Sniper Features

Simulator features

• Interval model: a fast, high-abstraction level core simulation model using the interval model
• CPI stack generation
• x86-64 architecture support
• Python scripting support (DVFS control, etc.)
• OpenMP support
• Simulation statistics collection (sim.stats)
  • Support scripts for parsing and understanding statistics
• ROI (region of interest) support
• Multi-OS support (RedHat, Ubuntu, Debian support/gcc 4.3 or higher)
• Easy debugging of the simulator, and applications running in Pin (--gdb, --appdebug)
• Multiple instrumentation modes
  • Faster cache-only pre-ROI simulation before detailed simulation
• Stackable configurations
  • Example: Use the nehalem microarchitecture with the big-cache configuration ("-c nehalem -c big-cache")

Hardware features

• Accurate core model [ ref,pdf ]
• Parametric shared cache model
• Modern Pentium-M-style branch predictor [ ref ]
