[julia-users] Best compile and benchmark for haswell and broadwell architectures?

is there a standard benchmark command to confirm we're getting the "fastest" julia? I did look around for help in the forms and via google, and found bits and pieces. (e.g. JULIA_CPU_TARGET, for instance...). Just wondering what the latest recommendations and experiences are! Thanks! David Gleich

Ahah! That explains it. Is there a better way to create floating point literals that avoid this? David On Wednesday, September 14, 2016 at 9:26:42 AM UTC-4, Steven G. Johnson wrote: > > > > On Wednesday, September 14, 2016 at 9:18:11 AM UTC-4, David Gleich wrote: >> >&

Thanks for that! I figured someone else must have run into this but my googling and searching efforts were in vain! Is the time-frame for the next release imminent? I was hoping to use juliabox in a class I'm starting next week, but this issue could be problematic for many of those students to

[julia-users] Juliabox cannot start after Pkg.add (unlink error in read-only file system)

I'm trying to use juliabox.org and running into issues that make it unusable for me. Essentially, after I do a Pkg.add operation, the kernel can no longer connect. It seems like it's trying to execute an unlink operation on the read-only portion of the juliabox file system. Da
