  2. Java performance - Wikipedia

    en.wikipedia.org/wiki/Java_performance

    Thus, any Java performance test or comparison has to always report the version, vendor, OS and hardware architecture of the used JVM. In a similar manner, the performance of the equivalent natively compiled program will depend on the quality of its generated machine code, so the test or comparison also has to report the name, version and vendor ...

  4. Java memory model - Wikipedia

    en.wikipedia.org/wiki/Java_memory_model

    For the execution of a single thread, the rules are simple. The Java Language Specification requires a Java virtual machine to observe within-thread as-if-serial semantics. The runtime (which, in this case, usually refers to the dynamic compiler, the processor and the memory subsystem) is free to introduce any useful execution optimizations as ...

  5. Java concurrency - Wikipedia

    en.wikipedia.org/wiki/Java_concurrency

    Each thread can be scheduled [5] on a different CPU core [6] or use time-slicing on a single hardware processor, or time-slicing on many hardware processors. There is no general solution to how Java threads are mapped to native OS threads. Every JVM implementation can do this differently. Each thread is associated with an instance of the class ...

  6. Compare-and-swap - Wikipedia

    en.wikipedia.org/wiki/Compare-and-swap

    In computer science, compare-and-swap (CAS) is an atomic instruction used in multithreading to achieve synchronization.It compares the contents of a memory location with a given value and, only if they are the same, modifies the contents of that memory location to a new given value.

    Cycle i: instructions j and j + 1 from thread A and instruction k from thread B are simultaneously issued. Cycle i + 1: instruction j + 2 from thread A, instruction k + 1 from thread B, and instruction m from thread C are all simultaneously issued. Cycle i + 2: instruction j + 3 from thread A and instructions m + 1 and m + 2 from thread C are ...
