    multi-processor issues

    807557
      Hello,

      Is it possible to bind one of the processors of a dual-core system exclusively to Threads and the other to RealtimeThreads? What I am trying to get here is my application to behave like it does on a uniprocessor system.(e.g. the low priority realTimeThread does not make any progress until the high priority realTimeThread finishes its job )

      Thanks

          See the sections on:

          Solaris: Using Processor Sets for Optimal Determinism
          Linux: Using Cpusets and Processor Affinity for Optimal Determinism

          in the Tech Info Guide:

          http://java.sun.com/javase/technologies/realtime/reference/doc_2.2/release/JavaRTSTechInfo.html

          But note these only affect application real-time threads. VM real-time threads, such as RTGC will execute on the non-realtime processor/set

          Hope that helps.
