This is the hackathon repo. If you're reading this through a webhackathon window or a hackathon SSH session, then you're probably looking at your own private copy of the repo. This repo contains the slides and examples used during the 2019-08-23 Persistent Memory Programming Hackathon at the Flash Memory World 2019, in HangZhou. It is provided permanently for reference on GitHub: https://github.com/pmemhackathon/2019-08-23 The PDF files at the top level contain slides: slides.pdf -- essential hackathon background pmdk-overview.pdf -- overview of Persistent Memory Development Kit libpmemobj.pdf -- overview of libpmemobj (C API) libpmemobj-cpp.pdf -- overview of libpmemobj (C++ API) The examples are in examples/A, exmamples/B, etc. Each example is meant to show a persistent memory programming concept, like transactions, support for a specific language, and API, etc. The idea is to use the first few examples (A through C) to gain some essential background knowledge, then pick examples that are interesting to you. Use them as a starting point, or a reference as you develop your own persistent memory aware programs. There's a README.txt file in each example directory that explains what the example is all about. For more information, contact andy.rudoff@intel.com or post your question to the "pmem" google group on groups.google.com. The containers used during the hackathons have all the necessary libraries installed in them. You can access the container directly on DockerHub in the "pmemhackathon" area. Here are the steps taken to install the libraries on a Linux machine. These steps assume you have a machine with persistent memory installed and a recent Linux distro that supports persistent memory. We don't show the ipmctl and ndctl commands used to configure the persistent memory. These examples assume persistent memory is available as a DAX mounted filesystem at "/pmem" on your system. The following link provides more details about the steps to configure persistent memory: https://docs.pmem.io/getting-started-guide # # To clone this repo, use something like the command below. # (Examples assume cloning in your home directory, hence the "cd") # cd git clone https://github.com/pmemhackathon/2019-08-23 # # Some of the examples use PMDK. Many distros include PMDK, but # it takes some time for the latest version to flow intro the distros # so here are the steps to build the latest source and install it in # the usual locations on Fedora 30. # cd # ubuntu: sudo apt-get install autoconf pkg-config libndctl-dev libdaxctl-dev sudo dnf install autoconf pkg-config ndctl-devel daxctl-devel git clone https://github.com/pmem/pmdk cd pmdk make sudo make install prefix=/usr # # Also install the C++ bindings for libpmemobj for the C++ example. # cd # ubuntu: sudo apt-get install cmake sudo dnf install cmake git clone https://github.com/pmem/libpmemobj-cpp cd libpmemobj-cpp mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .. make sudo make install # # Also install libpmemkv for the key-value example. # cd git clone https://github.com/pmem/pmemkv cd pmemkv mkdir build cd build cmake .. -DCMAKE_INSTALL_PREFIX=/usr make sudo make install
