Eigen::gpu::SparseLLT< Scalar_, UpLo_ > Class Template Reference

#include <contrib/Eigen/src/GPU/GpuSparseLLT.h>

Detailed Description

template<typename Scalar_, int UpLo_ = Lower>
class Eigen::gpu::SparseLLT< Scalar_, UpLo_ >

GPU sparse Cholesky factorization (LL^T for real, LL^H for complex).

Wraps cuDSS with CUDSS_MTYPE_SPD (real) or CUDSS_MTYPE_HPD (complex). Accepts ColMajor SparseMatrix (CSC), reinterpreted as CSR with swapped triangle view for zero-copy upload.

Template Parameters

Scalar_	float, double, complex<float>, or complex<double>
UpLo_	Lower (default) or Upper — which triangle of A is stored

Constructor & Destructor Documentation

SparseLLT() [1/2]

template<typename Scalar_, int UpLo_ = Lower>

Eigen::gpu::SparseLLT< Scalar_, UpLo_ >::SparseLLT ( Context & ctx )

inlineexplicit

Borrow ctx's stream so solves chain with other work on the same Context. ctx must outlive this object.

SparseLLT() [2/2]

template<typename Scalar_, int UpLo_ = Lower>

template<typename InputType>

Eigen::gpu::SparseLLT< Scalar_, UpLo_ >::SparseLLT ( Context & ctx, const SparseMatrixBase< InputType > & A )

inline

Borrow ctx's stream and factor A immediately.
