hatholielce Universiteit Leuven Electrical Engineering Dept . - ACCA Hard . Vlercierlaan 94 - B-3001 Heverlee - Belgium Abstract We describe a distributed, multimedia application which is being developed in the framework of the ESPRIT-IV Project 21012 EFTOS (E-ncbedded FaultTolerant Superromputiny) . The application dynanr,ically sets up a hiera'r'cliy of HTML pages reflectirlq the current status of ara EFTOS-corral9hant dependable application rurtrairry on a Parsytec CC system . These pages are fed to a World-Wide 'Web br'owser' plrlyiray the role of a hypermedia ntoraitor. The adopted approach allows thr~ v.ser to corr4cerIL"atc orl th(' lciglt-level r1. .spects of his/lter apphcratiorr .so to quickly assess tlec quality of its cur-rerat fault-toleraraee design . This vievr Of the system lends itself well for lxircg cov.plcd with rl lool to interactively inject software faults 'I'll tlae user rcpplication ; this tool is currently ;,ruder development .
