Concurrent reports that its commercial, real-time Linux implementation for multi-processor AMD Opteron processors was selected by a Toshiba engineering team designing multi-function peripherals with built-in laser printers. Toshiba engineers will use the “RedHawk” real-time OS for time-critical simulation of toner particle motion, the vendor said.

Toshiba purchased several of Concurrent's dual-Opteron based iHawk systems for a numerical modeling application, Concurrent said. The systems will be used to model the behavior of toner and ferrite particles as the printer's magnetic roller rotates, in order to determine optimum roller speed, magnetic field strength, and particle size and distribution. The application requires a “dynamic calculation interval” below 100 nanoseconds, according to Concurrent.

Concurrent's RedHawk Linux OS is based on Red Hat, and uses processor shielding technology aimed at guaranteeing sub-millisecond response times on multi-core Opteron and Xeon processors. Current also recently ported the technology to SuSE, where it is marketed by Novell as SUSE Linux Enterprise Real-Time (SLERT).
