Cirrus

Cirrus is a remote data access system for interacting with disaggregated memory from uInstances in a performant fashion.

Requirements

This library has been tested on Ubuntu >= 14.04 as well as MacOS 10.12.5. Additional Mac requirements and instructions are listed below.

It has been tested with the following environment / dependencies:

• Ubuntu 14.04
• g++ 5.4
• Boost
• autotools
• Mellanox OFED 3.4 (optional)
• cmake
• cpplint
• snappy
• bzip2
• zlib

You can install these with

$ sudo apt-get update && sudo apt-get install build-essential autoconf libtool g++-6 libboost-all-dev cmake libsnappy-dev zlib1g-dev libbz2-dev && sudo pip install cpplint

MacOS Requirements

Building on MacOS requires the installation of gettext, boost and wget. Please ensure that automake, autoconf, xcode command line tools, and gcc/g++ are installed. gcc/g++ can be installed using macports, and the port select command allows you to set the new version of gcc/g++ as the one you want to use. The remaining programs can be installed using homebrew. cpplint can be installed via pip.

gettext can be installed as follows using homebrew:

$ brew install gettext
$ brew link --force gettext

To install wget do:

$ brew install wget

To install gcc/g++ do:

$ port install gcc5
$ port select --list gcc

To install boost do:

$ sudo port install boost

To install cpplint do:

$ pip install cpplint

Building

$ ./boostrap.sh
$ make

Running Tests

To run tests, run the following command from the top level of the project:

$ make check

To create additional tests, add them to the TESTS variable in the top level Makefile.am . Tests are currently located in the tests directory. To change the ip address (necessary for RDMA), change the address in tests/test_runner.py.

Benchmarks

To run benchmarks execute the following command from the top of the project directory

$ make benchmark

This will leave log files for each benchmark run in the top directory. To add additional benchmarks, modify the script run_benchmarks.py, located in the benchmarks directory. The benchmarks are currently set to run locally, but may be set to run using a remote server by manually changing the ip address in the benchmark files. However, this then makes it so that the benchmarks must be manually launched from the command line after starting the server remotely. Additionally, the log files will be left in the benchmarks directory.
