Hello Wes Brown (wes@prozac.student.cwru.edu); quoting you from relcom.fido.ru.unix <49j9vs$4fu@madeline.INS.CWRU.Edu> :
: What do you want to do? {I am sorry VMS was before my time}
: We have LINUX running in what could be considered a cluster configuration.
: One 80386 25MHz is a dedicated machine. There are other machines that mount
: its disk space. Those machines are owned by other students that also run DOS
: and other useless excusses for operating systems.
No, "clustering' means something more than simple NFS mounting.
I mean that several machines can run (even more than) one task
in parallel, synchronizing them with some kind of Message Passing
Interface, with a shared (or divided into several chunks)
dataset.
For an example of FreeBSD solution I've recently (shame on me! :)
discover see http://www.geli.com and http://www.netlib.org/pvm3
I wonder if even more sophisticated approach is implementable:
have several motherbards (each has it's own private disk space,
too) chained with a single SCSI-2 ribbon cable,
and a shared disk space on the same cable, too; while messages
are passed via Fast Ethernet, for example, all access to a shared
data set is done via a SCSI-2 bus. That might be a very fail-safe
configuration! :-)
