【Abstract】 Checkpoint mechanism is studied and used widely in process migrating,load balancing and fault tolarance in parallel programs.An impletmentation of checkpoint machanism in parallel debugger which uses global breakpoint to ensure the consistence of checkpoints is presented,and the impletmentation method in PVM environment is discussed,in order to provide one method to debug PVM parallel programs quickly and conveniently.更多还原
