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

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...

Ultra-low latency in the Cloud: How low can we go?

June 13, 2012
By

I’ll be speaking this weekend at the HPC Advisory Council European Conference 2012 in Hamburg, just prior to the International Supercomputing Conference ( ISC ’12 ), which runs from June 17-21st. If you will be attending either event and would like to talk about HPC and virtualization, send me an email — “simons” at the obvious place.

Virtualizing Science, Engineering, and Technical Applications at VMworld

June 5, 2012
By

I’ve talked to a lot of customers in the past year who have islands of unvirtualized infrastructure within their organizations. Examples include insurance companies running risk analyses, digital content creation companies rendering movie frames, electronic design companies running simulations of chip designs, life sciences organizations running a variety of genomics and other applications, and government agencies running security-related simulations and other workloads. If your organization runs such workloads and you are interested in hearing how they can be virtualized, consider voting for the following VMworld proposal. Public votes can be cast here (free registration required) and voting closes on June 8th. 1984 A self-service model for supporting engineering, scientific and other technical applications in a vCloud environment As the use...

Ultra-low latency on vSphere at VMworld 2012: Voice your Interest!

June 4, 2012
By

Low-latency communication is one area we’ve been exploring within the Office of the CTO as part of our efforts to enable new workloads to run well on the platform, including High Performance Computing (HPC) applications and scale-out Enterprise applications.  If you are interested in hearing about this topic at VMworld 2012, consider casting a vote for the two proposals listed below during the public voting period, which ends on June 8th. Vote here (free registration required). 1514 Ultra-low latency on vSphere: How low can we go? Low-latency applications are becoming more important in the Enterprise datacenter and for emerging workloads like High Performance Computing. As a response to this, the Office of the CTO is exploring several options to...

Video: Ultra-low latency on vSphere

April 9, 2012
By

As promised , Bhavesh’s talk at the OpenFabrics User and Developer Workshop is now available for your viewing pleasure. In it, I spend a few minutes talking about some of the findings from our upcoming InfiniBand paper, and then turn it over to Bhavesh who presents the bulk of the talk. The video is here .   Part of Bhavesh’s talk covers our interest in providing RDMA capabiltiies to guest operating system instances while maintaining the ability to vMotion (live migrate) such virtual machines. This is crucial if RDMA is going to gain wider acceptance in the modern, virtualized datacenter where the value of live migration has been repeatedly demonstrated.   From a technologist’s perspective, it was good...
