<p>Technologies are generally described herein for determining a profitability of direct fetching in a multicore processor. The multicore processor may include a first and a second tile. The first tile may include a first core and a first cache. The second tile may include a second core, a second cache, and a fetch location pointer register (FLPR). The multicore processor may migrate a thread executing on the first core to the second core. The multicore processor may store a location of the first cache in the FLPR. The multicore processor may execute the thread on the second core. The multicore processor may identify a cache miss for a block in the second cache. The multicore processor may determine whether a profitability of direct fetching of the block indicates direct fetching or directory-based fetching. The multicore processor may perform direct fetching or directory-based fetching based on the determination.</p> |
