Examples of groovyx.gpars.scheduler.DefaultPool

groovyx.gpars.scheduler.DefaultPool
Represents the actors' thread pool, which performs tasks on behalf of the actors. The actors' thread pool size defaults to the n + 1, where n is the number of processors/cores available on the machine. The VM parameter -Dgpars.poolsize can be used the configure the default size of the actors' thread pool. The resize() and resetDefaultSize() methods can be used to configure size of the thread pool at runtime. @author Vaclav PechDate: Feb 27, 2009
