GPU, Lubuntu, ML - bloody roots

I have presented myself with a CUDA-compatible VGA card for Christmas (Asus GT730) so that I can check out Theano and GPU computing in general. No matter the appetite, having the appropriate amount of business to deal with, I was conveniently procrastinating the installation. Could be good intuition :)

I tried reinstalling it a few times, until I found that some RAM-drive for whatever reason needs to be purged:

sudo update-initramfs -u

Running this at the beginning & also the end of the previously attempted installation steps, I believe it's "there" now, although it was missing a couple of things.

When running Octave, it was still complaining for not having a video driver in place

Xlib:  extension "GLX" missing on display ":0".

A page said that adding a couple of lines to the code (it was the Coursera Machine Learning course's ex3.m) can remedy the situation ... and in fact I only needed to insert the line

graphics_toolkit gnuplot

right after the initial clean-up:

%% Initialization
clear ; close all; clc

and that solved this one of my problems. Or I could at least see that initial plot.


Some of the Cuda examples are broken now, though. Not sure why (perhaps just a missing path), but when running

MonteCarloMultiGPU

I'm getting this:

error while loading shared libraries: libcurand.so.7.5: cannot open shared object file: No such file or directory

... thank you so much, laters, then ...
