CSYTRF_nopiv_gpu computes the LDLt factorization of a complex symmetric matrix A.
The factorization has the form A = U^T * D * U, if UPLO = MagmaUpper, or A = L * D * L^T, if UPLO = MagmaLower, where U is an upper triangular matrix, L is lower triangular, and D is a diagonal matrix.
This is the block version of the algorithm, calling Level 3 BLAS.
[in]  uplo  magma_uplo_t

[in]  n  INTEGER The order of the matrix A. N >= 0. 
[in,out]  dA  COMPLEX array on the GPU, dimension (LDDA,N) On entry, the symmetric matrix A. If UPLO = MagmaUpper, the leading NbyN upper triangular part of A contains the upper triangular part of the matrix A, and the strictly lower triangular part of A is not referenced. If UPLO = MagmaLower, the leading NbyN lower triangular part of A contains the lower triangular part of the matrix A, and the strictly upper triangular part of A is not referenced. On exit, if INFO = 0, the factor U or L from the Cholesky factorization A = U^H D U or A = L D L^H. Higher performance is achieved if A is in pinned memory, e.g. allocated using cudaMallocHost. 
[in]  ldda  INTEGER The leading dimension of the array A. LDDA >= max(1,N). 
[out]  info  INTEGER
