The kernel patch does a gross type of colored allocation by grabbing pages from the free list until it gets one of the right color - the intent is not to study the os overheads of doing colored allocations, rather the benefits a program might see from using pages allocated in such fashion. My findings are at http://reality.sgi.com/kanoj_engr/ccdis.html and it has at least one unexplained observation. If you are interested in this sort of thing, please browse it and send me comments about how I can improve the study. Pointers to apps which are suspected to benefit from cache coloring would also help. Thanks.
