Re: MAGMA on windows or linux

Hello,

I'm surprised you are using f2c, this was the Fortran / C limking library for f77, if all your code is compiled with gfortran, -lgfortran should be enough.
Or with the option -ff2c to compile f2c compliant code according to the man.

Re: Error making libmorse_quark

Hello, The quark branch is still work in progress, so it may not compile, and it won't use GPUs. If you want to use multi-gpus branch, you should use StarPU scheduler. A new version of MAGMA is in development to introduce a cmake compilation process, that will ease the compilation of the this librar...

Re: issue about using magma with PGI fortran

Hi, I'm sorry but I have no idea how to do that. The only thing I know is that if you use PGI, you shouldn't use the MAGMA Fortran interface because PGI compiler can handle the pointer on GPU as any other arrays. So, I think the idea is more to look at what we started for PGI interface but that we d...

Re: Magma Installation: CLAPACK problem

Hi,

Thansk for rising this. f2c is a very old library used by f77 when you mix C and Fortran. gfortran doesn't use it anymore. It uses -lgfortran instead and is automatically added normally.
So just remove the -lf2c from the LIB variable.

Re: How to install MAGAMA

Hi, concerning PLASMA use the PLASMA installer you'll find on the link I gave you last time. And once you have untar the archive on your machine, just run : ./setup.py --prefix=directory_where_you_want_to_install This will give you an unoptimized version of PLASMA using all the reference libraries f...

Re: runtime of testing subroutine

When it's possible, overlap is done mainly by using look ahead techniques.

Re: How to install MAGAMA

The easiest way to install blas and lapack if you are not interrested by the performances is to use the plasma installer with the configuration by default. (http://icl.cs.utk.edu/plasma/software/index.html)
Otherwise you can install MKl or ACML which will provide you BLAS and LAPACK.

Re: magma installation using intel compiler Version 12.0.2

Hi,

For gfortran: just remove the .mod file or do a "make cleanall" before to recompile with gfortran. You probably still have the .mod generated by ifort.
For ifort: add the option -fpp after ifort in FORT to force the precompilation of the files.

Re: How to install MAGAMA

Hi David, To try MAGMA, take one of the make.inc close to your configuration and adapt it to your specific case by giving your compiler, the path to your libraries, the GPU family you are targeting. And then just type make. If you have any problems, with the compilation, just reply to this post with...

Re: MKL vs MAGMA

I don't know especially for this serie but usually yes, except that the multiplication factor will change from one function to another.
