us at the workshop. Folks interested in sponsoring or presenting – please drop me a note at firstname.lastname@example.org.
All the best,
Gilad, HPC Advisory Council Chairman
Student teams are encouraged to submit proposals to build high performance computing clusters on the convention center floor in real time and push their applications to the limit to win bragging rights as the world’s best. Submissions are now open for the fifth annual Student Cluster Competition (SCC) for at the SC11 conference held in Seattle, WA on Nov. 12 – 18, 2011. Please note that the deadline for teams to enter contest is April 15
The competition pits six teams of undergraduates against one another to see who can build and configure a cluster in 46 hours that accomplishes the most work using “real world” computational codes in the least amount of time. In addition to time constraints, students must work within the parameters of the designated system and power configurations, and use open-source software to solve the applications provided to them.
In addition to showcasing the power of current-generation clusters, one of SCC’s primary goals is to demonstrate to companies and supercomputing labs that the best high performance computing (HPC) candidates might be as close as the university next door. Through the final selection process, the SCC committee focuses on recruiting the best high performance computing talent to compete each year.
Student teams may now submit their applications at the SC11 Submissions Site – https://submissions.supercomputing.org/ ; the SCC deadline is April 15, 2011. Teams will find more information and may refer to a sample Student Cluster Competition submission form.
