There was a problem hiding this comment. Ultimately, I would like to use the same default seed for all cuco benchmarks and add an option to adjust it via nvbench. We currently use |
||||||
| gen.generate(distribution::unique{}, items.begin(), items.end()); | ||||||
|
|
||||||
| thrust::device_vector<bool> contained(items.size(), false); | ||||||
|
|
||||||
| state.add_element_count(items.size()); | ||||||
| state.add_global_memory_reads<T>(items.size(), "InputSize"); | ||||||
|
|
||||||
| auto& summ = state.add_summary("BitmapSizeMB"); | ||||||
| summ.set_string("hint", "BitmapSize"); | ||||||
| summ.set_string("short_name", "BitmapSizeMB"); | ||||||
| summ.set_string("description", "Bitmap size in MB"); | ||||||
| summ.set_float64("value", static_cast<double>(file_size) / (1024 * 1024)); | ||||||
|
|
||||||
| state.exec([&](nvbench::launch& launch) { | ||||||
| roaring_bitmap.contains_async( | ||||||
| items.begin(), items.end(), contained.begin(), {launch.get_stream()}); | ||||||
| }); | ||||||
| } | ||||||
|
|
||||||
| NVBENCH_BENCH_TYPES(roaring_bitmap_contains, | ||||||
| NVBENCH_TYPE_AXES(nvbench::type_list<nvbench::uint32_t>)) | ||||||
| .set_name("roaring_bitmap_contains") | ||||||
| .add_int64_power_of_two_axis("NumInputs", {32}) | ||||||
| // Default benchmark is only available if the Roaring bitmap testdata has been downloaded | ||||||
| #ifdef CUCO_ROARING_DATA_DIR | ||||||
| .add_string_axis("BitmapFile", {std::string(CUCO_ROARING_DATA_DIR) + "/bitmapwithruns.bin"}) | ||||||
