DataToSWF: Convertor from a dataframe to Standart Workload Format

Description

Note that this is only a wrapper for the ToSWF command with a dataframe argument. It needs a correctly built dataframe and converts it to a Standart Workload Format used to share the logfiles of High Performance Clusters

Usage

DataToSWF(Frame, filename="output.swf")

Arguments

Frame

A dataframe containing the variables needed by ToSWF function.

filename

The file to store the converted workload (output.swf by default)

Value

Nothing is returned, but a file is created in the current working directory (with default name output.swf) containing the converted data.

Details

The Standart Workload Format is a single format to store and exchange high performance cluster logs, that is used in Parallel Workload Archive. See references for current standard. The SWF format may contain additional data, but in this package only the 1st to 5th fields are used. One may also need to manually fill in the header of the file in order to completely prepare the resulting SWF file.
