[julia-users] Why Ubuntu 16.04 version runs only on one CPU?

Prior to running Ubuntu 16.04, I get Julia from the PPA, and run it simply like: > julia Then when I run julia code, "top" shows CPU usage of Julia as something like 200% (I have two cores). Now on 16.04, julia only runs upto 100% of CPU. The version of julia is said to maintained by "Ubuntu

julia> round(Int, typemin(Float64)) ERROR: InexactError() in round at ./float.jl:181 Should this be handled this way? Or is it better to make round(Int, typemin(Float64)) to be typemin(Int)? Also, why is typemin(Float64) -Inf but typemin(Int) -9223372036854775808? Can typemin(Int) be made -Inf

Say a function is named FuncA. I hope to get this name into a string like "FuncA". Is there a way to do that?

I have some const defined in various files in the following way: [code]const AConst=1[/code] Everytime after I modify something in the files (constants remain unchanged) and include a file on Julia's REPL, I always get a bunch warnings about redefining constants. Repeating the process many time

[julia-users] Is Ubuntu's PPA needed for installing Julia?

So the PPA has not been maintained for many months. I tried to download a Linux generic version of Julia and it appears to work well on my Xubuntu 15.10 64bits. So my question is do we really need the PPA to install Julia?

that works for dependencies that need to be in the search path. In the mean time, to get it to work, you can install xz (e.g., `brew install xz`, if you use homebrew outside of Julia). Cheers, Kevin On Sat, Jun 13, 2015 at 5:19 PM, K leo cnbiz...@gmail.com wrote: In another message I
