 Set the otuput file
 Return 0 on success, -1 on error

 Set the output file
 Return 0 on success, -1 on error

 Close output file

 Perform the CPU run
 Return 0 on success, -1 on error

 Perform the CPU run scanning over the number of workers per node
 Return 0 on success, -1 on error

 Draw the CPU speedup plot.

           2           fit with the relevant '2nd degree related' function
           3           fit with varying rcpu function
     n0 = for dofit == 3, number of real cores
     n1 = for dofit == 3, number of total cores (real + hyperthreaded)

 Get from TDirectory 'd' the TProfile named 'pfn' and create the graph.
 Return also the max y in mx.

 Make sure that the fitting functions are defined

 Get performance specs. Check file 'path', or files in directory 'path'
 (default current directory).
 The degree of the polynomial used for the fit is 'degfit' (default 1).

 Perform a test using dataset 'dset'
 Return 0 on success, -1 on error
 Open the file for the results

  dofit =  0           no fit
           1           fit with default 3 parameter saturated I/O formula
           2           fit with 4 parameter saturated I/O formula (varying Rcpu)
     n0 = for dofit == 2, number of real cores
     n1 = for dofit == 2, number of total cores (real + hyperthreaded)

 Draw the efficiency plot.
  opt = 'cpu' or 'data' (default the first found)

 Release memory cache for dataset 'dset'
 Return 0 on success, -1 on error

 Physically remove the dataset 'dset', i.e. remove the dataset and the files
 it describes
 Return 0 on success, -1 on error

 Create the largest dataset for the run.
 Defaults for
          dataset name, filename root
 are
          "BenchDataSet", "event"
 respectively.
 These can be changed via dset and fnroot, respectively.
 The string 'fnroot' defines the location of the files, interpreted as an URL.
 Examples:
          fnroot             files
          'event'            <datadir>/event_<ord>_<#>.root
          '/mss/event'       /mss/event_<ord>_<#>.root
          'root://srv//mss/event?remote=1'
                             root://srv//mss/event_<ord>_<#>?remote=1.root
 Default selector is TSelEventGen. Use SetDataGenSel and SetDataGenPar to change it
 and to pass the list of PARs defining the alternative selector.
 The argument 'nevt' controls the number of events per file (-1 for the default,
 which is 30000).
 Return 0 on success, -1 on error

 Copy the files of dataset 'dset' to 'destdir' and create a new dataset named 'dsetdst'
 decribing them.
 Return 0 on success, -1 on error

 Set the PROOF instance to be used for dataset operations, like releasing
 cache ...
 Use SetProofDS(0) to reset and using the default PROOF
