Main concepts:
- Slack, as in Stale Synchronous Parallel (bounded assynchrony)
- GASPI, an API enabling fast one-sided communication with RDMA
This project uses the CMake meta-build system, version 3.10 or above.
Critical dependencies: GPI-2, C compiler with C99 standard support Optional dependencies: ASan & UBSan compiler support, googletest, C++ compiler
Please note that the final linking step with GPI-2 should be done with your application build step; to compile this library, having the GASPI header files is enough.
If you choose to compile and install Lapser as a shared library (the default option),
remember to run ldconfig after installing the library, to set up the appropriate
bindings in your system linker.
If you want to run the tests, you'll need the GPI-2 library installed
in a suitable location (this is, find-able by the linker and
with the gaspi_run command present in PATH), and also
a local copy of GoogleTest,
which is used as a unit testing framework.
The location of the GoogleTest library must be indicated in
the GTEST_CMAKE_PATH CMake variable (either by using the option
-DGTEST_CMAKE_PATH on the cmake command or by using
make edit_cache afterwards).
Additionally, you should create a machinefile named hosts.txt
at the project source directory, to be used in the gaspi_run command.
After that, you can run the tests from your build directory using:
make check
- Use a sparser datastructure to map the meta_items and items to their segment location (right now it uses an array of pointers indexed by the item id)
- Make push less eager to send new versions (it is not considering slack when sending)
- Better logging and time measurements
