From a0d478adc302158c4148bbda3061d68602d47fdd Mon Sep 17 00:00:00 2001 From: Oliver Thomson Brown Date: Wed, 3 Jun 2026 11:23:47 +0100 Subject: [PATCH 1/7] Create v4.3 release candidate (#776) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Fix applyMultiStateControlledSqrtSwap argument list (#738) Remove numControls argument from applyMultiStateControlledSqrtSwap overloaded definition taking std::vector (cherry picked from commit 9c20792dce9e6a432c50b081028c717af1ff9f3d) Co-authored-by: D-Exposito * Trotterisation test update (#728) * tests/unit/trotterisation.cpp: updated to use REQUIRE_AGREE and cached statevecs and densmats, and both permutePaulis options * tests/utils/compare.hpp/cpp: added setters for test epsilon * tests/unit/trotterisation.cpp: adjusted test epsilon for quad precision imaginary time evolution tests * tests/unit/trotterisation.cpp: moved unitary time evo test to REQUIRE_AGREE * tests/utils/cache.hpp/cpp: added additional utilities for creating and destroying temp caches (which I guess makes them not caches?) with a set number of qubits * tests/unit/trotterisation.cpp: updated unitary time evo test to test across deployments * tests/unit/trotterisation.cpp: reduced number of qubits and increased number of steps to admit the possibility of testing density matrices too * tests/unit/trotterisation.cpp: added density matrix tests * reduce test precision to lazily pass CPU clang quad-precision * skip Trotter tests in paid CI * changing varname convention * renaming cache funcs --------- Co-authored-by: Oliver Thomson Brown <8394906+otbrown@users.noreply.github.com> Co-authored-by: Tyson Jones * added Daniel Patino to authorlist * CMake warn when non-release build (#742) --------- Co-authored-by: Oliver Thomson Brown * Stop Trotter funcs mutating PauliStrSum (#740) Formerly, the Trotter functions (such as applyTrotterizedPauliStrSumGadget()), when passed permutePaulis=true, would randomly permutate the order of the passed PauliStrSum, mutating it and affecting the outputs of subsequent functions like reportPauliStrSum(). The function also contained superfluous memory allocs/copies equal in size to the PauliStrSum. Now, the PauliStrSum is never mutated, and an internally allocated ordering list keeps track of the randomised permutation. We also updated the doc, renamed permutePaulis to permuteTerms, and improved validation. Note that 'permuteTerms' had not yet reached main/release, so these changes do not need to be documented in the v4.3 release notes. * Created custom backend complex types (#729) Created cpu_qcomp and gpu_qcomp (from a shared base_qcomp) to avoid std::complex arithmetic operators in hot loops which caused performance issues. Removed all prior compiler flags and related scaffolding attempting to mitigate the performance issue. Also gave MSVC build the params `/Zc:preprocessor -Xcompiler=/Zc:preprocessor /bigobj` as needed for compilation of the unit tests on my windows machines. * Replace vector with SmallList (a stack array) (#743) This is to circumvent the std::vector performance overheads visible in few-qubit simulation (responsible for a performance regression from v3; see #720), and also so that qubit lists can be passed directly to CUDA kernels without conversion (as explored in #739). * Added few-qubit optimisations (#750) Optimisations include: - Adopted SmallView (const SmallList&) to avoid superfluous SmallList copies - Made internally created matrices static - Change accelerator dynamic function vectors to static arrays - Exit all validators early when validation is disabled Additional cleanup includes: - Tidied accelerator macros (replaced param-specific macros like "numCtrls" and "numTargs" with "param") - Fill ctrlStates vectors with default before localiser - Renamed getBitsFromInteger to setToBitsOfInteger - Adopted const in bitwise.hpp to better express intent Note that the naming of SmallList and SmallView will be subsequently changed to List64 and ConstList64 * Renamed debug API functions to contain "QuEST" (#752) * Renamed environment variables to begin with"QUEST" (#755) * Renamed CMake vars and preprocessors (#756) such that they all begin with