/*  -- LAPACK auxiliary routine (version 3.1) --   
       Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..   
       November 2006   

    Purpose   
    =======   

    DLANGE  returns the value of the one norm,  or the Frobenius norm, or   
    the  infinity norm,  or the  element of  largest absolute value  of a   
    real matrix A.   

    Description   
    ===========   

    DLANGE returns the value   

       DLANGE = ( max(abs(A(i,j))), NORM = 'M' or 'm'   
                (   
                ( norm1(A),         NORM = '1', 'O' or 'o'   
                (   
                ( normI(A),         NORM = 'I' or 'i'   
                (   
                ( normF(A),         NORM = 'F', 'f', 'E' or 'e'   

    where  norm1  denotes the  one norm of a matrix (maximum column sum),   
    normI  denotes the  infinity norm  of a matrix  (maximum row sum) and   
    normF  denotes the  Frobenius norm of a matrix (square root of sum of   
    squares).  Note that  max(abs(A(i,j)))  is not a consistent matrix norm.   

    Arguments   
    =========   

    NORM    (input) CHARACTER*1   
            Specifies the value to be returned in DLANGE as described   
            above.   

    M       (input) INTEGER   
            The number of rows of the matrix A.  M >= 0.  When M = 0,   
            DLANGE is set to zero.   

    N       (input) INTEGER   
            The number of columns of the matrix A.  N >= 0.  When N = 0,   
            DLANGE is set to zero.   

    A       (input) DOUBLE PRECISION array, dimension (LDA,N)   
            The m by n matrix A.   

    LDA     (input) INTEGER   
            The leading dimension of the array A.  LDA >= max(M,1).   

    WORK    (workspace) DOUBLE PRECISION array, dimension (MAX(1,LWORK)),   
            where LWORK >= M when NORM = 'I'; otherwise, WORK is not   
            referenced.

/**
    Purpose
    -------
    DPOTRF computes the Cholesky factorization of a real symmetric
    positive definite matrix dA.

    The factorization has the form
       dA = U**H * U,   if UPLO = MagmaUpper, or
       dA = L  * L**H,  if UPLO = MagmaLower,
    where U is an upper triangular matrix and L is lower triangular.

    This is the block version of the algorithm, calling Level 3 BLAS.

    Arguments
    ---------
    @param[in]
    ngpu    INTEGER
            Number of GPUs to use. ngpu > 0.

    @param[in]
    uplo    magma_uplo_t
      -     = MagmaUpper:  Upper triangle of dA is stored;
      -     = MagmaLower:  Lower triangle of dA is stored.

    @param[in]
    n       INTEGER
            The order of the matrix dA.  N >= 0.

    @param[in,out]
    d_lA    DOUBLE PRECISION array of pointers on the GPU, dimension (ngpu)
            On entry, the symmetric matrix dA distributed over GPUs
            (dl_A[d] points to the local matrix on the d-th GPU).
            It is distributed in 1D block column or row cyclic (with the
            block size of nb) if UPLO = MagmaUpper or MagmaLower, respectively.
            If UPLO = MagmaUpper, the leading N-by-N upper triangular
            part of dA contains the upper triangular part of the matrix dA,
            and the strictly lower triangular part of dA is not referenced.
            If UPLO = MagmaLower, the leading N-by-N lower triangular part
            of dA contains the lower triangular part of the matrix dA, and
            the strictly upper triangular part of dA is not referenced.
    \n
            On exit, if INFO = 0, the factor U or L from the Cholesky
            factorization dA = U**H * U or dA = L * L**H.

    @param[in]
    ldda     INTEGER
            The leading dimension of the array dA.  LDDA >= max(1,N).
            To benefit from coalescent memory accesses LDDA must be
            divisible by 16.

    @param[out]
    info    INTEGER
      -     = 0:  successful exit
      -     < 0:  if INFO = -i, the i-th argument had an illegal value
      -     > 0:  if INFO = i, the leading minor of order i is not
                  positive definite, and the factorization could not be
                  completed.
