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

• Release for JSS publication https://doi.org/10.18637/jss.v097.c01.

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.
