Virtualized High Performance Computing (HPC) at VMworld 2013

August 19, 2013
By

It’s been a busy few months on the HPC front here at VMware. I’ve been spending increasing amounts of time answering questions from our field people and talking with customers about the benefits of using virtualization and cloud technologies for HPC workloads. The two hottest application areas are clearly Life Sciences and Electronic Design Automation (EDA), with Financial Services as a third area where serious interest is starting to ramp. Customers in these sectors are actively evaluating or deploying HPC solutions based on VMware technology. Some of this work will be presented at VMworld 2013 August 25-29 in San Francisco. Here are the talks that will be of special interest to organizations whose job mixes include the technical, scientific or engineering...

2013 Predictions: When Worlds Collide

2013 Predictions: When Worlds Collide

It’s time again to dust off the crystal ball, cast the yarrow sticks, read the tea leaves, and share some thoughts about where the IT world is heading over the next twelve months and beyond. Because my focus at VMware is on High Performance Computing (HPC), I’ll confine my prognostications primarily to the growing area of overlap between mainstream Enterprise Computing and HPC — places where each world can benefit from the other in important ways. Before I start, let’s get one no-brainer prediction out of the way: 2012 will be remembered for Nicira , and not Nibiru . Yes, software-defined networking ( SDN ) will trump planetary collisions and the...

Centralizing HPC Compute Resources using Private Cloud

December 5, 2012
By

I met recently with a group of academic CIOs and IT Directors in Denver to talk about how virtualization and private cloud technologies can help lower the barriers to adopting a centralized approach to delivering HPC resources in an academic environment. Of course, the barriers and concerns — losing control of resources, fear of not getting ones “fair share” in a shared facility, being forced into a standardized and sub-optimal software environment, etc.  – are relevant outside of academia as well. Because the topic is of broad interest, I’ve published the slides in SlideRocket and added an audio track that explains why virtualization should not be viewed simply as a tax one pays to move into a cloud environment, but rather as an approach...

HPC Performance in the Cloud: Status and Future Prospects

HPC Performance in the Cloud: Status and Future Prospects

I spoke last week at ISC Cloud 2012 in Mannheim, Germany about the performance of HPC applications in the cloud, citing results from several studies. I have summarized the talk below and my PDF slide deck is available here . For full details of ISC Cloud 2012, I recommend the coverage at  HPC in the Cloud . I gave my talk to share some specific data about HPC performance in virtual environments, but I first described what new capabilities can be gained by virtualizing an HPC environment. I felt this was necessary because in HPC discussions it is often the case that...

High Performance Computing with vSphere 5.1

We just announced a pile of new vSphere features at VMworld 2012 in San Francisco this week so I thought I’d take a few moments to describe several of those capabilities that will be of particular interest to High Performance Computing customers.

The Case for IT Convergence

July 6, 2012
By

I gave a talk recently at the HPC Advisory  Council Workshop at the International Supercomputing Conference ( ISC ’12) in Hamburg. The main purpose of the presentation, which was titled Ultra-low Latency in the Cloud: How low can we go?,  was to share our InfiniBand performance results with the HPC community to begin to address the question of whether cloud computing can be useful for more demanding types of applications than the throughput-oriented technical workloads that are known to run well in a virtualized cloud environment. (The short answer is we believe it can.) Before I presented our performance results, I spent the first part of the talk explaining what I see as an...
