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 […]

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 […]

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

[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.] Compute accelerators ¬†— whether they be GPUs, Intel Xeon Phi, or FPGAs — are increasingly common in HPC and so it is important […]
