Re-aim7

Re-aim7 is a rework of the AIM benchmark suite for the Linux community. The original AIM benchmark was developed to measure operating systems that feature multi-user environments.

Configuration

Compiling

You'll need automake, autoconfig and libaio-dev installed.

Running

There are several different possible workload files. A link will be provided for the workfile that was used to produce the results.

Interpretation

The horizontal axis is essentially the number of simultaneous jobs, the vertical axis the overall rate at which the jobs complete. For a perfectly scalable system, the curve should look like this:

Note that throughput is proportional to workload until a resource runs out; increasing that resource increases both the workload that can be handled and the peak throughput. On a badly behaved system, throughput can drop with increasing workload; on a well-behaved system it is approximately constant.
