OSF/1 AD For The Intel Paragon
Locus was commissioned by Intel to produce a multiprocessor version of OSF/1 for the Intel Paragon a massively parallel NORMA (No Remote Memory Access) system. The system was known as OSF/1 AD, where AD stood for "Advanced Development".
To allow inter processor process migration and communication between the individual nodes of the Paragon system they re-worked the TCF technology from LOCUS as Transparent Network Computing, or TNC, inventing the concept of the VPROC (virtual process) an analogy of the VNODE (virtual inode) from the SunOS virtual file system.
Famous quotes containing the word paragon:
“We can paint unrealistic pictures of the jugglerdisplaying her now as a problem-free paragon of glamour and now as a modern hag. Or we can see in the juggler a real person who strives to overcome the obstacles that nature and society put in her path and who does so with vigor and determination.”
—Faye J. Crosby (20th century)
