optimize_gemv¶
Performs internal optimizations for oneapi::mkl::sparse::gemv by analyzing the matrix structure.
Description and Assumptions
The oneapi::mkl::sparse::optimize_gemv routine analyzes matrix structure and performs optimizations. Optimized data is then stored in the handle.
optimize_gemv (Buffer version)¶
Syntax
namespace oneapi::mkl::sparse {
void optimize_gemv (sycl::queue &queue,
oneapi::mkl::transpose transpose_val,
oneapi::mkl::sparse::matrix_handle_t handle);
}
Input Parameters
- queue
Specifies the SYCL command queue which will be used for SYCL kernels execution.
- transpose_val
Specifies operation
op()on input matrix. The possible options are described in transpose enum class.- handle
Handle to object containing sparse matrix and other internal data. Created using the oneapi::mkl::sparse::set_csr_data routine.
Throws
This routine shall throw the following exceptions if the associated condition is detected. An implementation may throw additional implementation-specific exception(s) in case of error conditions not covered here.
optimize_gemv (USM version)¶
Syntax
namespace oneapi::mkl::sparse {
sycl::event optimize_gemv (sycl::queue &queue,
oneapi::mkl::transpose transpose_val,
oneapi::mkl::sparse::matrix_handle_t handle,
std::vector<sycl::event> &dependencies);
}
Input Parameters
- queue
Specifies the SYCL command queue which will be used for SYCL kernels execution.
- transpose_val
Specifies operation
op()on input matrix. The possible options are described in transpose enum class.- handle
Handle to object containing sparse matrix and other internal data. Created using the oneapi::mkl::sparse::set_csr_data routine.
- dependencies
List of events that oneapi::mkl::sparse::optimize_gemv routine depends on.
Throws
This routine shall throw the following exceptions if the associated condition is detected. An implementation may throw additional implementation-specific exception(s) in case of error conditions not covered here.
Return Values
Output event that can be waited upon or added as a dependency for the completion of optimize_gemv routine.
