Johns Hopkins University Applied Physics Laboratory Performs Successful Investigation of LynuxWorks’ LynxSecure for Real-Time Applications

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) March 22, 2010 -- LynuxWorks™, Inc., a world leader in the embedded software market, today announced that its LynxSecure separation kernel was independently tested with a series of performance tests at The Johns Hopkins University Applied Physics Laboratory (JHU/APL), to help assess the use of separation kernels for future real-time, mission-critical systems.

JHU/APL ran benchmarks on LynxSecure, using a Linux operating system as the guest. The results showed good performance and stability for LynxSecure with a range of common benchmarks, including LMbench and the iPerf networking suite. The tests also demonstrated the effectiveness of LynxSecure’s multi-core performance. When used with multi-core processors, LynxSecure can run multiple operating systems and applications on each core, or bind applications and operating systems to specific cores offering the utmost flexibility in system design and performance utilization.

“During our benchmark tests, we analyzed processor utilization in increasingly more complex conditions using larger loading levels,” said Ed Jacques, Computer Systems Engineer at The Johns Hopkins University Applied Physics Laboratory. "Even at high loading levels, we found that the system performance remained strong. Processor utilization was close to what was observed when running the same environment on the same hardware without LynxSecure.”

JHU/APL also investigated the robustness of the LynxSecure separation kernel, which supports a unified processing environment with multiple security domains. The suite of tests included a multifaceted application environment, which helped to demonstrate that LynxSecure running on Intel VT-x enabled hardware can support such complex environments with negligible impact on overall performance.

LynxSecure is a separation kernel and embedded hypervisor designed to be used in secure real-time environments to the highest levels of security. The small separation kernel part of LynxSecure maintains the real-time determinism and security separation including the definition of secure information flow policies between applications running on a single piece of embedded hardware.

“The JHU/APL benchmark tests have independently confirmed what we have known all along, which is that the LynxSecure separation kernel has the performance required to support multiple security domains on a single piece of hardware,” said Robert Day, vice president of marketing at LynuxWorks.
