DESCRIPTION
Because of cpu aliasing problems, there are a lot of problems with stalled pipelines. A famous problem is at: http://stackoverflow.com/questions/8547778/why-is-one-loop-so-much-slower-than-two-loops

This library tries to intercept the memory allocations to skew the allocations to different offsets, so the performance penalty to disappear.

Applications that process a lot of data in big memory allocations will benefit from this application without recompiling the sources (if available).

HOW IT WORKS
cpublaster is a shared object that hooks memory allocation functions and add an small offset to them.

Fine tuning can be done using environment variables described below.

EXAMPLES
0. Output debug stuff in a log file (for debugging):

export CPUBLASTER_VERBOSE=999

export CPUBLASTER_LOG="xxx.log"

1. verbose operations:

export CPUBLASTER_VERBOSE=999

export CPUBLASTER_LOG="xxx.log"

export CPUBLASTER_MINIM_ALLOCATION=128

export CPUBLASTER_INCREMENT=128
