Mellanox HPC-X Framework Gains Marked Cross-Industry Adoption from HPC Market Leaders

Comprehensive HPC software suite enables highest applications performance and scalability

ISC High Performance 2015, Frankfurt, Germany – July 13, 2015 – Mellanox® Technologies, Ltd. (NASDAQ: MLNX), a leading supplier of end-to-end interconnect solutions for data center servers and storage systems, today announced continued industry adoption of the HPC-X™ Scalable Software Framework, a comprehensive software suite for high-performance computing environments, which provides enhancements to significantly increase the scalability and performance of message communications in the network, supporting MPI, PGAS/SHMEM and UPC.

Since its introduction in June of last year, the HPC-X Scalable Software Framework has achieved increasing adoption into the product portfolios of leading industry ISV and ecosystem partners, such as Altair, Bright Computing, BULL, SGI, Q-Leap Networks and many others.  

“HPC-X enables you to rapidly deploy and deliver maximum application performance,” said Damien Declat, director and head of High-Performance Computing competency centers at Atos. “We were able to achieve a significant 37 performance gain on Quantum Expresso at 43 nodes, and even more impressive was running at 196 nodes, we noted a 61 percent up-tick in performance, compared to other MPI middleware.”

“HPC-X has demonstrated exceptional performance improvements across leading commercial and open source HPC applications.”, said Scot Schultz, director, HPC and Technical Computing at Mellanox Technologies, “HPC-X includes native acceleration capabilities to allow anyone to rapidly realize the performance that was once being left on the table by using other commercially available MPI packages.”

“We are happy to be able to provide HPC-X to our customers”, said Lionel Gibbons, VP marketing at Bright Computing. “This full-featured HPC Software framework complements Bright Cluster Manager and enables applications to scale up to large clusters by improving on memory and latency related efficiencies.”

Mellanox HPC-X provides a unique value for customers to fully achieve maximum system efficiency, application performance and scalability by exploiting the underlying interconnect fabric’s acceleration capabilities.

“HPC-X unlocks the real potential of the application by providing transparent acceleration capabilities of the underlying hardware,” said Eric Lequiniou, director, High Performance Computing, at Altair. “HPC-X delivers maximum application performance without the cost or complexity of licensed third-party libraries. With HPC-X we have seen performance gains of 25 percent with Altair OptiStruct in as few as 24 nodes, and 25 percent increase in performance with RADIOSS at just 16 nodes using EDR InfiniBand versus older technologies”

The Weather Research and Forecasting (WRF) Model is a mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting needs. The latest performance results of HPC-X with Mellanox EDR 100Gb/s InfiniBand also demonstrates over 8 percent greater productivity at just 32 nodes (896 cores) with the WRF conus12km benchmark, versus other commercially available MPI products.

“Integrating HPC-X into the Qlustar MPI stack adds exceptional value for our customers,” said Roland Fehrenbacher, CEO, Q-Leap. “Our recent OpenFoam benchmarks have shown that even for node counts as small as 4, a significant performance boost of more than 10 percent can be achieved. HPC-X is an absolute must for many communication intensive applications.”

HPC-X provides complete communication libraries to support MPI, SHMEM and PGAS programming languages, as well as performance accelerators that take advantage of Mellanox's scalable interconnect solutions. HPC-X continues to provide support for other interconnect solutions as well, based on the Ethernet and InfiniBand standards.
