In RcppParallel: Parallel Programming Tools for 'Rcpp'

RcppParallel 5.1.7

• Remove deprecated std::iterator. (#192; @Enchufa2)

RcppParallel 5.1.6

• Patch for TBB to allow compilation with gcc-13.

• 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

• Fixed an issue that prevented compilation of RcppParallel with R (< 4.0.0) of R on Windows.

• The RCPP_PARALLEL_USE_TBBMALLOC_PROXY environment variable can now be used to control whether RcppParallel loads the tbbmalloc_proxy library on load. See https://www.threadingbuildingblocks.org/docs/help/tbb_userguide/Automically_Replacing_malloc.html for more information.

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
