Run time data

Run times measured on an Intel(R) Xeon(R) CPU X5680 clocked at 3.33 GHz with 12 MB cache, running RedHat Enterprise Linux, R 3.2.3 and gcc 4.8.5, using version 0.4 of the wrswoR package. The data are created by the corresponding scripts in the data_raw directory.

timings_sort

Format

An object of class data.frame with 25200 rows and 5 columns.

A data frame with 5 columns:

prob

A description of the probability distribution used. See data_raw/benchmark.R for details.

expr

Function name without the sample_int_ prefix.

time

Run time in nanoseconds, as measured by microbenchmark::microbenchmark()

r

Ratio between the size and n arguments.

n

The n argument.

Details

timings contains run times for a larger range of values for the n argument.

timings_sort contains run times for sorting probabilities with the given distributions.

break_even contains detailed run times for the analysis of break-even points between the various implementations.
