Description

Utility functions for GPU/CPU Benchmarking

Usage

requirements()
  createDatabase(dbfile) databaseResult(data,dbfile)
  installAtlas() installAtlas39() installGoto() installMKL() purgeAtlas() purgeAtlas39() purgeGoto() purgeMKL()
  isPackageInstalled(package) hasGputools()
  getBenchmarkData(host)

Arguments

data

a (one-row) dataframe containing results from a benchmark

dbfile

character string containing path and name of SQLite database file

package

character string denoting a package to test for

host

character string denoting the host system for which benchmark data is to be retrieved

Details

requirements checks for a few system requirements such platform (Unix), operating system provider (Debian or Ubuntu) and presense of key packages (gotoblas2-helper).

createDatabase creates an empty SQLite database to store benchmark results.

databaseResult stores the benchmark results in the SQLite database.

The different install* functions add the respective BLAS libraries to the system; the different purge* functions do the inverse operation and remove them.

The function hasGputools tests for presence of this CRAN package on the current machine -- as a very cheap proxy to testing whether the machine in GPU-capable or not. It uses the function isPackageInstalled for this test.

The function getBenchmarkData retrieves benchmark results for a given host.
