HPX V1.4.0 (January 15, 2020)

General changes

  • We have added the collectives all_to_all and all_reduce.
  • We have added APIs for resiliency, which allows replication and replay for failed tasks. See the documentation for more details.
  • Components can now be checkpointed.
  • Performance improvements to schedulers and coroutines. A significant change is the addition of stackless coroutines. These are to be used for tasks that do not need to be suspended and can reduce overheads noticeably in applications with short tasks. A stackless coroutine can be created with the new stack size thread_stacksize_nostack.
  • We have added an implementation of unique_any, which is a non-copyable version of any.
  • The shared_priority_queue_scheduler has been improved. It now has lower overheads than the default scheduler in many situations. Unlike the default scheduler it fully supports NUMA scheduling hints. Enable it with the command line option --hpx:queuing=shared-priority. This scheduler should still be considered experimental, but its use is encouraged in real applications to help us make it production ready.
  • We have added the performance counters background-receive-duration and background-receive-overhead for inspecting the time and overhead spent on receiving parcels in the background.
  • Compilation time has been further improved when HPX_WITH_NETWORKING=OFF.
  • We no longer require compiled Boost dependencies in certain configurations. This requires at least Boost 1.70, compiling on x86 with GCC 9, clang (libc++) 9, or VS2019 in C++17 mode. The dependency on Boost.Filesystem can explicitly be turned on with HPX_FILESYSTEM_WITH_BOOST_FILESYSTEM_COMPATIBILITY=ON (it is off by default if the standard library supports std::filesystem). Boost.ProgramOptions has been copied into the HPX repository. We have a compatibility layer for users who must explicitly use Boost.ProgramOptions instead of the ProgramOptions provided by HPX. To remove the dependency HPX_PROGRAM_OPTIONS_WITH_BOOST_PROGRAM_OPTIONS_COMPATIBILITY must be explicitly set to OFF. This option will be removed in a future release. We have also removed several other header-only dependencies on Boost.
  • It is now possible to use the process affinity mask set by tools like numactl and various batch environments with the command line option --hpx:use-process-mask. Enabling this option implies --hpx:ignore-batch-env.
  • It is now possible to create standalone thread pools without starting the runtime. See the standalone_thread_pool_executor.cpp test in the execution module for an example.
  • Tasks annotated with hpx::util::annotated_function now have their correct name when using APEX to generate OTF2 files.
  • Cloning of APEX was defective in previous releases (it required manual intervention to check out the correct tag or branch). This has been fixed.
  • The option HPX_WITH_MORE_THAN_64_THREADS is now ignored and will be removed in a future release. The value is instead derived directly from HPX_WITH_MAX_CPU_COUNT option.
  • We have deprecated compiling in C++11 mode. The next release will require a C++14 capable compiler.
  • We have deprecated support for the Vc library. This option will be replaced with SIMD support from the standard library in a future release.
  • We have significantly refactored our CMake setup. This is intended to be a non-breaking change and will allow for using HPX through CMake targets in the future.
  • We have continued modularizing the HPX library. In the process we have rearranged many header files into module-specific directories. All moved headers have compatibility headers which forward from the old location to the new location, together with a deprecation warning. The compatibility headers will eventually be removed.
  • We now enforce formatting with clang-format on the majority of our source files.
  • We have added SPDX license tags to all files.
  • Many bugfixes.

Breaking changes

  • The HPX_WITH_THREAD_COMPATIBILITY option and the associated compatibility layer has been removed.
  • The HPX_WITH_INCLUSIVE_SCAN_COMPATIBILITY option and the associated compatibility layer has been removed.
  • The HPX_WITH_UNWRAPPED_COMPATIBLITY option and the associated compatibility layer has been removed.
