New features

  • The CUDA/HIP pool uses fewer, and a user-controllable number of, cuBLAS/SOLVER and rocBLAS/SOLVER handles. This can significantly reduce GPU memory usage, especially on high core count systems. (#1234)
  • The sender adaptor transfer has been renamed to continues_on, with a deprecation warning, to match the latest P2300 proposal. transfer_just and transfer_when_all have been deprecated. (#1235)

Breaking changes

Bugfixes

  • An initialization issue when setting an explicit process mask on a process that has a limited number of cores available due to cgroups restrictions has been fixed. (#1251)

New features

Breaking changes

  • When using stdexec, pika now requires and is tested with stdexec commit 8bc7c7f06fe39831dea6852407ebe7f6be8fa9fd. (#1205)
  • The Boost dependency is now found using CMake's config mode instead of CMake's deprecated Boost module. This requires Boost to be installed with a BoostConfig.cmake file. (#1229)

Bugfixes

  • NUMA nodes and sockets are now correctly handled on Grace-Hopper systems. This allows use of hwloc 2.11 and newer on such systems. (#1224)

New features

  • sync_wait now internally uses a binary_semaphore instead of a condition_variable for synchronization and may be slightly faster due to removing one lock. (#1206)

Breaking changes

  • All channel implementations have been removed. (#1209)

Bugfixes

  • Compilation of copyable senders together with when_all_vector has been fixed. (#1200)
  • The pika/execution.hpp header has been fixed to include headers that should have been included by it. (#1206)

New features

  • Handling of receivers has been slightly optimized internally to avoid allocations. (#1126, #1139, #1192)
  • The MPI integration now has experimental support for the MPI continuations proposal. This requires an experimental build of OpenMPI. (#1128)
  • pika can now be compiled as a static library by disabling the CMake option BUILD_SHARED_LIBS. (#1179)

Breaking changes

  • The shared_mutex utility has been removed. (#1155)
  • The prefix module has been cleaned up with many internal functionalities being moved to a detail namespace. (#1177)
  • The depleted thread state has been removed as it is no longer used. (#1184)

Bugfixes

  • The hostname output in logs has been fixed. (#1127)
  • The internal append_t type pack helper has been fixed to append rather than prepend. This may affect the order of completion signatures for senders. However, there are still no guarantees on the order of completion signatures. (#1137)
  • Fix potential use-after-free in MPI integration. (#1151)
  • Undefined behaviour on FreeBSD in the get_executable_prefix helper has been fixed. (#1171)
  • Compilation with PIKA_WITH_STACKTRACES=OFF has been fixed. (#1178, #1196)

New features

  • The MPI polling functionality has been significantly refactored and optimized. (#1102)
  • pika's senders and receivers now use the newer sender and receiver concepts when defined by stdexec. (#1105)

Breaking changes

  • The pika logging facilities have been refactored to use spdlog. The new behaviour is described in the pull request and documentation (#1093)
  • The runtime module has been cleaned up with many functionalities being removed or moved to the detail namespace. (#826, #1091)

Bugfixes

  • Builds with the CMake option PIKA_WITH_THREAD_DEBUG_INFO enabled have been fixed. (#1101)

New features

  • Avoid unnecessary copies of CUDA streams and handles to improve profiling appearance. (#1056)
  • Avoid use of std::invoke_result in tag_invoke_result variants to improve compilation times. (#1058, #1060)

Breaking changes

Bugfixes

  • Fix use of --pika:print-bind with --pika:bind=none. (#1082, #1087)
  • Work around compilation issue with CUDA 12.4. (#1084)