QUEST, but some have additional changes * Renamed Small(List|View) to (Const)List64 (#757) * Defer Catch2 test discovery so that we can compile MPI tests on systems which cannot actually run with MPI, because they are missing an MPI or UCX library file, as is witnessed in the CI (when compiling with MPICH). It's generally irksome too to trigger an execution of the test binary (which itself initialises QuEST) during build when on a HPC platform with distinct submit and compute nodes * Enable user to take ownership of MPI (#722) * Added ENABLE_SUBCOMM build option * Moved from MPI_COMM_WORLD to mpiQuestComm * Decided passing *MPI_Comm was probably overly cautious, and updated function name to comm_getMpiComm * environment.cpp: added methods to reset rank and numNodes, and reporting for subcomm compiled * comm_config.hpp/cpp: added comm_setMpiComm * CMakeLists.txt: PUBLIC MPI::MPI_CXX turned out to be unhelpful, even for SubComm, because of course it enforces CXX * Added new custom QuESTEnv initialiser which allow user to positively declare that they take ownership of MPI * validation.cpp: updated comm_end call * comm_config.hpp: added config.h include so COMPILE_MPI is actually defined * subcommunicator.h/cpp: implemented QuESTEnv initialiser with custom MPI_Comm * CMake: added subcommunicator.cpp * comm_config.hpp: added missing config.h include... * comm_config.cpp: explicitly initialise mpiCommQuest to MPI_COMM_NULL, updated setComm for init only workflow * quest.h: added subcommunicator header * CMake: added MPI to application binaries when SUBCOMM is enabled * comm_routines.cpp: post Irecv before Isend which probably won't do anything but it makes MPI library implementers less nervous * tests: added new env test for initCustomMpiQuESTEnv * Added error throws to comm_config to cover new scenarios of badness with user owned MPI * subcommunicator.cpp: updated var names to match QuEST style * tests/unit/initialisations.cpp: slightly modified setQuregAmps test to avoid unexpected test failure due to range checking when compild in Debug configuration * Updated validation in comm_setMpiComm Co-authored-by: iarejula-bsc * userOwnsMpi int->bool * comm_config.cpp: corrected call to MPI_Comm_free * subcommunicator.cpp: userOwnsMpi int->bool * subcommunicator.cpp: added comm_isInit guard around comm_setMpiComm * environment.cpp: USER_OWNS_MPI -> userOwnsMpi * comm_init: fixed case where useDistrib = 0 and userOwnsMpi = true * comm_init: moved (recently) misplaced MPI_Init * AUTHORS.txt: added iarejula-bsc * Added placeholder docstrings to new initialisers * docs/cmake.md: added ENABLE_SUBCOMM to list of QuEST CMake vars * Newly added COMPILE_MPI -> QUEST_COMPILE_MPI * ENABLE_SUBCOMM -> QUEST_ENABLE_SUBCOMM * CMake: corrected OpenMP and subcommunicator pre-processor definitions --------- Co-authored-by: Oliver Thomson Brown <8394906+otbrown@users.noreply.github.com> Co-authored-by: iarejula-bsc * Add flush and sync around prints (#763) to reduce the likelihood of users printing from non-root nodes interrupting QuEST root output. This is not bullet-proof; we sync the active communicator rather than MPI_COMM_WORLD so the user-controlled non-participating processes may still be printing. Furthermore, even if all processes participate, some may have outstanding non-root prints that are not aggregated to the user screen by the time MPI_Barrier finishes. But these syncs greatly reduce the change of corruption, and are effectively free! * Add GPU-aware MPICH detection This enables CRAY MPICH platforms to leverage GPU-awareness, greatly accelerating distributed GPU simulation Co-authored-by: JPRichings * Cleanup custom MPI flow (#762) Important changes: - permit user initialisation of MPI when QuEST is not distributed - changed QuESTEnv fields bool from int (e.g. isMultithreaded) - add user-input validation for custom MPI calls - disambiguated comm_config.cpp concepts of "MPI is initialised" (comm_isMpiInit) from "QuEST communication is active" (comm_isActive) - refactored comm_config.cpp flow, especially related to pre-quest-init flow (during validation) - added Oliver's custom-MPI examples (from #712) - moved new API