In this podcast, the Radio Free HPC team looks at CloudHarmony, an online service that measures and compares cloud provider uptime. “At CloudHarmony, we simplify the comparison of cloud services by providing reliable and objective performance analysis, reports, commentary, metrics and tools.”
“100% Flash in the Datacenter? It won’t happen any time soon. Many (most?) tier one workloads will be moved to flash of course, but data is adding up so quickly that it’s highly unlikely you will be seeing a 100% datacenter any time soon. It will take a few years to have about 10/20% of data stored on flash and the rest will remain on huge hard disks (cheap 10+TB hard disks will soon be broadly available for example).”
Nimbix is a pure high performance computing (HPC) cloud built for volume, speed and simplicity. “We give people the tools and the processing power to solve their biggest, toughest problems. We give you the freedom to imagine new possibilities, to test the limits of reality, and to model the future. We keep you one step ahead of the compounding problems of processing speed and infrastructure costs. And best of all, we do it faster, better, and more economically. We give you instant access and simple interfaces. We give you options and control. It’s supercomputing made super human.”
Since 2011, ONS (responsible for planning and operating the Brazilian Electric Sector) has been using AWS to run daily simulations using complex mathematical models. The use of the MIT StarCluster toolkit makes running HPC on AWS much less complex and lets ONS provision a high performance cluster in less than 5 minutes.
Most IaaS (infrastructure as a service) vendors such as Rackspace, Amazon and Savvis use various virtualization technologies to manage the underlying hardware they build their offerings on. Unfortunately the virtualization technologies used vary from vendor to vendor and are sometimes kept secret. Therefore, the question about virtual machines versus physical machines for high performance computing (HPC) applications is germane to any discussion of HPC in the cloud.
