To launch drmemtrace, use the -t flag to drrun and specify the drmemtrace framework where the default tool to run is the cache simulator:

$ bin64/drrun -t drmemtrace -- /path/to/target/app <args> <for> <app>

The target application will be launched under a DynamoRIO tracer client that gathers all of its memory references and passes them to the simulator via a pipe. (See Offline Traces and Analysis for how to dump a trace for offline analysis.) Any child processes will be followed into and profiled, with their memory references passed to the simulator as well.

Here is an example:

$ bin64/drrun -t drmemtrace -- ~/test/pi_estimator
Estimation of pi is 3.142425985001098
---- <application exited with code 0> ----
