===== Benchmarks =====

We are distributing a set of benchmarks that work with gem5-gpu, including:

  * Minimally modified Rodinia workloads
  * Minimally modified Parboil workloads
  * Rodinia no copy benchmarks, which elide memory copies and instead rely on coherence to transfer data between the CPU and GPU
  * Demystifying CUDA benchmarks: microbenchmarks based on the [[http://www.stuffedcow.net/research/cudabmk|Demystifying GPU Microarchitecture through Microbenchmarking]] paper
  * Unit tests

==== Obtaining Benchmarks ====
<code>
hg clone https://gem5-gpu.cs.wisc.edu/repo/benchmarks/
</code>

This will create a repository, with sub-repositories, including:
  * common: includes a makefile for compiling CUDA code to run inside gem5-gpu
  * dcmbmk: Demystifying GPU Microarchitecture benchmarks
  * libcuda: A version of libcuda that benchmarks are linked with when being compiled to run in gem5-gpu
  * parboil: Parboil benchmarks
  * rodinia: Rodinia benchmarks
  * rodinia-nocopy: Rodinia benchmarks with memcpy api calls elided
  * unittests: A set of simple tests for validating gem5-gpu

==== Compiling Benchmarks ====
gem5-gpu works with cuda 3.1. Please install this on your system before proceeding further.

=== Compile libcuda ===
<code>
[gem5-gpu] cd libcuda
[gem5-gpu/libcuda] make
</code>


=== Example of Compiling a Benchmark ===
<code>
[gem5-gpu] cd Rodinia/nw
[gem5-gpu/Rodinia/nw] make
</code>

== Example of Compiling a Benchmark ==
Test that the benchmark executes:
<code>
...
