Communication Detection in Shared Memory (CDSM)

CDSM is a Linux kernel module to detect communication of parallel applications in shared memory, and use that information to migrate threads between cores based on their affinity.

Installation

Compile and insert the CDSM kernel module:

 $ make
 $ make install

Execution

Rename the binary that you want CDSM to handle so that it ends with .x:

 $ ./app.x

Everything else is automatic.
