cache programming

The type of applications that I am writing, use enormous amounts of RAM space, for storing processed data as cached data, so as to be used by various other applications. During this time is when I remembered about the cache (L1 and L2) used by the system processor. Though both are entirely different, it is the same as seen by a user. It is memory!!!

It is known that L1 and L2 cache are faster than the RAM, which is in turn faster than disk I/O. It is also know that L1, L2 caches are expensive than RAM.

This is when I came up with the problem of what If I wanted to make an implicit write to L1/L2 cache instead of the RAM, from a user space application.

I came up with quite a few interesting reads, and a patent for it. Check them out:

• Pentium 4 L2 cache optimization for cached writes
• Computer system cache performance...
