Gartner Cool Vendor 2017 image

San Francisco, CA — Rescale, the turnkey platform provider in cloud high performance computing, today announced that it has been named a “Cool Vendor” based on the May 2017 report “Cool Vendors in Cloud Infrastructure, 2017” by leading industry analyst firm Gartner.

The report makes recommendations for infrastructure and operations (I&O) leaders seeking to modernize and exploit more agile solutions, including the following:

  • “I&O leaders should examine these Cool Vendors closely and leverage the opportunities that they provide.”
  • “As enterprises grapple with the right mix of on-premises, off-premises and native cloud, choosing a cloud infrastructure vendor becomes more critical.”

We have made a number of blog posts over the years where we have run some MPI microbenchmarks against the offerings from the major public cloud providers. All of these providers have made a number of networking improvements during this time so we thought it would be useful to rerun these microbenchmarks against the latest generation of VMs. In particular, AWS has released a new version of “Enhanced Networking” that supports up to 20Gbps, and Azure has released the H-series family of VMs which offers virtualized FDR InfiniBand.

My colleague Irwen recently ran the point-to-point latency (osu_latency) and bisection bandwidth (osu_bibw) tests from the OSU Microbenchmarks library (version 5.3.2) against a number of different VM types from Google Compute Engine. For consistency, we’ll use the same library here with Azure and AWS.  The table below includes the best performing machine from Irwen’s post: the n1-highmem-32. The c4.8xlarge represents an AWS VM type from the previous Enhanced Networking generation and the newer m4.32xlarge VM is running the newer version of Enhanced Networking.

In the table below, we list the averaged results over 3 trials. A new pair of VMs were  provisioned from scratch for each trial:

0-byte Latency (us) 1MB bisection bandwidth (MB/s)
GCE (n1-highmem-32) 41.04 1076
AWS (c4.8xlarge) 37.07 1176
AWS (m4.32xlarge) 32.43 1152
Azure (H16r) 2.63 10807

As you might expect, the Azure H-series VMs seriously outpace the non-InfiniBand equipped competition in these tests. One of the frequent criticisms levied against using the public cloud for HPC is that networking performance is not up to the task of running a tightly-coupled workload. Microsoft’s Azure has shown that it is possible to run a virtualized high-performance networking fabric at hyperscale.

That said, while this is interesting from a raw networking performance perspective, it is important to avoid putting too much stock into synthetic benchmarks like this. Application benchmarks are generally a much better representation of real-world performance. It is certainly possible to achieve strong scaling with some CFD solvers with virtualized 10GigE. AWS has published STAR-CCM+ benchmarks showing close to linear scaling on a 16M cell model on runs up to 700 MPI processes. Microsoft has also published some STAR-CCM+ benchmarks showing close to linear scaling on up to 1,024 MPI processes with an older generation of InfiniBand equipped VMs (note that this is not an apples-to-apples comparison because Microsoft used a larger 100M cell model in their tests). It’s also important to highlight that specialized networking fabric typically comes at a higher price point. Additionally, keep in mind is that network speed is just one dimension of performance. Disk IO, RAM, CPU core count and generation, as well as the type of simulation and model size all need to be taken into consideration when making a decision about what hardware profiles to use. One of the advantages of using a multi-cloud platform like Rescale’s ScaleX Platform is that it makes it easy to run benchmarks and moreover, enterprise HPC workloads, across a variety of hardware configurations by simply changing the core type in your job submission request.

Finally, it is impressive to note how far things have come from the original Magellan report. There is a fierce battle going on right now between the public cloud heavyweights and we are starting to see hardware refresh cycles including not only high-performance interconnect but also modern CPU generations (Skylake) as well as GPU and FPGA availability at large scale. The “commodity” public cloud is increasingly viable for a growing number of HPC workloads.

San Francisco, CA — Rescale and DYNAmore are excited to announce that hourly, on-demand licenses of the popular finite element analysis (FEA) software LS-DYNA are now available in Europe on ScaleX™ Enterprise, Rescale’s enterprise cloud platform for big compute. The joint launch builds on the success of on-demand licensing in the United States, which accounts for 99% of LS-DYNA jobs on ScaleX in that country. DYNAmore, LS-DYNA’s European distributor, will take care of orders and billing, while Rescale will deliver the software on its cloud platform.

Rescale provides ScaleX, a cloud computing platform for simulation and other software that require high-performance computing (HPC). Over 200 third-party software packages, including LS-DYNA, are integrated onto the ScaleX platform, which users can leverage on the cloud via an intuitive SaaS graphical user interface. Rescale partners with major public cloud providers, including AWS and Microsoft Azure, to allow users to run simulations on a global network of the latest HPC hardware.

LS-DYNA, one of the most popular software packages on the ScaleX platform, was previously available to European customers under a “bring-your-own-license (BYOL)” model that permitted customers to use their annual or paid-up licenses on the Rescale platform. With the addition of on-demand licensing, European LS-DYNA customers can now instantly purchase hourly licenses on the cloud to meet their variable simulation requirements and pay by the hour for the licenses they use. In conjunction with Rescale’s multi-cloud network of on-demand HPC hardware, on-demand licenses will allow European LS-DYNA customers to fully leverage the elasticity of the cloud. “Engineers at European enterprises now have the freedom to scale out their LS-DYNA simulations in the blink of an eye, giving their organizations the IT agility that directly corresponds with ROI,” said Joris Poort, Rescale’s CEO.

DYNAmore’s Software Solutions Manager Uli Göhner anticipates the news will boost LS-DYNA sales in Europe as the software licenses become more accessible and easy to purchase. “We already have a lot of requests from our existing customer base for short term HPC resources. Our flexible licensing strategy allows customers to lease additional licenses for a short term or to purchase licenses on a pay-per-use basis. This new licensing option was implemented especially for our LS-DYNA cloud offering and allows our customers to use their HPC resources effectively.”

Rescale is a Gold Sponsor of the 11th European LS-DYNA Conference in Salzburg, Austria on May 9-11, 2017. Visit the Rescale booth for a live demo of how to buy on-demand licenses on ScaleX.
