IW concurrency control

Source: R/DAISIE_loglik_IW.R
DAISIE_IW_num_threads.Rd

Sets or retrieves the number of threads used by the odeint solver.

Usage

DAISIE_IW_num_threads(num_threads)

Arguments

num_threads

num_threads < 0 or omitted: retrieves number of threads.
num_threads = 0: sets the number of threads to the number of available cores.
num_threads = 1: single-threaded execution.
num_threads > 1: sets the number of threads to num_threads.

Value

number of threads

Note

The maximum number of threads is limited to the value of the C++ standard library function std::thread::hardware_concurrency(). This is also the default number of threads upon library load. Multithreading incurs some overhead. Therefore, single-threaded execution might be faster for small systems.
