  • Fault tolerant patent application for virtual machine

    [0018]For incoming network packets, the following is done during the logging mode. When a packet is received, an event-request is posted for the VMM, at Block 210.

And why were only 20 percent of computer science undergraduates at M.I.T. female? She published a 124-page paper, “”Why Are There So Few Female Computer Scientists?”, that catalogued different…

  • Supercomputing and mathematica

    The last time I went to a “Supercomputing” conference, Jim Gray came by to talk to me and Cort about PowerPC Linux. That must have been in 2000 or 1999.
