Webskew: [adjective] set, placed, or running obliquely : slanting. WebNext, the system determines a skew value for a cache line containing the object, wherein data within the cache line is shifted based upon the skew value, so that reference fields with small negative offsets are likely to be located in the same cache line as scalar fields with small positive offsets. Next, the system uses the skew value in ...
