Prism

The intuitive, event-driven application profiling and characterization framework.

Install

C++14 compiler support is required
cmake v3 required
See CentOS 7 Support

git clone https://github.com/vandal/prism
cd prism
mkdir build && cd build
cmake ..
make -j

The executable will be put in build/bin. It can be run in place, or the folder can be moved to an install location.

What is it?

Uses a straight-forward intermediate representation (IR) for system architecture and application behavior studies.
Prism provides the dynamic behavior of an application with 4 event primitives:

• Compute - IOPs & FLOPs
• Memory - data access
• Synchronization - task-level create, join, sync, et al
• Context - markers for basic blocks, subroutines, instructions, etc
• Control Flow support is pending community demand

Each event has specific attributes that are accessible via the Prism API

Example Usage

• Valgrind is the default frontend for generating events, if no option is specified
• SynchroTraceGen backend processing events into a special event trace

$ bin/prism --backend=stgen --executable=./myprogram -with --args

Users supply at least 2 arguments to Prism:

• the backend analysis tool used to process events
• the application

A third frontend argument can be supplied

• --frontend=FRONTEND
• --frontend=dynamorio is experimental

Platform support
