WriteSparseMatrixPerformanceResultsCsv: Appends sparse matrix performance test results to a file in CSV format

Description

WriteSparseMatrixPerformanceResultsCsv appends performance results for a single sparse matrix performance test to a CSV file.

Usage

WriteSparseMatrixPerformanceResultsCsv(numberOfThreads, numberOfRows,
  numberOfColumns, numberOfNonzeros, averageWallClockTime, standardDeviation,
  csvResultsFileName)

Arguments

numberOfThreads
the number of threads all of the performance trials were conducted with
numberOfRows
the number of rows in the matrix
numberOfColumns
the number of columns in the matrix
numberOfNonzeros
the number of non-zero elements in the matrix
averageWallClockTime
average wall clock time computed for the matrix tested during the performance trials
standardDeviation
standard deviation of the wall clock times obtained for the performance trials
csvResultsFileName
the CSV results file the performance result will be appended to

Details

This function appends the performance results obtained by a single sparse matrix microbenchmark conducted for a specific matrix. If the CSV file does not exist, header information is printed on the first line to describe the subsequent entries. Each entry consists of the dimension parameter used to specify the dimensions of the matrix, the average of the wall clock times obtained for the performance trials, the standard deviation of the performance trial wall clock times, and the number of threads the performance trials were conducted with.
