I do not know an answer, but you may want to use the amazon cluster generator (cfncluster). It is under constant development, unlike starcluster. It may be easier. https://github.com/awslabs/cfncluster On Friday, September 9, 2016 at 7:21:33 PM UTC-5, Alexandros Fakos wrote: > > Hi, > > I

In my experience it is helpful to have a Fortran version to compare speeds against when learning Julia. This would be easy w.r.t. your problem. It is easy to right functional Julia code that is very slow, but looks okay. The best way for me was to have have a basis of comparison. On Monday,

I ran into this problem before with punctuation. https://github.com/JuliaLang/julia/commit/b418a03529a9afec07c5aa032a9124b03cef912e#diff-91ec6806d45dd62d07012f6a018b151f Maybe this should be addressed again. On Wednesday, September 23, 2015 at 5:32:57 PM UTC-5, Alex Copeland wrote: > > > > Hi,

Thanks for the detailed answers. They were very helpful. This sort of thing where you have data -> calculated abstraction -> recover data, is so frequent that having a generic way of building this sort of tool will be hugely valuable. Recovering data by text is useful, but there are times

+100 This has loads of possibilities. Great work. I am guessing it would be possible, but how difficult would it be to read in a jpg, and explore it in a similar fashion. On Monday, September 14, 2015 at 10:15:04 AM UTC-5, Tim Holy wrote: > > I'm pleased to announce the availability of the

I was thinking the second option. It would be great to be able to hotwire the gadfly part and read in plots with pointers to previous rendered images. I do not understand how difficult it would be to mimic gadfly output from other sources. How tricky was that part of this work? I would be

This looks very impressive. I assume it works with multi-dimensional functions f(x,y,z)? It also looks very fast. What are the limitations to it? Where would you still use analytic derivatives?

This is great progress. Similarly, is there a way for benchmarking on different versions of the code? Automating this will be very helpful.

I implemented an program in Fortran and Julia for time comparison when learning the language. This was very helpful to find problems in how I was learning julia. Maybe I did not read carefully enough, but I would compile the fortran with the intel compilers (not MKL) instead of gcc as

What you are doing makes sense. Starting from multiple starting points is important. I am curious why you just don't just run 20 different 1-processor jobs instead of bothering with the parallelism? On Saturday, July 26, 2014 11:22:07 AM UTC-5, Iain Dunning wrote: The idea is to call the

Julia is not as performant with anonymous functions, and list comprehension. The compiler has a harder time with the optimization step. This is not a surprise and is known to the language designers. This is not a surprise. On Saturday, July 5, 2014 8:01:46 PM UTC-5,
