Abstract
Existing Grid workflow tools assume that individual
components either communicate by passing files from
one application to another, or are explicitly linked
using interprocess communication pipes. When files
are used it is usually difficult to overlap reader and
write execution. On the other hand, interprocess
communication primitives are invasive and require
substantial modification to existing code. We have built
a library, called GriddLeS, that combines the
advantages of both approaches without any changes to
