Numalize: Detect memory access patterns of parallel applications

Numalize is a memory tracing tool to detect communication (i.e. accesses to shared memory areas) and page usage of parallel applications that use shared-memory APIs (e.g. OpenMP and Pthreads). It is based on the Intel Pin Dynamic Binary Instrumentation (DBI) tool (https://software.intel.com/en-us/articles/pintool/).

Requirements

• Intel Pin installation (https://software.intel.com/en-us/articles/pintool/). The Makefile tries to find your Pin installation in /home and /opt. You can override the path manually in the top of the Makefile. Note that Pin version 3.x is currently required.

Usage

Compile numalize:

$ make

Generate communication pattern:

$ ./run.sh -c -- ./binary

Generate page access pattern:

$ ./run.sh -p -- ./binary