functions to experimental.h - tweaked reportQuESTEnv output grouping * Added user-control of GPU num threads per block (#736) Added: - QUEST_DEFAULT_NUM_GPU_THREADS_PER_BLOCK CMake option - QUEST_DEFAULT_NUM_GPU_THREADS_PER_BLOCK environment variable - setQuESTNumGpuThreadsPerBlock() API function - getQuESTNumGpuThreadsPerBlock() API function - set_num_gpu_threads examples in examples/extended --------- Co-authored-by: Oliver Thomson Brown <8394906+otbrown@users.noreply.github.com> Co-authored-by: Tyson Jones * Fix compiler warnings (#770) Beware this included removing the superfluous `numControls` argument from the C++only `std::vector` overload of `applyMultiStateControlledCompMatr2`, which is technically a teeny tiny API break ¯\_(ツ)_/¯ * tests/unit/debug.cpp: updated setQuESTSeeds validation tests to include new validation (#771) Updated number of seeds test to use a valid pointer and added a separate NULL pointer test. * Fix Windows CI test_free.yml: added Release config to ctest commands (#773) --------- Co-authored-by: D-Exposito Co-authored-by: Oliver Thomson Brown <8394906+otbrown@users.noreply.github.com> Co-authored-by: Tyson Jones

The exported target requests C11 for C consumers and C++14 for C++ consumers. QuEST's C++17 implementation and GPU C++20 requirements remain private build requirements. Installed GPU packages can be consumed without enabling CUDA or HIP as project languages. + +Configure the consumer with the QuEST prefix when it is outside CMake's normal search locations: + +```bash +cmake -S consumer -B consumer-build -DCMAKE_PREFIX_PATH=/opt/QuEST +cmake --build consumer-build +``` + +The installed configuration rediscovers the dependencies required by the built library before loading `QuEST::QuEST`. It does not consult downstream `QUEST_*` settings or `BUILD_SHARED_LIBS` to reinterpret the installed binary. Static packages can therefore require development packages for enabled OpenMP, NUMA, MPI, CUDA, HIP, cuQuantum, or ADIOS2 backends. MPI is also a public requirement when QuEST was built with the subcommunicator API because its public header exposes `mpi.h`. Shared packages preserve their external runtime requirements while avoiding private SDK development requirements where the link interface does not need them. + +ADIOS2 builds select the serial or MPI C++ target to match QuEST's MPI configuration. Current ADIOS2 packages normally provide `adios2::cxx` and `adios2::cxx_mpi`; ADIOS2 2.9 packages, including Ubuntu 24.04, use the compatible legacy names `adios2::cxx11` and `adios2::cxx11_mpi`. QuEST records the selected target and requires the same interface when a static installation is consumed. + +QuEST installs its reusable cuQuantum and cuTENSOR find modules with the package. When a static built library uses cuQuantum, `QuESTConfig.cmake` makes this dependency request before loading the exported target: + +```cmake +find_package(CUQUANTUM MODULE REQUIRED COMPONENTS cuStateVec) +``` + +Consumers still call only `find_package(QuEST CONFIG REQUIRED)`. The static package records the producer's cuStateVec component version and requires an equal or newer version with the same major ABI. A shared QuEST package retains its cuQuantum runtime requirement without resolving private SDK development files during consumer configuration. + +The available cuQuantum imported targets are `CUQUANTUM::cuStateVec`, `CUQUANTUM::cuTensorNet`, and `CUQUANTUM::cuDensityMat`. Calling the finder without components requests all three. Each component's header and shared library are resolved independently; the finder does not substitute the SDK's `_static` archives. Set `CUQUANTUM_ROOT` or its environment variable to the SDK prefix and `CUDAToolkit_ROOT` to CUDA. cuTensorNet and cuDensityMat also require cuTENSOR and accept `CUTENSOR_ROOT`. An explicitly set `CUQUANTUM_DIR` remains a legacy prefix hint with precedence over these general roots. Component versions are reported separately as `CUQUANTUM__VERSION`; they are not the overall SDK release version. + + +--------------------------- + +## Creating packages + +For a standalone installable build, CPack is enabled by default after the installation rules.

