JVM Strategie: HotSpot und JRockit Konvergenz JRockit und HotSpot werden in einem mehrjährigen Prozess zu einer einheitlichen JVM verschmolzen: HotRockit unter Berücksichtigung der besten Funktionsmerkmale beider JVM s Die Arbeitsergebnisse wurden inkrementell zum OpenJDK zugeführt JRockit Performance Funktionalität - Bereits im JDK 7 Ziele Maximale Performance und Skalierbarkeit Multi-Core und Parallelisierungs Optimierungen Feingranulares Monitoring, Profiling und Management Extrem effiziente Garbage Collection 8 Copyright 2012, Oracle and/or it s affiliates.

HotRockit Converged JVM (1) JCMD Command Line utility to enumerate and send commands to running JVMs - JDK 7 Time Frame JMX Agent Update - JDK 7 Time Frame Java Discovery Protocol JDP - JDK 7 Update Time Frame Multicasting heartbeat for JVM services Used to discover manageable JVMs on the network Also to discover JVM s no longer running Normally used with the JMX management agent MBean Updates - JDK 7 Time Frame Many MBeans from JRockit s JMXMAPI Ported Means better support for Hotspot in the Mission Control Console Examples: getjvmgeneratedcpuload(); getallocatedbytes(long[] threadids) getinvocationcount(methodid id); DiagnosticCommandMBean; gettiming(methodid id) PerfCounterMBean 9 Copyright 2012, Oracle and/or it s affiliates.

Concurrency APIs JSR166y Update to JSR166x which was an update to JSR166 Adds a lightweight task framework Also referred to as Fork/Join Phaser Barrier similar to CyclicBarrier and CountDownLatch TransferQueue interface Extension to BlockingQueue Implemented by LinkedTransferQueue 22 Copyright 2012, Oracle and/or it s affiliates. All rights reserved.
Fork Join Framework Goal is to take advantage of multiple processor Designed for task that can be broken down into smaller pieces Eg. Fibonacci number fib(10) = fib(9) + fib(8) Typical algorithm that uses fork join join fork if I can manage the task perform the task else fork task into x number of smaller/similar task join the results 23 Copyright 2012, Oracle and/or it s affiliates.

Key Classes ForkJoinPool Executor service for running ForkJoinTask ForkJoinTask The base class for forkjoin task RecursiveAction A subclass of ForkJoinTask A recursive resultless task Implements compute() abstract method to perform calculation RecursiveTask Similar to RecursiveAction but returns a result 24 Copyright 2012, Oracle and/or it s affiliates. All rights reserved.
ForkJoin Performance Discussion Choosing the sequential threshold Smaller tasks increase parallelism Larger tasks reduce coordination overhead Ultimately you must profile your code Minimizes overhead for compute-intensive tasks Not recommended for tasks that mix CPU and I/O activity A portable way to express many parallel algorithms Reasonably efficient for a wide range of core counts Library-managed parallelism 25 Copyright 2012, Oracle and/or it s affiliates.
