class hip.hipsparse.bsrsv2Info#

Bases: Pointer

Python wrapper for cdef class chipsparse.bsrsv2Info.

If this type is initialized via its __init__ method, it allocates a member of the underlying C type and destroys it again if the wrapper type is deallocated.

This type also serves as adapter when appearing as argument type in a function signature. In this case, the type can further be initialized from a number of Python objects:

None:

This will set the self._ptr attribute to NULL.
int:

Interprets the integer value as pointer address and writes it to self._ptr. No ownership is transferred.
ctypes.c_void_p:

Takes the pointer address pyobj.value and writes it to self._ptr. No ownership is transferred.
object that implements the CUDA Array Interface protocol:

Takes the integer-valued pointer address, i.e. the first entry of the data tuple from pyobj’s member __cuda_array_interface__ and writes it to self._ptr.
object that implements the Python buffer protocol:

If the object represents a simple contiguous array, writes the Py_buffer associated with pyobj to self._py_buffer, sets the self._py_buffer_acquired flag to True, and writes self._py_buffer.buf to the data pointer self._ptr.
hip._util.types.Pointer:

Takes the pointer address pyobj._ptr and writes it to self._ptr. No ownership is transferred.

Type checks are performed in the above order.

C Attributes:

_ptr (C type void *, protected):: Stores a pointer to the data of the original Python object.
_is_ptr_owner (C type bint, protected):: If this wrapper is the owner of the underlying data.

hip.hipsparse.hipsparseXcsrsv2_zeroPivot(handle, info, position)#

Sparse triangular solve using CSR storage format

hipsparseXcsrsv2_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT , if either a structural or numerical zero has been found during hipsparseScsrsv2_solve(), hipsparseDcsrsv2_solve(), hipsparseCcsrsv2_solve() or hipsparseZcsrsv2_solve() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the CSR matrix.

position can be in host or device memory. If no zero pivot has been found, position is set to -1 and HIPSPARSE_STATUS_SUCCESS is returned instead.

Note:

hipsparseXcsrsv2_zeroPivot is a blocking function. It might influence performance negatively.

hipsparseXbsrsv2_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT , if either a structural or numerical zero has been found during hipsparseXbsrsv2_analysis() or hipsparseXbsrsv2_solve() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the BSR matrix.

position can be in host or device memory. If no zero pivot has been found, position is set to -1 and HIPSPARSE_STATUS_SUCCESS is returned instead.

hipsparseXbsrsv2_zeroPivot is a blocking function. It might influence performance negatively.

hipsparseXbsrsm2_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT , if either a structural or numerical zero has been found during hipsparseXbsrsm2_analysis() or hipsparseXbsrsm2_solve() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the BSR matrix.

Sparse triangular system solve using BSR storage format

hipsparseXbsrsm2_solve solves a sparse triangular linear system of a sparse \(m \times m\) matrix, defined in BSR storage format, a dense solution matrix \(X\) and the right-hand side matrix \(B\) that is multiplied by \(\alpha\), such that

\[op(A) \cdot op(X) = \alpha \cdot op(B),\]

with

\[\begin{split}op(X) = \left\{ \begin{array}{ll} X, & \text{if trans_X == HIPSPARSE_OPERATION_NON_TRANSPOSE} \\ X^T, & \text{if trans_X == HIPSPARSE_OPERATION_TRANSPOSE} \\ X^H, & \text{if trans_X == HIPSPARSE_OPERATION_CONJUGATE_TRANSPOSE} \end{array} \right.\end{split}\]

Note:

The sparse BSR matrix has to be sorted.

Note:

Operation type of B and X must match, if \(op(B)=B, op(X)=X\).

Note:

This function is non blocking and executed asynchronously with respect to the host. It may return before the actual computation has finished.

