Scylla BLAS

Implementation of (part of) BLAS specification that uses Scylla database to store matrices/vectors.

Algorithms are parallel - main library divides task into subtasks, and delegates them to workers - all communication is done trough Scylla.

Building

Clone the project

  https://github.com/scylla-zpp-blas/linear-algebra

Go to the project directory

  cd linear-algebra

Update submodules

  git submodule update --init --recursive

Create build directory and cd into it

  mkdir build

Build project

  cmake ..
  make

This will build in Release mode. If you want to build in Debug mode add -DCMAKE_BUILD_TYPE=Debug flag to cmake (before ..).

To change log level, use -DSCYLLA_BLAS_LOGLEVEL=<level> where <level> is one of TRACE, DEBUG, INFO, WARN, ERROR, CRITICAL.

Tests are by default built only in Debug mode. You can override that behaviour with -DBUILD_TESTS=ON/OFF. Example programs are always built by default. You can disable that with -DBUILD_EXAMPLES=ON/OFF.

Files produced by build:

• .so files - the library to link against.
• scylla_blas_worker
• (only in Debug) tests/scylla_blas_tests

Usage

To use library, you need to add include to your inlude directories, and link against .so library that was built.

Before using, database must be initialized: ./scylla_blas_worker --init -H scylla_address.

To run a worker: ./scylla_blas_worker --worker -H scylla_address
