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