Voltaire unveils Open MPI Accelerator software

To enhance performance of Open MPI-based applications

Voltaire has introduced new Open MPI Accelerator (OMA) software that reportedly enhances the performance of Open MPI-based applications in server and storage environments.

According to Voltaire, the OMA works over any interconnect technology that works with Open MPI, including InfiniBand and 10 Gigabit Ethernet (10GbE). It enhances inter-node and intra-node communication by freeing up intra-node resources resulting in improved performance for HPC applications.

Voltaire has conducted tests with OMA and several other commercial HPC applications based on Open MPI. One of these tests revealed that OMA enhances performance of OpenFOAM tutorial by up to 28%.

The company said that OMA can be integrated with Open MPI and requires no tuning to achieve the desired performance.

Asaf Somekh, vice president of marketing at Voltaire, said: “In an economic climate of shrinking IT budgets, Voltaire OMA enables customers to get even greater performance out of their existing Open MPI-based infrastructures and delivers an almost immediate return on investment for intensive HPC environments.

Customers operating either InfiniBand or 10GbE for their server and storage connectivity can now use software to get an extra boost of performance for their business-critical applications.”
