MAGMA Forum

Hi shriniwas852, welcome.

Thank you for your effort.

A simple working example CMakeLists.txt based on the one you're using, would be more helpful.

Kind regards,

The above compiles and runs only in Release mode.. Anyone can think of a reason for that? (which then I'll try to verify) EDIT: Dear Mike, or Hartwig, are you able to compile example_sparse.cpp with debug symbols? (-g flag in linux correct?) and statically? (-static flag in linux I believe) (https:/...

Oh! I saw that in the example_sparse example, but I didn't understand it at the time due to missing this "All iterative solvers and eigensolvers included in the MAGMA-sparse package work on the device. Hence, it is required to send the respective data structures to the device for solving, and back t...

// Inputs: // Eigen::SparseMatrix<double> A // Eigen::VectorXd b magma_dopts opts; // Choose a solver, preconditioner, etc. - see documentation for options. opts.solver_par.solver = Magma_PIDRMERGE; opts.solver_par.restart = 8; opts.solver_par.maxiter = 1000; opts.solver_par.rtol = 1e-10; opts.solv...

Finally compiling and running. Here is the CMakeLists.txt that did it add_executable(magma-test example_sparse.cpp) find_package( CUDA ) set( MKLROOT "D:/Program Files (x86)/IntelSWTools/parallel_studio_xe_2019.0.045/compilers_and_libraries_2019/windows/mkl" ) set( LAPACK_LIBRARIES "D:/Program Files...

Hi jlangworthy,

Would you kindly attach here (or post a link to) the end result CMakeLists.txt you used? Both to compile MAGMA, and then to compile your own code using MAGMA later?

Thank you

Ok, I just determined this is reproducible in my machine: - I just deleted MAGMA folder completely - and did a complete rebuild, *just* in Debug mode, as described in https://stackoverflow.com/questions/53132124/list-of-causes-for-lnk2038-msvs2017-magma - and the same behavior was observed I'm now a...
