Virtualized High Performance Computing in 2014

As we complete another circuit around the sun, it’s time again to make some predictions about what we’ll see over the course of our next orbit. Since my work in the Office of the CTO focuses on High Performance (Technical) Computing, I’ll focus there. But before looking ahead, let’s take a minute to look back and see how I did with my predictions last year . 2013 Predictions Scorecard Last year, my predictions related to public cloud, private cloud, RDMA in the cloud, virtual machine evolution, and HPC acquisitions. My biggest “miss” was also my most specific prediction — that Amazon would announce RDMA support in 2013 in order to better support latency-sensitive MPI applications. They did not,...

Hadoop Performance on vSphere 5.1

Hadoop Performance on vSphere 5.1

We’ve just published a third Hadoop performance paper, written by VMware performance expert Jeff Buell, which looks in detail at the relative performance of a bare-metal 32-node Hadoop cluster compared to a range of virtual clusters with up to 128 VMs. The executive summary is that while we saw a 13% performance degradation in a head-to-head comparison of a 32-node physical cluster against a 32-VM virtual cluster (one VM per host) running on the same hardware and running the same tests, virtualized performance can be increased significantly — to the point where virtualized Hadoop actually runs a bit faster than physical — by increasing the number of VMs per host. We’ve seen this effect before with Hadoop...

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...

Low Latency on vSphere at VMworld 2012

September 19, 2012
By

I was excited to have one of our partners, Mellanox, extend a special invitation for me to speak at their Expo booth during VMworld 2012 in San Francisco. They had allocated a 30 minute slot for a Theater Presentation and promoted my presentation via nice giveaways and postcards distributed in nearby VMworld hotels. I used this opportunity to reiterate some of the messages from the OpenFabrics Alliance Workshop in Monterey in March 2012 and to report on further progress with the Office of the CTO’s explorations into supporting RDMA at various levels in the vSphere ESXi hypervisor. In the first section of the presentation, I highlighted various use cases for RDMA...

Availability in a Software-Defined Datacenter

September 6, 2012
By

Last week, VMware hosted one of its most exciting VMworld conferences to date. The keynotes emphasized a bold vision for the future of IT: the software-defined datacenter (SDDC) . The SDDC is the datacenter where the infrastructure, including compute, storage, and networking, has been virtualized and fully automated by software, thus enabling IT to be delivered as a service. As Steve Herrod summarized in his Day 1 keynote – the SDDC is based on the ability to abstract applications from the underlying infrastructure, pool physical resources into shared logical resources, and automate IT operations.

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.
