Chameleon is a framework written in C which provides routines to
|
|
solve dense general systems of linear equations, symmetric positive
|
|
definite systems of linear equations and linear least squares
|
|
problems, using LU, Cholesky, QR and LQ factorizations. Real
|
|
arithmetic and complex arithmetic are supported in both single
|
|
precision and double precision.
|
|
|
|
Chameleon is based on the PLASMA source code but is not limited
|
|
to shared-memory environment and can exploit multiple GPUs.
|
|
Chameleon is interfaced in a generic way with StarPU, PaRSEC,
|
|
QUARK, OpenMP runtime systems. This feature allows to analyze in
|
|
a unified framework how sequential task-based algorithms behave
|
|
regarding different runtime systems implementations. Using Chameleon
|
|
with StarPU or PaRSEC runtime systems allows to exploit GPUs through
|
|
kernels provided by cuBLAS and clusters of interconnected nodes with
|
|
distributed memory (using MPI).
|
|
|
|
|
|
The default scheduler is set to OpenMP, if you want to use the StarPU
|
|
you should set the environment variable STARPU=yes and install StarPU.
|
|
|
|
For enabling MPI set the environment variable MPI=yes, this require
|
|
a MPI implementation (openmpi or mpich).
