| <div class="paragraph"> |
| <p>The goal of this extension is to allow programmers to improve the performance of applications operating on 64-bit data types by extending the subgroup functions described in the <code>cl_intel_subgroups</code> extension to support 64-bit integer data types (<code>longs</code> and <code>ulongs</code>). |
| Specifically, the extension:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Extends the Intel subgroup block read and write functions to allow reading and writing 64-bit integer data from images and buffers.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>Note that <code>cl_intel_subgroups</code> and <code>cl_khr_subgroups</code> already support broadcasts, scans, and reductions for 64-bit integer types, and that <code>cl_intel_subgroups</code> already supports shuffles for 64-bit integer types.</p> |
