I'm not so sure about that, the first thing I came across described as a coprocessor was the "Tube" for the BBC Micro in the mid 1980's. It was a Z80 in an external expansion unit that let you run CP/M (which the hosts 6502 CPU couldn't of course). The distinction between the two has come up on the hwloc-devel mailing list where they pondering where new devices should sit in their current GPU and co-processor categories, and wondering whether to call them coprocessors or accelerators. Personally I feel that accelerator is a superset that includes co-processors. cheers, Chris - -- Christopher Samuel Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: sam...@unimelb.edu.au Phone: +61 (0)3 903 55545 http://www.vlsci.org.au/ http://twitter.com/vlsci -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlE+aosACgkQO2KABBYQAh+U6gCdE6mQwFtVK4FHICunx+4O9gSr S3YAn3tkT/74VGUpRrbn5AaaHZdbyi43 =2Noh -----END PGP SIGNATURE----- _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
