Earlier versions of Vxworks didn't support multiprocessing but I read Vxworks 6.6 and above support SMP (Symmetric multiprocessing).SMP would allow process to run parallel in multiple cores. But does Vxworks support multi-programming? One of the issues with Vxworks was that since whole software is one program, if one thread crash the whole software crash! Is it still the case?
Does Vxworks support multiprogramming?

The answer is Yes. There are several specific answers of Yes. VxWorks 6.x and 7.x have process models (called RTPs) VxWorks 6.6+ and 7.x have SMP. VxWorks 7.x have memory models more like Unix.
VxWorks 6.x and VxWorks 7 both have Posix pthreads and native multiprogramming API including processor affinity API

I am using Vxworks 6.8 and it supports multiple threads well. Crash in a thread is isolated to it. Crashed thread terminates while others keep their execution.
