Sorry, but really don't know what is going on. Today I had two sessions
of julia each running a program (single processing), then the machine
froze with no mouse and keyboard. This type of thing happened a few
times in the past though not every time I run 2 julia sessions. I don't
know how to determine the real cause, but suspect it has to do with
julia. Hasn't anyone had similar experiences?
I am running Xubuntu 14.04.
$ julia