Note:

Currently, only trans_A != HIPSPARSE_OPERATION_CONJUGATE_TRANSPOSE and trans_X != HIPSPARSE_OPERATION_CONJUGATE_TRANSPOSE is supported.

hip.hipsparse.hipsparseXbsrilu02_zeroPivot(handle, info, position)#

Incomplete LU factorization with 0 fill-ins and no pivoting using BSR storage format

hipsparseXbsrilu02_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT , if either a structural or numerical zero has been found during hipsparseXbsrilu02_analysis() or hipsparseXbsrilu02() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the BSR matrix.

position can be in host or device memory. If no zero pivot has been found, position is set to -1 and HIPSPARSE_STATUS_SUCCESS is returned instead.

Note:

If a zero pivot is found, position \(=j\) means that either the diagonal block \(A_{j,j}\) is missing (structural zero) or the diagonal block \(A_{j,j}\) is not invertible (numerical zero).

Note:

hipsparseXbsrilu02_zeroPivot is a blocking function. It might influence performance negatively.

hipsparseXcsrilu02_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT , if either a structural or numerical zero has been found during hipsparseXcsrilu02() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the CSR matrix.

position can be in host or device memory. If no zero pivot has been found, position is set to -1 and HIPSPARSE_STATUS_SUCCESS is returned instead.

Note:

hipsparseXcsrilu02_zeroPivot is a blocking function. It might influence performance negatively.

hip.hipsparse.hipsparseXbsric02_zeroPivot(handle, info, position)#

Incomplete Cholesky factorization with 0 fill-ins and no pivoting using BSR storage format

hipsparseXbsric02_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT , if either a structural or numerical zero has been found during hipsparseXbsric02_analysis() or hipsparseXbsric02() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the BSR matrix.

position can be in host or device memory. If no zero pivot has been found, position is set to -1 and HIPSPARSE_STATUS_SUCCESS is returned instead.

Note:

If a zero pivot is found, position=j means that either the diagonal block A(j,j) is missing (structural zero) or the diagonal block A(j,j) is not positive definite (numerical zero).

Note:

hipsparseXbsric02_zeroPivot is a blocking function. It might influence performance negatively.

hip.hipsparse.hipsparseSpruneDense2csr(handle, int m, int n, A, int lda, threshold, descr, csrVal, csrRowPtr, csrColInd, buffer)#

This function converts the matrix A in dense format into a sparse matrix in CSR format while pruning values that are less than the threshold. All the parameters are assumed to have been pre-allocated by the user.

The user first allocates csrRowPtr to have m+1 elements and then calls hipsparseXpruneDense2csrNnz() which fills in the csrRowPtr array and stores the number of elements that are larger than the pruning threshold in nnzTotalDevHostPtr. The user then allocates csrColInd and csrVal to have size nnzTotalDevHostPtr and completes the conversion by calling hipsparseXpruneDense2csr(). A temporary storage buffer is used by both hipsparseXpruneDense2csrNnz() and hipsparseXpruneDense2csr() and must be allocated by the user and whose size is determined by hipsparseXpruneDense2csr_bufferSizeExt(). The routine hipsparseXpruneDense2csr() is executed asynchronously with respect to the host and may return control to the application on the host before the entire result is ready.

hip.hipsparse.hipsparseSpruneDense2csrByPercentage_bufferSize(handle, int m, int n, A, int lda, float percentage, descr, csrVal, csrRowPtr, csrColInd, info, bufferSize)#

This function computes the size of the user allocated temporary storage buffer used when converting and pruning by percentage a dense matrix to a CSR matrix.

When converting and pruning a dense matrix A to a CSR matrix by percentage the following steps are performed. First the user calls hipsparseXpruneDense2csrByPercentage_bufferSize which determines the size of the temporary storage buffer. Once determined, this buffer must be allocated by the user. Next the user allocates the csr_row_ptr array to have m+1 elements and calls hipsparseXpruneDense2csrNnzByPercentage. Finally the user finishes the conversion by allocating the csr_col_ind and csr_val arrays (whos size is determined by the value at nnz_total_dev_host_ptr) and calling hipsparseXpruneDense2csrByPercentage.

