Migration Away From PSOS
In March 2000, rival company Express Logic released their Evacuation Kit for pSOS+ users, designed to provide a migration path to its ThreadX RTOS.
In August 2007, RoweBots, a former partner of SCG and ISI, open sourced their pSOS+ compatible version called Reliant. It is available to all that wish to upgrade without applications changes.
The Xenomai project supports pSOS+ APIs (and others traditional RTOS APIs) over a Linux-based real-time framework to allow existing industrial applications to migrate easily to a GNU/Linux-based environment while keeping stringent real-time guarantees.
