RcppThread (development version)

RcppThread 2.2.0

NEW FEATURE

  • Added RMatrix class (from the RcppParallel package) to allow for thread safe access to R matrices (#74, thanks @rorynolan).

BUG FIX

  • Fixed compilation warning about R_NO_REMAP being defined multiple times (#77, thanks @tylermorganwall)

RcppThread 2.1.7

BUG FIX

  • enable check for standalone libatomic on Windows (#72, thanks @kalibera)

RcppThread 2.1.6

NEW FEATURES

  • allow custom message in ProgessCounter (thanks @tylermorganwall)

RcppThread 2.1.5

BUG FIX

  • Fixes static lifetime issue on MacM1.

RcppThread 2.1.4

BUG FIX

  • Fixes order of headers in detectCores.cpp.

REQUIREMENTS

  • Remove Systemrequirements: C++11

RcppThread 2.1.3

BUG FIX

  • Fixes clang-14 warning about bitwise & with Boolean operands.

RcppThread 2.1.2

NEW FEATURE

  • R function LdFlags() to portably generate linker flags for libatomic/pthread. See README for details.

RcppThread 2.1.0

NEW FEATURE

  • safe printing to the R error stream with RcppThread::Rcerr (#60, thanks to @appelmar).

BUG FIX

  • adapt thread affinity to possibly restricted CPU set (#61).

RcppThread 2.0.1

BUG FIX

  • safeguard construction of memory aligned objects.

RcppThread 2.0.0

NEW FEATURES

  • Add R function detectCores() (#48).

  • Add classes ProgressCounter and ProgressBar for tracking progress in long- running loops (#49).

  • Increased speed due to work-stealing and lock-free pops (#51, #52, #53).

  • Free-standing parallelFor() and parallelForEach() functions now dispatch to a global thread pool that persists for the entire session. This significantly speeds up programs that repeatedly call these functions. (#54)

  • New free-standing push(), pushReturn()/async(), and wait(), mirroring functionality from ThreadPool. (#56)

  • Option to resize a thread pool (#56).

RcppThread 1.0.0

RcppThread 0.5.4

  • Fixed warning for move constructor in ThreadPool (#35, #36, thanks @asardaes for noticing).

RcppThread 0.5.3

  • Improved handling of exceptions thrown from threads.

RcppThread 0.5.2

  • Limit number of threads in unit tests.

  • Fixed typos in package vignette.

RcppThread 0.5.1

BUG FIXES

  • Fix portability issues related to native_handle_type.

  • Fix signed/unsigned comparison in parallelFor().

  • Fix signed/unsigned warnings in unit tests.

RcppThread 0.5.0

DEPENDENCIES

  • Rcpp is no longer a hard dependency, but only used for unit tests. This avoids unnecessary compilation time during package installation.

NEW FEATURES

  • New vignette available, see browseVignettes("RcppThread").

  • New functions parallelFor() and ForEach() allowing parallel for loops with load balancing. Can also be called as method of a ThreadPool.

  • Options to override std::thread and std::cout with RcppThread equivalents using preprocessor variables RCPPTHREAD_OVERRIDE_THREAD and RCPPTHREAD_OVERRIDE_COUT.

  • Several minor performance optimizations.

RcppThread 0.4.0

NEW FEATURE

  • New function ThreadPool::map() that allows to map a function a list of items.

RcppThread 0.3.0

NEW FEATURE

  • A ThreadPool can now be instantiated with zero threads in the pool. It will then do all work pushed to it in the main thread.

RcppThread 0.2.0

NEW FEATURE

  • ThreadPool has a new method wait() that waits for all jobs to be done without joining the threads. This way the thread pool can be re-used for different types of tasks that need to be run sequentially.

RcppThread 0.1.3

BUG FIX

  • Don't check print output of multi-threaded code b/c of random results.

RcppThread 0.1.2

DEPENDS

  • Now available for R (>= 3.3.0).

BUG FIX

  • Fixed a randomly failing unit test.

RcppThread 0.1.1

BUG FIX

  • Default initialize static Rcout instance in header file (#9; couldn't link shared library on r-hub, see discussion in #8)

RcppThread 0.1.0

  • Initial release.
