pjbb2005

pjbb2005 is a fixed-workload variant of the SPECjbb2005 Java benchmark. Fixing the workload to a constant amount of work (rather than a fixed period of time) makes the benchmark more manageable as a research tool.

To use pjbb2005, you will first need to license jbb2005 from SPEC.

Building and Running

1. Download the pjbb patch.

2. Patch the SPECjbb2005 sources:

   cd SPECjbb2005
   chmod -R u+w src
   patch -p1 < ../pjbb2005-1.1.patch
   

3. Build the suite:

   ant
   

4. Run:

   java -cp build/dist/jbb.jar:build/dist/check.jar spec.jbb.JBBmain -propfile SPECjbb-8x50000.props -n 2
   

5. Install the dist directory to the location of your choice:

   cp -a build/dist <location of your choice>
   

Features

pjbb2005 extends/modifies SPECjbb2005 in the following ways:

1. to run for a fixed number of transactions (rather than fixed time)
2. to run a number of iterations of the benchmark (specified using the “-n” flag)
3. to call a user-defined callback method at the start and end of each iteration (specified using the “-c” flag)
4. to use a temporary directory for all generated output (so that the benchmark directory can be read-only)
5. to allow the benchmark to be run from a directory other than the benchmark root