Packages contain only QuEST-owned files and combine the QuEST components into one complete archive. The install components are `Runtime`, `Development`, and, when installable examples were built, `Examples`. `Development` contains headers, CMake exports and find modules, static or import libraries, and linker namelinks. A shared `Development` package depends on the exact `Runtime` version; a static build has no empty runtime dependency. + +Native package profiles are available with `-DQUEST_NATIVE_PACKAGE_PROFILE=ubuntu24.04` for DEB and `-DQUEST_NATIVE_PACKAGE_PROFILE=fedora44` for RPM. Supported hosts are detected when the variable is empty; use `custom` for an explicitly described vendor environment. Native profiles install under `/usr` and use GNU installation directories. They produce `libquest4`, `libquest-dev`, and optional `quest-examples` packages on Debian, or `quest`, `quest-devel`, and optional `quest-examples` packages on Fedora. + +Fedora's stock Open MPI installation is module-based.

The static pack The available cuQuantum imported targets are `CUQUANTUM::cuStateVec`, `CUQUANTUM::cuTensorNet`, and `CUQUANTUM::cuDensityMat`. Calling the finder without components requests all three. Each component's header and shared library are resolved independently; the finder does not substitute the SDK's `_static` archives. Set `CUQUANTUM_ROOT` or its environment variable to the SDK prefix and `CUDAToolkit_ROOT` to CUDA. cuTensorNet and cuDensityMat also require cuTENSOR and accept `CUTENSOR_ROOT`. An explicitly set `CUQUANTUM_DIR` remains a legacy prefix hint with precedence over these general roots. Component versions are reported separately as `CUQUANTUM__VERSION`; they are not the overall SDK release version. +On Linux and macOS, installed QuEST targets use a relative runtime search path (`$ORIGIN` or `@loader_path`) to locate the QuEST library within the install prefix. Explicit `CMAKE_INSTALL_RPATH` entries are preserved. QuEST supplies defaults for the target properties `BUILD_RPATH_USE_ORIGIN` and `INSTALL_REMOVE_ENVIRONMENT_RPATH` only when those properties have not already been set, including through their corresponding `CMAKE_*` variables. An explicit `OFF` remains in effect.

It does not bundle CUDA, cuQuantum, or other dependencies; those runtimes must remain installed at the recorded locations, and CUDA driver stub directories must never be used as runtime search paths. Use `CMAKE_INSTALL_RPATH` when you need to specify runtime directories explicitly. The default archive configuration keeps relative QuEST paths and does not enable `CMAKE_INSTALL_RPATH_USE_LINK_PATH`; an archive made from the opt-in native build retains its absolute SDK paths and therefore requires that deployment layout. + --------------------------- diff --git a/tests/packaging/CMakeLists.txt b/tests/packaging/CMakeLists.txt index 2a7f1186c..7b51a73fe 100644 --- a/tests/packaging/CMakeLists.txt +++ b/tests/packaging/CMakeLists.txt @@ -13,6 +13,9 @@ if(QUEST_TEST_ARCHIVES AND QUEST_ENABLE_PACKAGING) "-DCONFIG=$" -P "${CMAKE_CURRENT_SOURCE_DIR}/ArchiveConsumer.cmake") set_tests_properties(packaging.archives PROPERTIES LABELS packaging RUN_SERIAL TRUE) endif() +add_subdirectory(rpath) +get_property(_rpath_tests DIRECTORY rpath PROPERTY TESTS) +set_tests_properties(${_rpath_tests} DIRECTORY rpath PROPERTIES LABELS packaging) add_subdirectory(cuquantum) get_property(_finder_tests DIRECTORY cuquantum PROPERTY TESTS) set_tests_properties(${_finder_tests} DIRECTORY cuquantum PROPERTIES LABELS packaging) diff --git a/tests/packaging/check_native_runtime.py b/tests/packaging/check_native_runtime.py new file mode 100644 index 000000000..424694c3a --- /dev/null +++ b/tests/packaging/check_native_runtime.py @@ -0,0 +1,106 @@ +"""Check a Linux shared CUDA/cuQuantum install without modifying it. + +Example (after building the ordinary packaging/consumer fixture): + python3 tests/packaging/check_native_runtime.py --build-dir build \ + --library /opt/QuEST/lib/libQuEST.so --consumer consumer-build/consumer_c \ + --consumer consumer-build/consumer_cpp +""" + +import argparse +import os +from pathlib import Path +import re +import subprocess + + +def run(*command): + # Also remove less common loader controls, including LD_RUN_PATH and LD_AUDIT. + environment = {key: value for key, value in os.environ.items() + if not key.startswith(("LD_", "DYLD_")) + and key not in ("LIBPATH", "SHLIB_PATH")} + result = subprocess.run(command, env=environment, text=True, check=True, + stdout=subprocess.PIPE, stderr=subprocess.STDOUT) + print(result.stdout, end="", flush=True) + return result.stdout + + +def require(condition, message): + if not condition: + raise RuntimeError(message) + + +def dynamic(path): + print(f"Checking ELF dynamic section: {path}", flush=True) + output = run("readelf", "-d", str(path)) + needed = re.findall(r"\(NEEDED\).*\[([^]]+)\]", output) + sonames = re.findall(r"\(SONAME\).*\[([^]]+)\]", output) + search = re.findall(r"\((?:RPATH|RUNPATH)\).*\[([^]]*)\]", output) + paths = [entry for value in search for entry in value.split(":")] + for entry in paths: + require(entry, f"Empty loader search directory in {path}") + require(not is_stub(Path(entry)), f"Stub loader search directory in {path}: {entry}") + return needed, sonames, paths + + +def is_stub(path): + return any(part.lower() in ("stub", "stubs") + for part in (*path.parts, *path.resolve().parts)) + + +def loaded(path, expected): + print(f"Checking loader resolution with loader variables unset: {path}", flush=True) + output = run("ldd", str(path)) + require("not found" not in output, f"Unresolved runtime dependency in {path}") + resolved = dict(re.findall(r"^\s*(\S+)\s+=>\s+(/.*?)\s+\(", output, re.MULTILINE)) + for soname, location in resolved.items(): + require(not is_stub(Path(location)), f"Loader resolved {soname} to a stub: {location}") + for soname, library in expected.items(): + require(soname in resolved, f"{path} did not load {soname}") + require(Path(resolved[soname]).resolve() == library, + f"{path} loaded {soname} from {resolved[soname]}, expected {library}") + + +def main(): + parser = argparse.ArgumentParser(description=__doc__) + parser.add_argument("--build-dir", type=Path, required=True) + parser.add_argument("--library", type=Path, required=True) + parser.add_argument("--consumer", type=Path, action="append", default=[]) + parser.add_argument("--require-shared-cudart", action="store_true") + args = parser.parse_args() + cache = dict(re.findall(r"^([^/#:\r\n][^:\r\n]*):[^=\r\n]+=(.*)$", + (args.build_dir / "CMakeCache.txt").read_text(), re.MULTILINE)) + library = args.library.resolve(strict=True) + needed, sonames, search = dynamic(library) + require(len(sonames) == 1, f"Expected one shared QuEST SONAME in {library}") + search_dirs = {Path(entry).resolve() for entry in search if Path(entry).is_absolute()} + expected = {} + # CUDA's default runtime can be static.
