Another project which supports load leveling is the CoCheck project. As
the above mentioned migration environments for PVM CoCheck uses process
migration to evenly distribute the load among the workstations in the 
network. In difference to the above mentioned environments CoCheck is
complete build outside of PVM, whereas the other environments all have
modified the original PVM sources. Hence, CoCheck can easily keep up with
the latest PVM version.
In addition to process migration CoCheck also provides checkpoint/restart
facilities, which can be used as a global preemptive scheduler in
resource management systems. In the future CoCheck will be used by
CONDOR and CARMI to provide the necessary resource management for PVM
applications.
Besides, CoCheck also can be used in concert with MPI to provide process
migration and checkpointing for MPI applications.
