Re: installation problems Magma 2.5

Have you tried the latest MAGMA 2.5.1 alpha 1? It should resolve many compiling issues from 2.5.

Re: dense eigensolvers?

For complex matrices: magma_[cz]heevd* uses divide-and-conquer magma_[cz]heevr* uses MRRR magma_[cz]heevx* uses QR iteration if MagmaRangeAll, or bisection if MagmaRangeV or MagmaRangeI. For real matrices, only divide-and-conquer is available: magma_[sd]syevd* BTW, MAGMA is at version 2.5, not 2.0. ...

Re: My computer slowed down after MAGMA, Any general tips to make my computer fast?

MAGMA won't affect your computers performance while it is not running. While it is running, it will use the processor and GPU, so other programs would run slow. This is expected.

Re: makefile question when adding a file to magmablas/ directory

As for setting up a new source file for use in CMake, you need to run `make generate` or `make CMake.src`. I'm not sure why CMake wouldn't find `control/magma_sauxiliary.cpp`. What version of MAGMA are you using? Or did you get MAGMA directly from the bitbucket repo? Possibly the `make generate` wou...

Re: makefile question when adding a file to magmablas/ directory

Also, you can compile using `make magmablas/dstddev_mean.o` (from the top magma directory) to compile a single file to see if it is working, without recompiling the entire library. E.g., mint ~/Documents/magma> make magmablas/dznrm2.o nvcc -m64 -O3 -DNDEBUG -DADD_ -Xcompiler "-fPIC -Wall -Wno-unused...

Re: makefile question when adding a file to magmablas/ directory

Currently, CMake won't see new files. They have to be added with `make` first, which will generate magma/CMake.src. MAGMA uses a precision generator (magma/tools/codegen.py) to generate all 4 precisions (s, d, c, z for single, double, complex-single, complex-double) from, usually, the complex-double...

Re: What is the best Linux distro for MAGMA 2.5

Shouldn’t matter, as long as they support CUDA. See Nvidia’s site.

Re: vl and vu DSYGVDX_2STAGE

If you want all the eigenvalues, use range = MagmaRangeAll, and you can ignore il, iu, vl, vu by passing in dummy values. If you want a subset of eigenvalues, use range = MagmaRangeV, and pass in vl, vu as the range of eigenvalues to find, e.g., to find all eigenvalues in half-open range (0.0, 1.0],...
