Abstract
We have constructed a distributed computing platform with eight proces sors to assemble and filter data from digitization crates. The filtere d data were transported to a tape-writing UNIX computer via ethernet. Each processor ran a UNIX operating system and was installed in its ow n VME crate. Each VME crate contained dual-port memories which interfa ced with the digitizers. Using standard hardware and software (VME and UNIX) allows us to select from a wide variety of non-proprietary prod ucts and makes upgrades simpler, if they are necessary.
