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...

Consistent Auditing in the Cloud Era

November 13, 2012
By

With the growth of cloud computing and the increase of customers deploying workloads in hybrid clouds, having the ability to audit information in a standard way across multiple cloud platforms has come to the forefront. The good news is that a lot of work has already been done in this area. The DMTF addressed this need with a new initiative launched last year that looks at the ability to create open standards to federate and expose auditing data for cloud consumers. While it’s still early, I expect that over time this direction will give cloud consumers more confidence that their data is safe and that they’re getting what they paid for.

I’m in Fiuggi, Italy this week teaching a four-lecture course on Virtualization and High Peformance Computing as part of the Eighth International Summer School on Advanced Computer Architecture for High Performance and Embedded Systems ( ACACES 2012 ). I have about 70 students in the class, primarily from European countries.

PLDI and the Importance of Virtualization for Developers

June 22, 2012
By

My VMware colleague, Ole Agesen, recently gave a keynote at the Programming Language Design and Implementation (PLDI) conference in Beijing. PLDI is a forum where researchers, developers, educators, and practitioners exchange information on the latest practical and experimental work in the design and implementation of programming languages.

Video Interview: Josh Simons on Virtualization for HPC and Big Data

March 28, 2012
By

I sat down for an interview with William Wallace from insideHPC at the OpenFabrics Alliance User and Developer Workshop in Monterey yesterday in which we talked about low latency and RDMA for the Enterprise and for HPC and the importance of Big Data to VMware. The video (running time 10:13) is here .

Acaces ’12: Virtualization and High Performance Computing

February 27, 2012
By

I’ll be teaching a course titled Virtualization and High Performance Computing at the Eighth International Summer School on Advanced Computer Architecture and Compilation for High-Performance and Embedded Systems (ACACES) the week of July 9th in Fiuggi, Italy. Full details on the summer school are here .   Here is the abstract for the class:   “System-level virtualization is widely used in commercial enterprise environments — close to half of the workloads running in the world today run within virtual machines. And yet virtualization has not to date played any significant role in High Performance Computing despite the fact that virtualization technology can offer some unique advantages for HPC.   While the rise of cloud computing and its promise of computing on demand has...

Summer of RDMA

July 8, 2011
By

Those involved in HPC understand the need for low latency communication for many parallel distributed applications and for those applications whose storage requirements generate lots of small-message traffic. But it would be a mistake to assume low latency is an HPC-only issue. Why? Well, for two reasons. First, because as enterprise software architectures become more horizontally scaled (also referred to as “scale-out”) the performance of the link connecting communicating endpoints becomes much more of a first-class determinant of overall application performance, much like in HPC. Middleware examples include memcached , vFabric GemFire , and Hadoop . Oracle’s Exadata and Exalogic products are another example in that these appliances use an InfiniBand interconnect (the most popular high-speed interconnect technology...

Let’s get logical – the case for network virtualization

Let’s get logical – the case for network virtualization

In my last post , I hinted about the changes happening in the data center, especially with respect to networking and security architectures and deployments. To say that there are transformational changes going on in the industry in this area, is an understatement – the premier networking event Interop goes live this week in Las Vegas, and will showcase some of these trends. One of sessions of interest is hosted by the recently formed Open Networking Foundation, which will also hold an informational session Wednesday, May 11th at 11 – 11:45 to highlight the ONF vision and the future of Software Defined Networking (SDN). The rampant adoption of server virtualization and consolidation, the emergence of server hosted desktops, along...

Our Joint VMware / AMAX HPC Collaboration

Our Joint VMware / AMAX HPC Collaboration

I am excited we have now started our joint HPC exploration with our partner, AMAX . Based on an initial meeting on the show floor at VMworld in San Francisco last year, we decided to work together to examine several aspects of virtualized HPC of mutual interest. Areas where we see converging requirements between HPC and Enterprise customers are of particular interest to VMware as an Enterprise software company looking at broader markets and to AMAX as a dynamic computing solutions provider to HPC and Enterprise , and now Cloud customers. We are starting with Hadoop since scale-out data analytics is rapidly becoming an important workload in the Enterprise while Data Intensive Computing is simultaneously rising...
