I'm studying the problem of attempting to off-load non-interactive processes from one machine intended to be used primarily for interactive work for many users to another machine intended to run non-interactive tasks. (Both machines are VAX/780s running 4.2bsd) I'm interested in any work that has been done in this area. In particular, I would like to find or write software to enable the transfer of files to the backend machine, execution of a command script there, and transfer of files back to the interactive machine, without it being necessary for the user to have a login on the backend machine. Less general software that performs this task for specific commands (e.g. troff) would also be helpful.

Here at Berkeley we are running some code that sends remote Pascal and C compilations to idle 750's via the ethernet. So far we have found that the five 11/750's being used a process servers have not had their performance markedly decreased, while the loads on the senders has remarkably decreased (from an average of about 9-10 to about 3-4). If you would like, mail me and I will see about getting you a copy of the research proposal and reports. David C.

We do this routinely at Maryland for troff's. When the load goes above a certain level all troff's on the high load machine are shipped for remote execution to one of several machines (depending on which is up). Generally, the users don't know the difference. Steve@Maryland, who wrote most of the code, can say more. -mark -- Spoken: Mark Weiser ARPA: mark@maryland Phone: +1-301-454-7817 CSNet: mark@umcp-cs UUCP: {seismo,allegra}!umcp-cs!mark USPS: Computer Science Dept., University of Maryland, College Park, MD 20742
