+# 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)
