GNU Compiler Collection 4.2

PARALLEL SPEED

Author(s):

The latest GNU compiler provides better support for parallel programming, and GCC also rolls out some new optimization features. We took GCC 4.2 for a test drive.

The most significant change with version 4.2 is support for OpenMP [3], an open standard for program parallelization – especially for systems with shared memory. OpenMP lets programmers specify how the compiler and run-time systems will distribute code segments over multiple threads for parallel execution on multi-core systems.
