| b7a88f0 | Andrew Adams | 01 September 2020, 18:22:25 UTC | Clean up scatter/gather hvx intrinsics I was very surprised to see scatter/gather intrinsics, because that would be a substantial IR design change - currently we don't use intrinsics for anything that mixes vector lanes (i.e. intrinsics should vectorize trivially, and we should be able to slice up wide vectors into narrow vectors trivially when using intrinsics). These are only used in the HVX backend though, so I guess within that restricted scope it's reasonable, because they're handled specially. I prefixed them with hvx_ to make this clearer and modified some code to avoid string comparisons. | 01 September 2020, 18:22:25 UTC |

| b101595 | Andrew Adams | 25 August 2020, 19:52:18 UTC | Exhaustively compute max on host for non-monotonic shared memory sizes GPU kernel launches must use the same amount of shared memory per block, and this has to be computed ahead of time on the host. The expression that gives the size of the allocations compute_at blocks are inside the kernel though, and are a function of bounds inference. We therefore have to take the max of these sizes over all blocks. This is extremely prone to interval arithmetic being overconservative, because these are extents computed from a max minus a min, and the max and min are both frequently correlated with the block variable. This causes a lot of otherwise fine schedules to fail at runtime with CUDA_ERROR_INVALID_VALUE. This PR detects cases where interval arithmetic is going to be overconservative using is_monotonic, and hoists the computation of shared memory size to an explicit loop over blocks on the CPU, taking the max shared allocation size exhaustively. This implies some work on the CPU, but 1) A loop over blocks is typically at least 32x fewer iterations than the loop over pixels 2) This work can overlap with the previous kernel launch on the GPU still running 3) The alternative is crashing This feature has proved to make GPU schedules much more robust in the gpu autoscheduler branch, so I think we should promote it to master. It's a bit wild though, because this is the first instance I can think of where we inject a new unscheduled loop for some bounds inference purpose. | 25 August 2020, 19:52:18 UTC |

| 95adfce | Andrew Adams | 24 August 2020, 01:03:08 UTC | Avoid C++ name mangling issues when calling between runtime modules Different runtime modules are initially compiled to llvm bitcode with different target triples (to support stdcall stuff on windows without requiring a precompiled windows version of every single runtime module). These triples are unified before the modules are linked, but before that happens we need to avoid anything target-triple-sensitive done by clang when compiling to llvm assembly (e.g. structs that need padding bytes). One such issue is calling c++ functions across runtime modules. The name mangling could work out differently on both sides of the call. This PR removes all instances of this (at least the ones that go via runtime_internal.h) The functions declared in Halide::Runtime::Internal didn't seem any more internal than the extern "C" functions declared immediately above it, so I promoted those functions (e.g. halide_abort()) to there. | 24 August 2020, 01:03:08 UTC |
