pgMark

pgMark is a domain- and query language-independent framework targeting highly tunable generation of both graph instances and graph query workloads based on user-defined schemas.

pgMark is based on gMark, for more details about gMark, please refer to our technical report: http://arxiv.org/abs/1511.08386**

pgMark is a version of gMark that supports property graphs, whereas gMark only supports edge-labelled graphs.

gMark was demonstrated in VLDB 2016. The gMark research paper was published in the TKDE journal.

How to compile

pgMark uses CMake. Using the commandline, first go to the pgMark directory, then:

ccmake .

Then press 'c' to configure and press 'g' to generate and exit. Then:

make

Note that by default pgMark assumes you have clang-tidy installed. If you do not have clang-tidy or do not want to install it, then you can remove the CXX_CLANG_TIDY target property from the CMakeLists.txt file. Based on if you use GCC or CLANG to compile the c++ code you can also pass CLANG_COMPILER_FLAGS or GCC_COMPILER_FLAGS to the target_compile_options command in the CMakeLists.txt file. You can find out what compiler make uses on your system by checking the CC environment variable.

If you use an IDE such as CLion it should automatically detect the CMakeLists.txt file and allow you to build. CLion also has the required binaries such as CMake and clang-tidy built-in.
