Opal-RT adds InfiniBand support for real-time simulation, HIL testing

Opal-RT Technologies Inc. which specializes in real-time simulation and hardware-in-the-loop (HIL) testing for automotive and other technologies, has added support for InfiniBand, the switched-fabric-based open standard for intercomputer communications.

Opal-RT’s InfiniBand interface facilitates communication between real-time simulators at up to 300 Mbytes/s, according to Jean Belanger, president and chief technical officer. “This newly achieved throughput is over five times faster than IEEE 1394b FireWire, and reaches an effective communication throughput comparable to a shared-memory interface,” he said. “We expect to see wide use of the InfiniBand interconnect in automotive HIL applications, especially in vehicle system level simulation and detailed motor and power electronics simulation."
