Barcelona OpenMP Task Suite is a collection of applications that allow to test OpenMP tasking implementations and compare its behaviour under certain circumstances: task tiedness, throttle and cut-offs mechanisms, single/multiple task generators, etc.

        SUITE DESCRIPTION

=================

The objective of the suite is to provide a collection of applications that allow to test

OpenMP tasking implementations. Most of the kernels come from existing ones from other

projects. Each of them comes with different implementations that allow to test different

possibilities of the OpenMP task model (task tiedness, cut-offs, single/multiple generators,

etc). It currently comes with the following kernels:

   + Alignment: Aligns sequences of proteins.

   + FFT: Computes a Fast Fourier Transformation.

   + Floorplan: Computes the optimal placement of cells in a floorplan.

   + Health: Simulates a country health system.

   + NQueens: Finds solutions of the N Queens problem.

   + Sort: Uses a mixture of sorting algorithms to sort a vector.

   + SparseLU: Computes the LU factorization of a sparse matrix.

   + Strassen: Computes a matrix multiply with Strassen's method.

FILE DESCRIPTION

================

The package directory is organized as follows:

   + ./bin: target directory when compiling the benchmarks (generated by `./configure').

   + ./common: source code for common objects.

   + ./config: config directory, assist the compilation phase.

   + ./inputs: input files for some of the benchmarks (when needed).

   + ./omp-tasks: source code for the OpenMP Task versions.

   + ./run: scripts for running the benchmarks.

   + ./serial: source code for the serial versions.

   + ./templates: template directory.

SUITE COMPILATION

=================

Briefly, the shell commands `./configure` and  `make` should configure and build this package.

The `./configure` shell script attempts to guess correct values for various system-dependent

variables used during compilation (compiler and OpenMP specific flags). The shell script

examines the compilers installed in the system and let the user choose among them.  It uses

those values to create a `make.config` in `./config` directory which will be used during

the suite compilation.

If you need to change compilers, linkers or compilation options you can change manually the

file `./config/make.config`.

OTHER ISSUES TO TAKE INTO ACCOUNT

=================================

Some benchmarks are coded following a recursive model which makes an intensive use of stack

frames. It is usually needed to increase default stack sizes when working with high recursion

levels. Main stack size can be increased using `ulimit -s` linux command. Thread stacks are

usually controlled through runtime specific environment variable (e.g. Intel C Compiler uses

`KMP_STACKSIZE=value` for this purpose).
