Uhm, that shows that you don't have _any_ idea what's going on in the automation field. IBM is an IT company, and Intel is a processor manufacturer. We are talking about the world of signal processors and PLCs here, where companies like Siemens, ABB, Schneider etc. are the big players. > My limited observations suggest that the primary reasons people do not > use Linux for their RT applications are: > > 1) They don't trust it for 'high availability'.

You would be wondering how fast you can port an application for another RTOS to RTAI. There is even a module for RTAI/LXRT which lets you run Matlab/RTW code natively on RTAI...
