High Performance Computing with Altitude: SC’16 Begins Tomorrow!

As readers may know, VMware has had a presence in the EMC booth for the last several years at Supercomputing, the HPC community’s largest annual ACM/IEEE conference and exhibition. With the fusion of Dell and EMC into DellEMC and with VMware now under the Dell Technologies umbrella, I am very pleased that we will have two […]

Performance of RDMA and HPC Applications in VMs using FDR InfiniBand on VMware vSphere

Customers often ask whether InfiniBand (IB) can be used with vSphere. The short answer is, yes. VM Direct Path I/O (passthrough) allows InfiniBand cards to be made directly visible within a virtual machine so the guest operating system can directly access the device. With this approach, no ESX-specific driver is required — just the hardware […]

VMware at Supercomputing 2015

SC ’15, the big, annual High Performance Computing (‘HPC’) conference, officially kicks off in Austin this evening with a gala opening of the conference exhibits. As we did last year, VMware has a demo booth within the EMC booth (#499) on the show floor. When I mentioned this to a customer recently, he cleverly asked […]

Running HPC Applications on vSphere using InfiniBand RDMA

Looking back on 2014, this was the year in which we made significant strides in assessing and addressing High Performance Computing (HPC) performance on vSphere. We’ve shown that throughput or task-parallel applications can be run  with only small or negligible performance degradations (usually well under 5%) when virtualized — a fact that the HPC community […]

Supercomputing ’14 Begins: Laissez les bon temps rouler!

  SC’14, the big, annual High Performance Computing (HPC) conference officially kicks off in New Orleans this evening with the opening of the exhibits. Workshops and tutorials have been held over the weekend as well: I gave a keynote presentation on Sunday at the 4th International Workshop on Network-aware Data Management (NDM’14), titled RDMA in […]

High Performance Computing (HPC) Update

Our HPC effort at VMware has been very active in recent months, and we have lots of information to share– including new performance results. Rather than cramming all of that content into a single mega blog entry, I’ve decided instead to give a preview here of some of the most significant developments. I will then […]

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 […]

Paravirtual RDMA for Low Latency and Flexibility

The Office of the CTO has been exploring how to best enable application access to RDMA for those applications requiring the ultimate in high bandwidth, low-latency communication, which includes many HPC MPI applications as well as many scale-out databases and BigData approaches. Passthrough mode is the most straightforward way to enable guest-level RDMA. With passthrough […]

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 […]

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 […]
