When measuring executable sizes, this is the binary.\n* The `redis-cli` program can be used as a command-line client.\n* Compile flags should be changed in `src/Makefile`.\n\n### Memcached\n\n* Use `./configure` to add compile flags\n* `echo \"flush_all\" | nc localhost 11211` should work as your 'clear' command in the YCSB script.\n\n### MongoDB\n\n* `mongo ycsb --eval \"db.dropDatabase()\"` should drop the YCSB database for use in the YCSB script.\n* I just used the `install-mongod` and `install-mongo` targets to get the server and CLI client, respectively; you shouldn't need to build any other targets.\n\n### Clang\n\n* Follow [this guide](https://clang.llvm.org/get_started.html) to build clang properly.\n\n### GCC\n\n* Refer to Tanvir's \"[C++ systems and their benchmarks of performance evaluation](https://docs.google.com/document/d/1ZPYYSQDf_syft2VQtuxxrqCUNiB0f13dusvcjo6KAoc/edit?ts=5f53dda7)\" on how to build GCC from source.\n* Before running `./configure`, modify it to add the compile flags you need.\n\n### RocksDB\n\n* Follow [this guide](https://github.com/facebook/rocksdb/blob/master/INSTALL.md) to compile RocksDB\n* Edit the compile flags by editing `./Makefile`, and use the `PREFIX` to mark the installation directory.\n* Build only the static library via `make static_lib`, as other `make` commands install other, unnecessary tools.\n* To better compare stack-unwinding performance impacts on RocksDB against other NoSQL database applications, we recommend using the YCSB benchmark for RocksDB as opposed to its own benchmarking program.\n\n### FFmpeg\n\n* Download and unzip [vbench](http://arcade.cs.columbia.edu/vbench/). \n* In the top directory, run `export VBENCH_ROOT=$(pwd)`\n* Run `./install-reference-ffmpeg.sh` for vbench to download all the repositories necessary to build FFmpeg.\n* For each new build of FFmpeg, delete or rename the existing `./bin/ffmpeg`, modify `./ffmpeg_sources/ffmpeg/configure` to add compile flags, and then re-run `./install-reference-ffmpeg.sh`\n* To create a benchmark, modify the \"perform transcoding\" section of `./code/reference.py` to include a for-loop and a filter for whichever video files (found in `./crf0` and `./crf18`) you would like to transcode.\n* Then, run the benchmark script with `python code/reference.py scenario` where `scenario` can be any of the following: `live`, `upload`, `platform`, `popular`, or `vod`","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fefeslab%2Fstack-unwind","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fefeslab%2Fstack-unwind","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fefeslab%2Fstack-unwind/lists"}
