Re: [julia-users] IBM Power port

I have uploaded Julia-0.5 on Power8 binaries here. These are built with the latest openblas (that passes all julia tests) and hence there is no need to use ATLAS. https://drive.google.com/open?id=0B0rXlkvSbIfhVWpZb2hqclBIVms Would be great if people can try this out. -viral > On Aug 19,

Re: [julia-users] IBM Power port

I am getting successful builds on the OSU Power8 machine. Once openblas has a new release, I suspect we can provide pre-packaged power8 binaries. I am building on CentOS 7 and this is what lscpu says: Architecture: ppc64le Byte Order:Little Endian CPU(s):

Re: [julia-users] IBM Power port

It is hard to say what is happening there. Trying it out. OpenBLAS develop branch is now passing on Power and hence Atlas should no longer be required. Note that you need the latest (3.10.4?) ATLAS, but in any case, this should not affect the build. -viral > On Aug 18, 2016, at 7:03 PM,

[julia-users] Changing juliabox font size on iOS

Hey all, I'd like to use Juliabox to do some real-time demos from an iPad Pro running over the HDMI connection. One the issues is that the font size in juliabox is too small in the context. The zooming on the iPad scales things like a picture, but doesn't reflow the layout in light of the

Hi Evan, A minimal reproducing example isn't necessary; it's great to have any example, and yours is pretty minimal already. It's always worth opening an issue for these things. The one critical bit I'd like is to know exactly what you ran so I can just copy and paste something and see the

[julia-users] Re: When can the broadcast dot (in 0.5) be used?

My understanding (which can easily be wrong!) is that this stems from https://github.com/JuliaLang/julia/issues/16966. Namely that size("b") throws a method error, whereas your size(2) gives a null tuple (). So in general broadcast (which is what the .() is sugar for) requires that the element

Greetings everyone, So we all know that Symbol is not a bits type. And AFAIK only bits types can be used as type parameter. However, I can still use Symbol as a type parameter in type signatures. Is there a special property of Symbol that allows it to do so? Or is there something I'm missing
