Systems and methods provide a single reader single writer (SRSW) queue structure having entries that can be concurrently accessed in an atomic manner with a single memory access. The SRSW queues may be combined to create more complicated queues, including multiple reader single writer (MRSW), single reader multiple writer (SRMW), and multiple reader multiple writer (MRMW) queues.

High performance queue implementations in multiprocessor systems

A method comprising calculating first and second allocation speeds respectively for at least a first space and a second space in a runtime environment's memory space; and partitioning the runtime environment's memory space in proportion to said first and second space's respective allocation speeds so that the first space is filled to a first threshold level approximately at the same time as the second space is filled to a second threshold level.

Efficient heap utilization and partitioning

Techniques that may be utilized in a multiprocessor system are described. In one embodiment, one or more signals are generated to indicate that a breakpoint instruction is executed by one of the plurality of processors in the multiprocessor system. For example, a signal may be generated to indicate whether a processor is to be halted once it receives the a signal that indicates the breakpoint instruction. Other embodiments are also disclosed.

Multiprocessor breakpoint

There is provided a method and apparatus to reduce access to shared data storage. The apparatus analyzes a multithreaded application and generates metadata that is utilized to optimize the multithreaded application that executes on multiple processing elements.

Apparatus, systems and methods to reduce access to shared data storage

In one embodiment of the invention, a first reference to a first object is recorded in a first list when a first thread in a multi-thread environment invokes a lock operation on the first object. A thread-safe locking mechanism on the first object in the first list is restored when a second thread is created.
