Multi-engine <strong>on</strong> Haswell/Broadwell<br />
<str<strong>on</strong>g>DirectX</str<strong>on</strong>g> <str<strong>on</strong>g>12</str<strong>on</strong>g> exposes multiple “queues” to applicati<strong>on</strong><br />
– <strong>Graphics</strong>/compute, compute-<strong>on</strong>ly, copy, etc.<br />
<strong>Graphics</strong> and compute are not simultaneous <strong>on</strong> <strong>Intel</strong><br />
– Using separate queues is not a performance benefit<br />
– C<strong>on</strong>sider doing both <strong>on</strong> the main queue<br />
There is a simultaneous copy engine<br />
– … but it has fairly low throughput<br />
– Driver may implement large copies using the 3D engine<br />
