LynuxWorks, based in San Jose, Calif., said Monday its LynxSecure separation kernel went through 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.

“During our benchmark tests, we analyzed processor utilization in increasingly more complex conditions using larger loading levels,” said Ed Jacques, Computer Systems Engineer at JHU/APL. "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.”

“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.
