12
+ * Stream pool note.
13
+ *
14
+ * A CUDAStream is an abstraction of an actual cuStream on the GPU. CUDAStreams
15
+ * are backed by cuStreams, but they use several pools to minimize the costs
16
+ * associated with creating, retaining, and destroying cuStreams.
17
+ *
18
+ * There are three pools per device, and a device's pools are lazily created.
19
+ *
20
+ * The first pool contains only the default stream. When the default stream
21
+ * is requested it's returned.
22
+ *
23
+ * The second pool is the "low priority" or "default priority" streams. In
24
+ * HIP builds there is no distinction between streams in this pool and streams
25
+ * in the third pool (below). There are 32 of these streams per device, and
26
+ * when a stream is requested one of these streams is returned round-robin.
27
+ * That is, the first stream requested is at index 0, the second at index 1...
28
+ * to index 31, then index 0 again.
29
+ *
30
+ * This means that if 33 low priority streams are requested, the first and
31
+ * last streams requested are actually the same stream (under the covers)
32
+ * and kernels enqueued on them cannot run concurrently.
33
+ *
34
+ * The third pool is the "high priority" streams. The third pool acts like
35
+ * the second pool except the streams are created with a higher priority.
36
+ *
37
+ * These pools suggest that stream users should prefer many short-lived streams,
38
+ * as the cost of acquiring and releasing streams is effectively zero. If
39
+ * many longer-lived streams are required in performance critical scenarios
40
+ * then the functionality here may need to be extended to allow, for example,
41
+ * "reserving" a subset of the pool so that other streams do not accidentally
42
+ * overlap the performance critical streams.
43
+ *
44
+ * Note: although the notion of "current stream for device" is thread local
45
+ * (every OS thread has a separate current stream, as one might expect),
46
+ * the stream pool is global across all threads; stream 0 is always stream 0
47
+ * no matter which thread you use it on. Multiple threads can synchronize
48
+ * on the same stream. Although the CUDA documentation is not very clear
49
+ * on the matter, streams are thread safe; e.g., it is safe to enqueue
50
+ * a kernel on the same stream from two different threads.

12
+ * CPUCachingAllocator:
13
+ * DISCLAIMER:
14
+ * This is subject to change (beta) and only supported on mobile builds.
15
+ * If code snippet such as in 'Usage pattern' is used outside of mobile
16
+ * build you will not observe the intended behavior.
17
+ * See below for more information.
18
+ * Why?
19
+ * It has been observed that some mobile platforms, such as pixel 3, return
20
+ * memory aggressively to the system. This results in page faults in some
21
+ * cases and ends up hurting performance. This caching allocator aims to address
22
+ * that. Furthermore it also allows users to specify their own allocator by
23
+ * implementing allocate/free virtual interfaces. What are the cons? There are
24
+ * some cons that were observed where use of caching allocator led to worse
25
+ * performance on some platforms. Reason being that the caching mechanism used
26
+ * by this allocator left us worse off compared to the corresponding platform's
27
+ * tuned memory allocator. In that case it seemed better to not use this
28
+ * allocator. Note there are some ideas to fix this in the works.
29
+ *
30
+ * Usage:
31
+ * Usage pattern:
32
+ * Instantiate and own the caching allocator.
33
+ * std::unique_ptr<c10::CPUCachingAllocator> caching_allocator =
34
+ * std::make_unique<c10::CPUCachingAllocator>();
35
+ * Use caching allocator with a scoped guard at inference time.
