Re: Sparse Direct Solver

You mean function magma_dgesv() is ILU? Can I use it as direct solver for sparse matrix?

Sparse Direct Solver

I would like to know which routine is for sparse LU direct solver? I would like to know whether the LU solve under Linear Systems in the documentation can be used for solving sparse matrices? Thank you!

Incorporate my code into MAGMA

I would like to know how difficult if I want to incorporate my code into this library? I tried to use the ILU preconditioner with BiCGStab and I noticed the run time is even slower than the pure BiCGStab. If I would like to developing my own ILU, how hard it would be for me to put my code into your ...

Timing the code

I am using sparse-iter module and I would like to timing the whole process solving the Ax=b which means I also needs to timing for example the time data transfer from CPU to GPU. I would like to know whether I can use something like real_Double_t tempo1 = magma_sync_wtime( queue ); /* code needs to ...
