I'm using both pSOS (the well-known real-time single processor kernel)
and pRISM (an extension of the pSOS interprocess communications primitives
to multi-CPU systems) from Software from Software Components Group (who
originally designed pSOS, I believe).  I was wondering if VxWorks supports
anything like the pRISM primitives.  Can you at least buy an add-on
package for VxWorks to get these primitives?
