XFOR

A Programming Structure to Ease the Formulation of Efficient Loop Optimizations & A Polyhedral Language
 
 

XFOR is a programming loop control structure of C/C++, allowing to outperform traditional for-loops, even when they are optimized by the best compilers. A xfor-loop defines simultaneously several loops whose bodies run in interleaved mode. Respective iteration domains are mapped onto each other according to a running frequency, the grain, and a relative position, the offset. There are 3 software tools related to XFOR:
