| <p>In concurrent programming, sometimes it is desirable to make sure commonly accessed pieces of |
| data are not placed into the same cache line. Updating an atomic value invalidates the whole |
| cache line it belongs to, which makes the next access to the same cache line slower for other |
| CPU cores. Use <code>CachePadded</code> to ensure updating one piece of data doesn’t invalidate other |
| cached data.</p> |
| <h2 id="size-and-alignment"><a href="#size-and-alignment">Size and alignment</a></h2> |
| <p>Cache lines are assumed to be N bytes long, depending on the architecture:</p> |
| <ul> |
| <li>On x86-64, aarch64, and powerpc64, N = 128.</li> |
| <li>On arm, mips, mips64, and riscv64, N = 32.</li> |
| <li>On s390x, N = 256.</li> |
| <li>On all others, N = 64.</li> |
| </ul> |
| <p>Note that N is just a reasonable guess and is not guaranteed to match the actual cache line |
| length of the machine the program is running on. On modern Intel architectures, spatial |
| prefetcher is pulling pairs of 64-byte cache lines at a time, so we pessimistically assume that |
| cache lines are 128 bytes long.</p> |
| <p>The size of <code>CachePadded<T></code> is the smallest multiple of N bytes large enough to accommodate |
| a value of type <code>T</code>.</p> |
| <p>The alignment of <code>CachePadded<T></code> is the maximum of N bytes and the alignment of <code>T</code>.</p> |
| <h2 id="examples"><a href="#examples">Examples</a></h2> |
