title: Coprocessor accelerators compared to GPUs
body: <p>Are coprocessors like <em>Intel Xeon-Phi</em> supposed to be utilized much like the GPUs, so that one should offload a large amount of blocks executing <strong>a single kernel</strong>, so that only the overall throughput the coprocessor handles results in a speed up, <strong>OR</strong> offloading independent threads (tasks) will increase the efficiency as well?</p>
