Description PetaMem R&D 2016-05-15 07:38:06 UTC 
torch-3.1 is obsolete and will most likely not work with any current version of CUDA.

If we take the cuda release history: https://developer.nvidia.com/cuda-toolkit-archive

And the availability date of torch-3.1 (2009) see e.g. https://www.rpmfind.net/linux/RPM/fedora/23/x86_64/t/torch-3.1-12.fc23.x86_64.html

Then torch-3.1 is in the very best compatible with cuda 2.3

Here's the thing: The current torch7 does support CUDA 6.5 and cuDNN 4. However, current version is CUDA 7.5 and cuDNN 5

While I managed to get it work under Gentoo, torch seems to have a hard time to keep up with the CUDA release pace.

The CUDA API changed significantly with CUDA 4, today torch is basically a lua-based API and not a C++ based API anymore.

I do not think it makes sense whatsoever to keep torch-3.1 except you expect to run a modern gentoo on historic (2009) CUDA setups.

Installing torch-3.1 and trying to compile any of the examples there yields

# make
Makefile:15: /data/soft/Makefile_options_Linux: No such file or directory
make: *** No rule to make target '/data/soft/Makefile_options_Linux'.  Stop.

# locate Makefile_options
#

or

# equery f sci-libs/torch | grep -i make
/usr/share/doc/torch-3.1/examples/decoder/Makefile.bz2
/usr/share/doc/torch-3.1/examples/discriminatives/Makefile.bz2
/usr/share/doc/torch-3.1/examples/generatives/Makefile.bz2
/usr/share/doc/torch-3.1/examples/speech/Makefile.bz2
/usr/share/doc/torch-3.1/html/mxMakeH.html
/usr/share/doc/torch-3.1/html/mxMakeHQ.html



I think it's dead and pointless.

Reproducible: Always

    profiles/package.mask: mask sci-libs/torch for removal, bug #583068

# David Seifert <soap@gentoo.org> (15 May 2016)
# Masked for removal. Deprecated, relies on ancient CUDA APIs,
# does not build with current CUDA releases. See bug #583068.
