Re: Magma 1.5.0 Compiler requirements on Ubuntu

I have installed gcc/g++/gfortran 4.5 and set this in the makefile. CUDA is still accessing the default compiler (4.6) and stopping. Is there a define for CUDA to tell it to look at the other compiler?

Re: Magma 1.5.0 Compiler requirements on Ubuntu

My current CUDA version is 4.1 and that may be the problem. Please advise me what to do. Update CUDA?

Magma 1.5.0 Compiler requirements on Ubuntu

I am returning to use Magma after some time away and have downloaded 1.5.0. When I copy my makefile which works for 1.3.0 and run make I get the following error message: #error -- unsupported GNU version! gcc 4.6 and up are not supported! This implies that gcc 4.6 and higher versions are not support...

Re: Magma 1.40 benchmarks - GeForce GTX TITAN; Linux

I suggest to people using GotoBLAS to move to OpenBLAS instead which is its successor and still being developed. This avoids some problems with the last release of GotoBLAS

http://www.openblas.net/

I am a contented user.

Re: NaN errors with dpotrf and dpotrf_gpu

It is interesting that the last posting was for work on a Tesla i.e. not the cheap versions of the cards.

Re: GMRES on magma

Is there any news on this? I could not see anything in the 1.4.0 release notes.

Re: Help please with choice of forums

Thank you very much. It would be very useful to have a diagram which illustrated the interdependencies of the different projects.

I have not found anything on that.

Re: Multicore and MultiGPU use of MAGMA

I think this is a good example of the sort of question which crosses between the different projects and does not seem to get answered here at the moment.

Where can this question be asked?

Thank you

John
