#!/usr/bin/env bash
# run_sim.sh -- run a CUDA binary on the GreenEye-GPGPU-Sim TU104 scaffold.
#
# Substitutes the CUDA runtime with GPGPU-Sim's libcudart.so via
# LD_LIBRARY_PATH (the mechanism documented in the upstream README, "Step 3:
# Run"), points the simulator at the tracked TU104 scaffold config, and
# executes the binary from a dedicated run directory so simulator output does
# not pollute the source tree.
#
# Development-only tooling: it simulates; it never touches GPU hardware,
# kernel modules, mdev, or a guest.
#
# Usage:
# ./run_sim.sh [--workdir DIR] [--build-type release|debug] <cuda-binary> [args...]
#
# Prerequisites: ./setup.sh has completed a build, and the binary was linked
# with `--cudart shared` so it resolves libcudart.so dynamically.
#
# Outputs (in the work directory, default gpgpu-sim/build/run/):
# gpgpusim.config -> symlink to the tracked TU104 config
# config_turing_islip.icnt -> symlink to the tracked interconnect config
# gpgpusim_out.txt, gpgpu_inst_stats.txt, ... (upstream simulator outputs)

Usage: run_sim.sh [--workdir DIR] [--build-type release|debug] \
[--config-dir DIR] <cuda-binary> [args...]
--workdir DIR directory the binary runs in (default gpgpu-sim/build/run)
--build-type TYPE release (default) or debug
--config-dir DIR config directory to use (default configs/turing-tu104-2080super)
-h, --help this help
The binary must be dynamically linked against libcudart (link with
"--cudart shared"); LD_LIBRARY_PATH is replaced with the GPGPU-Sim runtime
so no recompilation for the simulator is needed.
