PLASMA - Parallel Linear Algebra for Scalable Multi-core Architectures
int PLASMA_sgesv_Tile ( PLASMA_desc A,
int *  IPIV,
PLASMA_desc B 
)

PLASMA_sgesv_Tile - Solves a system of linear equations using the tile LU factorization. Tile equivalent of PLASMA_sgesv(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.

Parameters
[in,out]AOn entry, the N-by-N coefficient matrix A. On exit, the tile L and U factors from the factorization.
[out]IPIVOn exit, the pivot indices that define the permutations.
[in,out]BOn entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X.
Returns
Return values
PLASMA_SUCCESSsuccessful exit
>0if i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the solution could not be computed.
