Original Abstract Submitted
Systems and techniques for selectively transferring one or more portions of a cache block in response to a request are described. Computing system components are informed as to instances where data transfer operations involve moving less than an entirety of data included in a cache block cache block. In one example, executable code for a computational task includes hints that identify when memory requests involve accessing and transmitting less than an entirety of a cache block and cause system components to communicate a subset of the cache block during a memory access. In another example, a data differentiator unit is implemented to analyze a cache block and return a portion of the cache block that is selected based on one or more criteria specified for a computational task. The described techniques thus overcome conventional drawbacks facing systems that transmit an entire cache block when only a portion is needed.
