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

As customer interest in running HPC workloads on vSphere continues to increase, I’ve been receiving more questions about whether compute accelerators like the nVidia K80 or Intel Xeon Phi can be used with vSphere VMs.   The answer is that while VMware supports the VM Direct Path I/O feature (i.e., passthrough mode) that allows PCI […]

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 […]

Office of the CTO at VMworld Europe

With VMworld US securely under our belt, VMware’s Office of the CTO has been forging forward with preparations for VMworld Europe this month. Will we see you in Barcelona? If the answer is yes, take a few minutes to review where to find us on site. VMware’s Office of the CTO Booth: Don’t forget to swing by […]

Using nVidia GPGPU Compute Acceleration with ESX 6.0

As was mentioned in a previous blog post, accelerator cards are becoming increasingly common in HPC environments and so it is important that we assess the performance of such cards with ESX. Thank you very much to Na Zhang for all of her work on the following. In this post, we share the results of […]

Research and High Performance Computing at VMworld US

There will be a High Performance Computing in Research and Data Analytics Roundtable session held on Monday evening in conjunction with VMworld US in San Francisco. This session is a part of the Government & Education Roundtable Series and is intended primarily for those customers. Seating is limited and registration is required. Registration is here. […]

Using the Intel Xeon Phi Compute Accelerator with ESX 6.0

Compute accelerators  — whether they be GPUs, Intel Xeon Phi, or FPGAs — are increasingly common in HPC and so it is important that we assess the use of such technologies from within VMware vSphere® as part of our efforts to virtualize research computing and other HPC environments. Last year when I tested Intel Xeon […]

What Impact Can Virtualization Have on the Field of Research Computing?

Challenges for IT supporting research computing environments What is most important to an IT department supporting university research? Based on conversations with many of our customers, we have repeatedly heard the following: Satisfying the varied and sometimes conflicting requirements of different research groups, which may include compliance issues for bioinformatics research Showing the value of […]

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 […]
