GASSER

An Autotunable System for Sliding-Window Non-Incremental Streaming Operators on GPU

Requirements

For building Gasser

  • gcc (>4.8)
  • cuda (>=8)
  • gsl (>=2)

Additionally Gasser depends from FastFlow (http://calvados.di.unipi.it/) and Dalaunay_linterp (http://rncarpio.github.io/delaunay_linterp/). These are header only libraries and are automatically downloaded during the building process but have additional requirements.

Required by Delaunay_linterp

Minimum requirements (see http://rncarpio.github.io/delaunay_linterp/ for the full requirements) are:

  • CGAL
  • GMP
  • Eigen

Building

Before building the programs, the user must manually edit the configuration file config/machine_config.h" detailing the characteristic of the execution platform. In particular, he/she must indicates:

  • SM, the number of streaming multiprocessor of the used GPU;
  • CORE_PER_SM, the numer of cuda core per streaming multiprocessor;
  • REPLICA, the number of the CPU replicas to use.

Please, be aware that all these parameters impacts performance. Read the instruction in the header file on how to choose them.

After this, to compile it is sufficient to run:

    $ make all

The produced binaries will be placed under the bin directory:

  • financial_cpu and financial_gpu represent respectively the cpu (implemented using FastFlow and Posix thread) and gpu (implemented with Gasser) version of the financial use case (query 1 in the paper);
  • soccer_cpu and soccer_gpu represent the cpu (FastFlow and Posix) and the gpu version (Gasser) of the soccer use case (query 2 in the paper).

Please note: the gpu versions are by default compiled with the raindrop heuristic. If you want to let the Manager tries exhaustively the different configuration, you can compile the programs with the BRUTE_FORCE preprocessor macrod defined. It can be enabled also by uncommenting line 46 in the file include/Win_GPU_Config.h

Known problems

When compiling you can receive an error regarding the delaunay_linter library:

delaunay_2_interp.h:39:23: fatal error: Eigen/Dense: No such file or directory

this could occur depending on your Linux distribution and installation path. A possible solution could be to edit the indicated file (under delaunay_linterp/src/delaunay_2_interp.h) and change the line 39 with the proper installation path of the Eigen library.
