Re: Magma on Windows and Visual Studio

Hi Philip, yes I did run test programs (although not all of the bundled tests) successfully with the dll. At the moment I require just a visual studio and CLAPACK + CBLAS. I'm still looking into compiling magma as a .dll as well (remember I just compiled magmablas). Sadly, I have very little time to...

Re: Magma on Windows and Visual Studio

Hi Philip, I found the same that linking magmablas (the nvcc compiled portion) statically does not work with the MinGW gcc compiler due to mvscrt dependencies which are introduced during the compilation with the cl.exe based nvcc. I think we can't do anything about this dependency gcc just ain't sup...

Re: Magma on Windows and Visual Studio

Hi, I can confirm that Magma builds on Windows. I did build magmablas as a .dll using VS2008. Magma itself was build using Mingw-w64 (32bit sezero). I will try to build both as a .dll within the next days. Would it be possible to decorate all functions considered as API with a macro like MAGMA_DLL_A...

Re: MAGMA without FORTRAN

I don't think this is possible since part of MAGMA itself seems to be derived from the Lapack/Blas itself which is written in Fortran.
Therefore, I think a Fortran Compiler is required in any case.

Re: MAGMA on Windows

What is the state of MAGMA on windows? I compiled it using MinGW, but it the examples crash at cuInit.
Also compilation is a painsome process since nvcc defaults to cl.exe (Visual C) on Windows.
I think for Windows it might be more suitable to provide precompiled libraries.

Thx,
Frank

testing examples: why is ldda a multiple of 32?

I noticed that for some routines like zgemm and zgesv the LDA dimensions are set to be multiples of 32. Is this preferred for some reason?

double precision routines on compute capability <1.3 devices

Hi, MAGMA really seems great. However, I noticed that on devices with compute capability <1.3 (no double precision, afaik) the behavior is as misleading as supplied tests are. A lot of tests, including the zgemm and dgemm tests pass without any warning, as they compare only MAGMA against CudaBLAS re...
