However, when we write many small blocks, this compressed block size estimate is much larger than what is needed, leading to high memory use for wide/short tables. This PR adds logic to take the actual block size into account, and to use the size of the actual largest block in the file, not the largest possible block. This changes the memory usage by orders of magnitude in some tests. --------- Co-authored-by: Bradley Dice --- cpp/src/io/orc/writer_impl.cu | 20 +++++++++++++++++++- cpp/src/utilities/host_memory.cpp | 1 + cpp/tests/CMakeLists.txt | 4 ++-- 3 files changed, 22 insertions(+), 3 deletions(-) diff --git a/cpp/src/io/orc/writer_impl.cu b/cpp/src/io/orc/writer_impl.cu index 3a20ffbce19..217aff48d5e 100644 --- a/cpp/src/io/orc/writer_impl.cu +++ b/cpp/src/io/orc/writer_impl.cu @@ -2226,6 +2226,22 @@ stripe_dictionaries build_dictionaries(orc_table_view& orc_table, std::move(dict_order_owner)}; } +[[nodiscard]] uint32_t find_largest_stream_size(device_2dspan ss, + rmm::cuda_stream_view stream) +{ + auto const longest_stream = thrust::max_element( + rmm::exec_policy(stream), + ss.data(), + ss.data() + ss.count(), + cuda::proclaim_return_type([] __device__(auto const& lhs, auto const& rhs) { + return lhs.stream_size < rhs.stream_size; + })); + + auto const h_longest_stream = cudf::detail::make_host_vector_sync( + device_span{longest_stream, 1}, stream); + return h_longest_stream[0].stream_size; +} + /** * @brief Perform the processing steps needed to convert the input table into the output ORC data * for writing, such as compression and ORC encoding. @@ -2319,7 +2335,9 @@ auto convert_table_to_orc_data(table_view const& input, size_t compressed_bfr_size = 0; size_t num_compressed_blocks = 0; - auto const max_compressed_block_size = max_compressed_size(compression, compression_blocksize); + auto const largest_stream_size = find_largest_stream_size(strm_descs, stream); + auto const max_compressed_block_size = + max_compressed_size(compression, std::min(largest_stream_size, compression_blocksize)); auto const padded_max_compressed_block_size = util::round_up_unsafe(max_compressed_block_size, block_align); auto const padded_block_header_size = diff --git a/cpp/src/utilities/host_memory.cpp b/cpp/src/utilities/host_memory.cpp index 94d27d976c3..e41d772a479 100644 --- a/cpp/src/utilities/host_memory.cpp +++ b/cpp/src/utilities/host_memory.cpp @@ -29,6 +29,7 @@ namespace cudf { namespace { + class fixed_pinned_pool_memory_resource { using upstream_mr = rmm::mr::pinned_host_memory_resource; using host_pooled_mr = rmm::mr::pool_memory_resource; diff --git a/cpp/tests/CMakeLists.txt b/cpp/tests/CMakeLists.txt index cfc6a0dc425..e3ca8b70b87 100644 --- a/cpp/tests/CMakeLists.txt +++ b/cpp/tests/CMakeLists.txt @@ -309,7 +309,7 @@ ConfigureTest( ConfigureTest( ORC_TEST io/orc_chunked_reader_test.cu io/orc_test.cpp GPUS 1 - PERCENT 30 + PERCENT 100 ) ConfigureTest( PARQUET_TEST @@ -340,7 +340,7 @@ ConfigureTest(JSON_TREE_CSR io/json/json_tree_csr.cu) ConfigureTest( DATA_CHUNK_SOURCE_TEST io/text/data_chunk_source_test.cpp GPUS 1 - PERCENT 30 + PERCENT 100 ) target_link_libraries(DATA_CHUNK_SOURCE_TEST PRIVATE ZLIB::ZLIB) ConfigureTest(LOGICAL_STACK_TEST io/fst/logical_stack_test.cu) From 34235f4ebacd5982aad4c42d6886706761ac862c Mon Sep 17 00:00:00 2001 From: Matthew Murray <41342305+Matt711@users.noreply.github.com> Date: Mon, 3 Mar 2025 17:06:30 -0500 Subject: [PATCH 4/6] Use protocol for dlpack instead of deprecated function in cupy notebook (#18147) Follow up to #18134 --- docs/cudf/source/user_guide/cupy-interop.ipynb | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/docs/cudf/source/user_guide/cupy-interop.ipynb b/docs/cudf/source/user_guide/cupy-interop.ipynb index 112f0bcfca6..93e62d90c0f 100644 --- a/docs/cudf/source/user_guide/cupy-interop.ipynb +++ b/docs/cudf/source/user_guide/cupy-interop.ipynb @@ -566,7 +566,7 @@ "%%timeit\n", "\n", "fortran_arr = cp.asfortranarray(reshaped_arr)\n", - "reshaped_df = cudf.from_dlpack(fortran_arr.toDlpack())" + "reshaped_df = cudf.from_dlpack(fortran_arr.__dlpack__())" ] }, { @@ -1418,7 +1418,7 @@ "name": "python", "nbconvert_exporter": "python", "pygments_lexer": "ipython3", - "version": "3.10.12" + "version": "3.12.9" } }, "nbformat": 4, From b6a6d390f92080481606e91f40450cc4e140fa97 Mon Sep 17 00:00:00 2001 From: Vyas Ramasubramani Date: Mon, 3 Mar 2025 14:22:56 -0800 Subject: [PATCH 5/6] Skip failing test (#18146) This test is failing in multiple places right now, such as [this run](https://github.com/rapidsai/cudf/actions/runs/13595690128/job/38014725800) on https://github.com/rapidsai/cudf/pull/18133 and [this run](https://github.com/rapidsai/cudf/actions/runs/13636334843/job/38118996773?pr=18136) on https://github.com/rapidsai/cudf/pull/18136.
