Experimental Validation of

This paper presents the experkntal validation of the distributed execution of recovery blocks, in short distributed recovery block (IRB). The experiment ws conducted on a tightly coupled network (m and a time-critical application ws used as a testbed for the experiment. The concept of the IRE3 is the canbination of distributed processing and RB (Recovery Block). It is also an approach for unified treatmnt of both hardware and softwre faults. The primary objective of this experiment was to damnstrate the efficiency of the IRB scha in a tightly coupled real-tirne distributed canputing envirorment. This experirnent required tnrploying the IRE3 schm in an application program and masuring its inpact on the systan perfomnce. The min interest in measurmnts is to find the tim overhead of the IRE3 scha, i.e., the overhead of the error detection and recovery activity.
