Ø I had a similar error a few days ago. It is probably somewhere in the build log. Without any patching, CUDA refuses to install if your gcc is too new (for CUDA 7.5 it can't be newer than gcc 4.8). For cuda and gcc versions in one place see here<https://urldefense.proofpoint.com/v2/url?u=http-3A__stackoverflow.com_a_6622751_2554989&d=DwMGaQ&c=UE1eNsedaKncO0Yl_u8bfw&r=RMJdCm7m5fiPWhajwKUnEW5yn4eK2YdUWW-MLVShghg&m=iuOtSZ1a81IOeF-ZEBzrqlwm6JBmfcGIF-AGjXM8fKo&s=ygihs42gXltryS6CVWO0XlF7LY_e2JAqZnLxR6aToUU&e=>.
I just wanted to add my thoughts, it seems like Benjamin was correct, according to the link I was able to build CUDA 8.0 with GCC 5.2.0. Another link from CUDA: https://devtalk.nvidia.com/default/topic/949770/cuda-8-0rc-supporting-gcc6-/ I think the initial release fosscuda toolchain could be with GCC-5.3.0, CUDA-8.0.44. This could be the latest release for time being, it would also make sense to build fosscuda toolchain with CUDA 7.5 since most HPC sites are probably still running on kepler cards and haven’t moved to the Pascal.

The bioinfo people tend to use it for ease of support as much of the software is built with it already and absolute best performance isn't always more important than getting the compilation done in less time.

We're however doing mostly dummy -> GCCcore -> iccifort -> iompi -> iomkl -> iomklc and dummy -> GCCcore -> gcc -> gompi -> gomkl -> gomklc Maxime On 17-03-02 18:38, Vanzo, Davide wrote: Maxime, your point it totally legitimate. My approach is less about philosophy and more about practicality. We picked the foss toolchain instead of the goolf toolchain because of its more collaborative nature and scheduled release. The problem is that if we now start using a goolfc toolchain, we could not get the benefit of reusing most of the software built with foss since we build with minimal toolchains. Hence I proposed of starting a fosscuda toolchain that is aligned with the foss release.

Isn't the whole point of FOSS to be free and open source ? CUDA is not open source. Won't die-hard fan of FOSS object to having CUDA in a FOSS toolchain ? I personally don't really care, I just want the best performance for my users (which is why we don't go with FOSS in the first place, since MKL gives better performances than OpenBLAS). I just thought I'ld raise the question. -- --------------------------------- Maxime Boissonneault Analyste de calcul - Calcul Québec, Université Laval Président - Comité de coordination du soutien à la recherche de Calcul Québec Team lead - Research Support National Team, Compute Canada Instructeur Software Carpentry Ph.
