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 […]

Virtualized HPC at Johns Hopkins Applied Physics Laboratory

Johns Hopkins University Applied Physics Laboratory (JHUAPL) has deployed a virtualized HPC solution on vSphere to run Monte Carlo simulations for the US Air Force. The idea was conceived and implemented by Edmond DeMattia at JHUAPL, and has been presented by Edmond and his colleague Michael Chinn at two VMworld conferences. We now have a white […]

GPGPU Computing with the nVidia K80 on VMware vSphere 6

[UPDATE: Feb, 2017: This blog entry has been updated to correct an error. To use advanced features like passthrough of large-BAR PCI devices, you must use a UEFI-enabled VM and guest OS.]   As customer interest in running HPC workloads on vSphere continues to increase, I’ve been receiving more questions about whether compute accelerators like […]

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 […]