The pruning by percentage works by first sorting the absolute values of the dense matrix A. We then determine a position in this sorted array by

\[pos = ceil(m*n*(percentage/100)) - 1 pos = min(pos, m*n-1) pos = max(pos, 0) threshold = sorted_A[pos]\]

Convert and prune sparse CSR matrix into a sparse CSR matrix

This function converts the sparse CSR matrix A into a sparse CSR matrix C by pruning values in A that are less than the threshold. All the parameters are assumed to have been pre-allocated by the user. The user first calls hipsparseXpruneCsr2csr_bufferSize() to determine the size of the buffer used by hipsparseXpruneCsr2csrNnz() and hipsparseXpruneCsr2csr() which the user then allocates. The user then allocates csr_row_ptr_C to have m+1 elements and then calls hipsparseXpruneCsr2csrNnz() which fills in the csr_row_ptr_C array stores then number of elements that are larger than the pruning threshold in nnz_total_dev_host_ptr. The user then calls hipsparseXpruneCsr2csr() to complete the conversion. It is executed asynchronously with respect to the host and may return control to the application on the host before the entire result is ready.

This function is used when converting a general BSR sparse matrix A to another general BSR sparse matrix C. Specifically, this function determines the number of non-zero blocks that will exist in C (stored using either a host or device pointer), and computes the row pointer array for C.

The routine does support asynchronous execution.

This function converts the general BSR sparse matrix A to another general BSR sparse matrix C.

The conversion uses three steps. First, the user calls hipsparseXgebsr2gebsr_bufferSize() to determine the size of the required temporary storage buffer. The user then allocates this buffer. Secondly, the user then allocates mb_C+1 integers for the row pointer array for C where mb_C=(m+row_block_dim_C-1)/row_block_dim_C. The user then calls hipsparseXgebsr2gebsrNnz() to fill in the row pointer array for C ( bsr_row_ptr_C ) and determine the number of non-zero blocks that will exist in C. Finally, the user allocates space for the colimn indices array of C to have nnzb_C elements and space for the values array of C to have nnzb_C*roc_block_dim_C*col_block_dim_C and then calls hipsparseXgebsr2gebsr() to complete the conversion.

hip.hipsparse.hipsparseScsrcolor(handle, int m, int nnz, descrA, csrValA, csrRowPtrA, csrColIndA, fractionToColor, ncolors, coloring, reordering, info)#

Coloring of the adjacency graph of the matrix \(A\) stored in the CSR format.

hipsparseXcsrcolor performs the coloring of the undirected graph represented by the (symmetric) sparsity pattern of the matrix \(A\) stored in CSR format. Graph coloring is a way of coloring the nodes of a graph such that no two adjacent nodes are of the same color. The fraction_to_color is a parameter to only color a given percentage of the graph nodes, the remaining uncolored nodes receive distinct new colors. The optional reordering array is a permutation array such that unknowns of the same color are grouped. The matrix \(A\) must be stored as a general matrix with a symmetric sparsity pattern, and if the matrix \(A\) is non-symmetric then the user is responsible to provide the symmetric part \(\frac{A+A^T}{2}\).

class hip.hipsparse.hipsparseSpGEMMDescr#

Bases: Pointer

Python wrapper for cdef class chipsparse.hipsparseSpGEMMDescr.

If this type is initialized via its __init__ method, it allocates a member of the underlying C type and destroys it again if the wrapper type is deallocated.

This type also serves as adapter when appearing as argument type in a function signature. In this case, the type can further be initialized from a number of Python objects:

None:

This will set the self._ptr attribute to NULL.
int:

Interprets the integer value as pointer address and writes it to self._ptr. No ownership is transferred.
ctypes.c_void_p:

Takes the pointer address pyobj.value and writes it to self._ptr. No ownership is transferred.
object that implements the CUDA Array Interface protocol:

Takes the integer-valued pointer address, i.e. the first entry of the data tuple from pyobj’s member __cuda_array_interface__ and writes it to self._ptr.
object that implements the Python buffer protocol:

If the object represents a simple contiguous array, writes the Py_buffer associated with pyobj to self._py_buffer, sets the self._py_buffer_acquired flag to True, and writes self._py_buffer.buf to the data pointer self._ptr.
hip._util.types.Pointer:

Takes the pointer address pyobj._ptr and writes it to self._ptr. No ownership is transferred.

Type checks are performed in the above order.

C Attributes:
