Logs of Real Parallel Workloads from Production Systems

The original logs come in different formats. Information about the individual format for each log is given to the degree available in the log's associated notes document. In addition to the original format, all logs are converted to the Standard Workload Format (SWF). Some of the logs also have cleaned versions; it is recommended that these be used when available.

To promote reproducibility, files are named according to the following convention. Each file name has two parts, identifying the dataset and the file version. The dataset identifier is constructed as <site>-<machine>-<year>. The version is a serial number and possible modifier. Number 0 is reserved for the original (unconverted) version. The number is increased by 1 for each new conversion (in case errors were found in a conversion and additional conversions were performed). Modified versions are indicated by a minor number. Thus a file name of CTC-SP2-1996-2.1-cln.swf is based on the dataset CTC-SP2-1996 (log of the SP2 machine at CTC starting from 1996), and represents a cleaned version of conversion 2 of this dataset. When using these logs, please specify exactly which file you are using, in order to enable others to reproduce your work.

get a list of the current (cleaned) versions of all logs, useful for downloading with wget -i

	= Important notes associated with log
	= File to download
Mon	= Duration of log in months
UE	= Indicates whether log contains user runtime estimates    [You can add artificial estimates to logs that lack them by using this utility]
Mem	= Indicates whether log contains data about memory (requested or used)
Util%	= Utilization expressed as percentage

The ORIGNAL SWF files reflect the data "as is", with only minor modifications to make them self-consistent (for example, jobs that seem to start before they arrive are modified to equate the arrival and start times). Regrettably, the data often includes problematic and unrepresentative data, such as significant automated administrative activity or large-scale flurries of activity by single users. In order to ease the use of these logs in performance evaluations, we therefore also provide a CLEANED version of the logs, and recommend that this version be used (of course, you are urged to make your own decision regarding what cleaning if at all should be applied, but if you don't want to get into this, we suggest you use ours). Specific information about the cleaning performed on each log is detailed in the "usage notes" section of the log's notes document. Further information about identifying and justifying the removal of problematic and unrepresentative data may be found in:
