int PLASMA_sgesv_Tile ( PLASMA_desc *  A,
PLASMA_desc *  L,
int *  IPIV,
PLASMA_desc *  B 
)

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

Parameters:
[in,out] A On entry, the N-by-N coefficient matrix A. On exit, the tile L and U factors from the factorization (not equivalent to LAPACK).
[in,out] L On exit, auxiliary factorization data, related to the tile L factor, necessary to solve the system of equations.
[out] IPIV On exit, the pivot indices that define the permutations (not equivalent to LAPACK).
[in,out] B On 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_SUCCESS successful exit
>0 if 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.
