Taking into account parity their fault set of coarse-grained parallelism with the use of computer-based distributed parallel computing cluster, can greatly enhance the take up most of the time constraints of parity calculation speed.

Failure to take into account the checksum itself is of a coarse granularity parallelism used, based on cluster computers distributed parallel computing, can significantly enhance occupied most of the time bound the checksum calculation speed.

Considered the breakdown collection verifies the coarse grain parallelism which itself has, uses based on the colony computer distributional parallel computation, can promote to take the major part time large scale the restraint verification computation speed.

Taking into account the failure set validate itself has a coarse-grain parallelism, the use of distributed parallel computing based on cluster computer, can significantly improve take up most of the time constraint checking calculations.

Taking into account parity their fault set of coarse-grained parallelism with the use of computer-based distributed parallel computing cluster, can greatly enhance the take up most of the time constraints of parity calculation speed.
