RcppParallel 5.1.6 (UNRELEASED)

  • Fixed a memory leak that could occur when using TinyThread on POSIX systems. (#185; @dipertix and and @kevinushey)

RcppParallel 5.1.5

  • Patches to ensure compatibility with the R 4.2.0 UCRT toolchain on Windows, adapted from patches contributed by Tomas Kalibera.

  • Fixed an issue where setting TBB_ROOT (or TBB_INC / TBB_LIB) would copy rather than symlink the associated libraries. (#161)

RcppParallel 5.1.4

  • Fixed an issue causing client packages of RcppParallel to fail to compile on Solaris.

RcppParallel 5.1.3

RcppParallel 5.1.2

  • RcppParallel gains the tbbLibraryPath() function, to be used when attempting to query the location of the TBB libraries that RcppParallel has been configured to use. This may be useful for R packages which wish to explicitly use, or link to, these libraries.

RcppParallel 5.1.1

  • Updated bundled version of TBB (Intel TBB 2019 Update 8).

  • RcppParallel can now be configured to use an external copy of TBB, via the TBB_LIB and TBB_INC environment variables. These should be set to the directories containing the TBB libraries and headers, respectively.

  • Added support for the latest versions of Intel oneAPI TBB / oneTBB.

  • Updated TBB functionality for the new interface.

  • Falling back to building TBB from local source code.

  • Backward TBB compatibility based on __TBB_tbb_stddef_H.

  • Resolved conflicts between system and local TBB headers.

  • Fixed URLs, used HTTPS, and minor cleanups.

  • Updated package DESCRIPTION and bumped version.

  • setThreadOptions(...) can again be called multiple times per session. The requested number of threads will be used for invocations to parallelFor() and parallelReduce() that don't explicitly request a specific number of threads.

  • The parallelFor() and parallelReduce() functions gain the numThreads argument, allowing one to limit the number of threads used for a particular computation.

RcppParallel 5.0.3

  • Fixed compilation on macOS M1 machines.

RcppParallel 5.0.2

  • setThreadOptions(...) can now only be called once per session, to avoid segfaults when compiling RcppParallel / TBB with gcc 10.1. Subsequent calls to setThreadOptions(...) are ignored.

RcppParallel 5.0.1

  • Fixed compilation issue on OpenSUSE Tumbleweed with -flto=auto

  • Fixed compilation when CPPFLAGS = -I/usr/local/include and a version of libtbb is installed there

RcppParallel 5.0.0

  • RcppParallel backend can now be customized with RCPP_PARALLEL_BACKEND environment variable (supported values are 'tbb' and 'tinythread')

  • Fixed issue when compiling RcppParallel on macOS Catalina

  • Fixed issue when compiling RcppParallel with Rtools40

RcppParallel 4.4.4

  • Fixed an issue when compiling RcppParallel with clang-9 on Fedora

RcppParallel 4.4.3

  • Suppress gcc-9 warnings related -Wclass-memaccess

  • Added TBB headers for serial TBB operations (#90, @mikejiang)

  • Fixed row iterator constructor (#87, @wtianyi)

  • Fixed compilation on FreeBSD

RcppParallel 4.4.2

  • Suppress gcc-8 warnings related to -Wclass-memaccess

  • Use PKG_CXXFLAGS rather than PKG_CPPFLAGS

  • Remove unused dependency on the BH package

RcppParallel 4.4.1

  • Ensure user-specified R configuration passed to TBB

  • Work around warnings emitted by gcc 8

RcppParallel 4.4.0

  • Respect user-defined compiler settings (e.g. from ~/.R/Makevars).

  • Remove TBB's attempts to suppress compiler diagnostics.

  • Allow setting the number of threads to use via RCPP_PARALLEL_NUM_THREADS environment variable.

  • Update to TBB 2018 Update 1.

  • Add native registration of compiled functions.

RcppParallel 4.3.20

  • Add support for Rtools 3.3 w/ GCC 4.9

RcppParallel 4.3.14

  • Add support for TBB on Solaris

  • Fix failure to compile on OS X Snow Leopard R toolchain

  • Add const and non-const operator[] for RMatrix class

RcppParallel 4.3.8

  • Add tbbmalloc library

  • Correctly pass clang to TBB configure when R is using clang

RcppParallel 4.3.6

  • Support for TBB on Windows

RcppParallel 4.3.3

  • Update to TBB 4.3 (fixes clang compilation error in platform.h)

  • Forward CXX to TBB Makefile

RcppParallel 4.2.5

  • Initial release
