Fujitsu accelerates verification of Java software through parallel processing.

PhysOrg.com (12/24/10)

 Fujitsu Laboratories has developed a way to verify Java software using parallel processing by using cloud computing services to shorten the time need for verification. The technique expands on symbolic execution, which automatically executes tests on Java programs, making it possible to process character string data. In a recent experiment using processing nodes, the technique outperformed existing technology about tenfold. The program utilizes parallelization that divides the symbolic execution processing among multiple processing nodes, which accelerates the testing. The technique also uses dynamic load balancing, which redistributes the processing of overloaded nodes to idle nodes. If a certain node takes too long to process the data, the program moves some of the data to other nodes that are finished processing, thereby achieving the faster total processing time through parallelization.
