CholeskyMicrobenchmark: Conducts a single performance trial with the Cholesky...

In RHPCBenchmark: Benchmarks for High-Performance Computing Environments

Description

CholeskyMicrobenchmark conducts a single performance trial of the Cholesky factorization dense matrix kernel for the matrix given in the kernelParameters parameter. The function times the single function call chol(kernelParameters$A).

Usage

CholeskyMicrobenchmark(benchmarkParameters, kernelParameters)

Arguments

benchmarkParameters	an object of type DenseMatrixMicrobenchmark specifying various parameters for microbenchmarking the dense matrix kernel
kernelParameters	a list of matrices or vectors to be used as input to the dense matrix kernel

Value

a vector containing the user, system, and elapsed performance timings in that order

Examples

## Not run: 
# Allocate input to the Cholesky microbenchmark for the first matrix size
# to be tested
microbenchmarks <- GetDenseMatrixDefaultMicrobenchmarks()
kernelParameters <- CholeskyAllocator(microbenchmarks[["cholesky"]], 1)
# Execute the microbenchmark
timings <- CholeskyMicrobenchmark(microbenchmarks[["cholesky"]], kernelParameters)

## End(Not run)
