Hi, > The Usenix papers are generally available for anonymouse FTP, both by > the authors home site, and from the Usenix SAGE group ftp site.

Actually, I'd like to implement a sort of DSM that provides page-in/out over the network transparently to the user process. > There are a couple of Usenix papers on this technique as well; other > papers are available at the CS department of Washington State University's > FTP server. I haven't checked this yet but I'll try it. Thanks! --- Motonori Shindou
