1. Purpose of the thorn

Shared Memory Data Server. 
Interoperates with Visapult Parallel Image-Based volume renderer.
Shmem data server creates shared memory segment in which to 
store current contents of a gridfunction.  The shared memory
is then read by a "dataserver" process which is either forked
by this thorn or can be an entirely separate parallel application
that binds to the advertised shmem addresses created by 
this thorn.  This allows the data server to push packets out to
the network entirely independently of the physics part of the app
but uses fork() rather than threads() (gets around some really nasty
issues with threading).  

2. Dependencies of the thorn

This thorn additionally requires thorn PUGH.

3. Thorn distribution

This thorn is available to public.
