"OpenVMS VAX supports neither kernel threads nor upcalls."  In short, a 
pthreads application operates on a single processor on VAX.
For parallel execution across multiple processors using pthreads, Alpha 
or Itanium, and a not-antique OpenVMS version, are required.
With older OpenVMS releases, pthreads can also be sensitive to the 
particular patches, which means using a V8-vintage release is usually 
preferable.
If pthreads and/or portability is not a specific requirement for the 
work, KP Threads can sometimes be easier to deal with.
