From 2c363b5f0b4595f91c29ca7eaaf2d46a2f3514bf Mon Sep 17 00:00:00 2001 From: George Hotz <72895+geohot@users.noreply.github.com> Date: Thu, 30 Nov 2023 17:07:16 -0800 Subject: [PATCH] new style device (#2530) * cpu tests pass * torch works * works * metal works * fix ops_disk * metal jit works * fix openpilot * llvm and clang work * fix webgpu * docs are rly broken * LRU works on metal * delete comment * revert name to ._buf. LRU only on Compiled * changes * allocator * allocator, getting closer * lru alloc * LRUAllocator * all pass * metal * cuda * test examples * linearizer * test fixes * fix custom + clean realize * fix hip * skip tests * fix tests * fix size=0 * fix MOCKHIP * fix thneed * copy better * simple * old style metal copy * fix thneed * np reshape * give cuda a device --- .github/workflows/test.yml | 10 +- .gitignore | 2 + docs/abstractions.py | 64 +++--- examples/hlb_cifar10.py | 2 +- extra/export_model.py | 4 +- extra/hip_wrapper.py | 4 +- extra/thneed.py | 42 ++-- openpilot/compile2.py | 5 +- .../external_test_allocator_on_models.py | 125 ------------ test/external/external_test_speed_llama.py | 18 +- test/helpers.py | 2 +- test/test_allocators.py | 188 ------------------ test/test_custom_function.py | 10 +- test/test_lazybuffer.py | 1 + test/test_linearizer.py | 8 +- test/test_search.py | 4 +- test/test_uops.py | 16 +- test/unit/test_disk_tensor.py | 8 +- tinygrad/device.py | 111 ++++++++--- tinygrad/features/search.py | 21 +- tinygrad/helpers.py | 19 +- tinygrad/jit.py | 29 ++- tinygrad/lazy.py | 12 +- tinygrad/ops.py | 2 +- tinygrad/realize.py | 69 +++---- tinygrad/runtime/graph/metal.py | 78 ++++++++ tinygrad/runtime/lib.py | 105 ---------- tinygrad/runtime/ops_clang.py | 9 +- tinygrad/runtime/ops_cpu.py | 19 +- tinygrad/runtime/ops_cuda.py | 48 ++--- tinygrad/runtime/ops_disk.py | 80 ++++---- tinygrad/runtime/ops_gpu.py | 123 +++++------- tinygrad/runtime/ops_hip.py | 144 ++++---------- tinygrad/runtime/ops_llvm.py | 11 +- tinygrad/runtime/ops_metal.py | 162 ++++----------- tinygrad/runtime/ops_torch.py | 23 +-- tinygrad/runtime/ops_webgpu.py | 29 ++- tinygrad/tensor.py | 4 +- 38 files changed, 572 insertions(+), 1039 deletions(-) delete mode 100644 test/external/external_test_allocator_on_models.py delete mode 100644 test/test_allocators.py create mode 100644 tinygrad/runtime/graph/metal.py delete mode 100644 tinygrad/runtime/lib.py diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index cd88652873..2a6b7d1c02 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -197,11 +197,11 @@ jobs: -
