recommended GPUs (GTX580-3GB and a GT640-2GB) ??

dear Magma creators/developers I'd like to ask it you maybe have your favourite or recommended GPU(s)? Or maybe you have conducted some benchmarks? Reason I wonder is that I have here a GTX580-3GB and a GT640-2GB, the former is supposedly faster according to what one can gather form Internet sources...

Re: magma R package/library fails to build

I realise I missed out path to magma libs, but how do I get hold of magmablas?
changelog reads "...Merge libmagmablas into libmagma to eliminate circular dependencies....."

is it rather R magma package that needs some work, updates?
would there be a workaround?

regards

magma R package/library fails to build

dear all I'm trying to install magma R package but build fails, I'm hoping you can help. my MAGMA is built with gcc and ACML 5.3.1, build seems successful, I ran some tests from testing and all seem good (by the way, on AMD platforms it seems to be worth all the efforts to build with ACML, for CPU t...

Re: error compling shared library in version 1.4.0

thank you mgates3
can confirm I missed one -fPIC, now I have

NVOPTS = -O3 -DADD_ -Xcompiler "-fno-strict-aliasing -fPIC"

and it all builds, however, I was hoping I could use magma R package but builds fails, I should put it into a separate post
thanks

magma 1.4 + acml + cbals = need a bit of clarification

dear experts I'm trying to help my fellow scientist to glue together all the different bits & bobs, myself am not a programmer and this is why I don't quite get it. It is simple for you I believe - since ACML (5.3.1) advertises itself as full implementation of BLAS and LAPACK - why do I still need c...
