Hello,
I need the final residual value and number of iterations needed at the end of the solver run.
I read that "final_res" and "numiter" are the related variables or functions, I assume from a monitoring class.
How can I retrieve these values?

Dear Hartwig, originally I worked with the following solvers which, in combination, were really fast to solve my physics problem but only 2D on the CPU, now I have to move to 3D with GPU support I think because the 3D case will have about 30.000.000 cells: For symmetric matrices: PCG + IC preconditi...

compiled magma library has no functionality
Hello, after many issues with a MKL based installation on Ubuntu 16.04, I tried to install magma with openblas support based on the make.inc example for openblas. Findings: 1: make shared Compilation takes place 2: make test Something happens but as there's no "feedback" concerning a result or succe...

Where can I find the linear solver documentation?
Hello,
I am looking for a documentation describes the setup of the MAGMA linear solvers BiCG, BiCGSTAB, CG, IDR ... and the parameters for their configuration in my application code. I assume I am overlooking something but I couldn't find it.

MKL shared libraries not "found" in the accepted lication
Hello, even so the shared and static libraries are not properly installed (see previous thread), I identified another issue of the shared library when I tried to make the examples. Apparently, the path to the Intel MKL is wrong. The magma shared library looks for the Intel MKL shared libraries in /u...

make install issues
Hello, I tried to install the shared and static library one after another and applied accidently 'sudo make install prefix=/usr/local/magma' a second time' applying "sudo" a second time causes an error and the installation fails. The problem is, the error stays, I can't repeat the installation. erro...

Solved: Installation fails: /usr/bin/ld: cannot find -lgfort
just for the record, the problem was caused by a mismatch of gcc/g++ <> gfortran compiler versions, updating gfortran is the fix

Re: Efficient computation (solve) of Ax = b when A is symme
Dear Hartwig,
based on your insights, I assume it's only a wrapper that hides an efficient copy process (lower<>upper) so I'll try the same - we'll see whether there's a benefit.
