Re: Magma in Windows with ILP64

Hello Mark thank you very much for following up with the matter. From your data, it appears indeed that the extra performance granted by multithreaded MKL (versus seq. MKL) is substantial for moderate matrix sizes and becomes relatively smaller for large matrices. I am using my own test program (the...

Re: Magma in Windows with ILP64

Hello, In order to be able to specify Pascal for the build, I have added at the suitable places in CMakeLists.txt the following additions: ................................. if ( ${GPU_TARGET} MATCHES Pascal ) set( GPU_TARGET "${GPU_TARGET} sm61" ) endif() ................................. if ( ${GPU...

Re: trying to build magma-2.1.0 on Windows

Hello Casca I have just read your post from May 14, sorry I missed it for that long. You can find in the "Magma in Windows with ILP64" topic that I have opened since then a detailed description of my way of building magma.lib and magma-sparse.lib in Windows with ILP64 and MKL sequential (and of my c...

Re: Magma in Windows with ILP64

Hi I have done further experiments with my build of Magma in Windows with ILP64 and sequential MKL. I called magma_dgesv for 20000, 30000, 40000, 50000, 60000, 70000, 80000, 90000, 100000, 110000, 120000 and I repeated this series five times. For 20000, 30000, 70000, 80000, 90000, 100000, 110000, 12...

Re: Magma in Windows with ILP64

Hello I would be delighted if my experiments could help you smash a bug or two! By the way, currently, it is possible to specify in the GUI of Cmake the architectures Fermi, Kepler and Maxwell only. Would it be possible to have Pascal as well? (from my experience, it should not make any noticeable d...

Re: Magma in Windows with ILP64

Hello, By "terminates prematurely" I simply mean that it finishes obviously way too soon, for example faster than a successful run with a smaller size. It seems to work fine for some time and then suddenly terminates. It then returns info=0, which seems normal, but when I print the solution values i...

Re: Magma in Windows with ILP64

Hello again, the situation has improved a bit: I fixed a bug in my test code of magma_dgesv with ILP64 and it now works fine until m=30000, just like with LP64. However, beyond that, things are uncertain: usually, a run terminates prematurely with the solution vector filled with -nan(ind)'s. But if ...

Magma in Windows with ILP64

Hello, I have been able to build Magma in Windows 10 with Visual Studio 2015 and MKL (for both Blas and Lapack). I entered into the GUI of CMAKE the following: set LAPACK_LIBRARIES to: C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017.2.187\windows\mkl\lib\intel64_win\mkl_intel_lp64_d...

It's just about keeping hope... :-) Right now, I am able to complete partially the build with Visual Studio 2010: 570>------ Skipped Build: Project: INSTALL, Configuration: Release x64 ------ 570>Project not selected to build for this solution configuration ======...

Re: trying to build magma-2.1.0 on Windows

Hello I am also trying to build magma in windows, without success so far. I wonder, would it be possible for me to obtain the magma.lib and magma-sparse.lib files that you have managed to create? They are too big to pass as email attachments, but maybe through ftp ? I am sure other people would be i...
