What’s Trending in Flings – Third Quarter 2015

As the VMware Flings Program Manager, it’s been great watching the program grow and see the wonderful feedback and reactions we get from customers. As the program has matured, we have gathered valuable metrics and are seeing interesting trends. We want to share that success with you, and keep you up-to-date regarding the newest and […]

Tuning ESXi for NFV Workloads

Network Functions Virtualization (NFV) enables the efficiency and agility benefits that come from untethering network functions from proprietary appliances and moving them to a virtualized infrastructure running over hypervisors and COTS hardware. Enterprise IT departments have been realizing such benefits for a number of years but the telecommunications environment brings new workloads with different requirements. The vSphere ESXi hypervisor provides […]

Virtualized High Performance Computing (HPC) at VMworld 2013

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 […]

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 […]

Virtualization, Italian Style

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.

vSphere 5: vNUMA paper now available

I promised in the blog post vNUMA: What it is and why it matters to share the full research paper with you when it became available. It can now be downloaded here. If you find the paper useful, please click to give it a star rating on that same page. As a reminder, here is […]

Virtualizing Big Data

Analysis of large-scale, often unstructured data is becoming increasingly important within both the Enterprise and the HPC community. This is perhaps one of the most apparent areas where the convergence of HPC and Enterprise requirements can be seen as the tools and algorithmic approaches required are often the same or very similar. I imagine, for […]

vNUMA: What it is and why it matters

In vSphere 5, we introduced vNUMA which allows interested guest operating systems to see that they are running on a NUMA (Non Uniform Memory Architecture) topology. For those not familar, here is a one-diagram NUMA explanation. As you can see, in the UMA case, the cost of accessing a particular memory address is the same […]

Summer of RDMA

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 […]
