 2. **Accel-Sim SASS Frontend and Simulation Engine**: A simulator frontend that consumes SASS traces and feeds them into a performance model. The intial release of Accel-Sim coincides with the release of [GPGPU-Sim 4.0](https://github.com/accel-sim/accel-sim-framework/blob/dev/gpu-simulator/gpgpu-sim4.md), which acts as the detailed performance model. To build the Accel-Sim simulator that uses the traces, do the following:
     ```bash
+    pip3 install -r requirements.txt
     source ./gpu-simulator/setup_environment.sh
     make -j -C ./gpu-simulator/

Please look at the *opcode.h* files for respective GPU Architectures in the same directory `gpu-simulator/ISA_Def/` for SASS instruction to Accel-Sim opcode mapping.
