Real world comparison of Monte Carlo Gibbs simulations for HFT between C, C++, Java, Python, R, Scala, and Groovy?

Real world comparison of Monte Carlo Gibbs simulations for HFT between C, C++, Java, Python, R, Scala, and Groovy? Surprised on the winner?

This is the closest real world comparison I could find. I think what is written is dead on! It seems Python with PyPy is a good choice but has little library support. Java is nearly as good as C so I have no point in relearning new languages like Groovy, Python, or Scala. They are not that popular in the banking world anyways so for career move that could be a time waster. There was a mention of using R for prototyping and extending through Java or C++ with R packages like Rcpp or RCppGSL. It looks impressive.

The R with Rcpp and RcppGSL looks like promising too.

I might go this route so we shall but posting definitely help out. Java with R is another very good option with Rcaller.

Twitter’s Scalding library is a Scala package around Cascading Java API to create Hadoop jobs

If you have read the paper published by Google’s Jeffrey Dean and Sanjay Ghemawat (MapReduce: Simplied Data Processing on Large Clusters), they revealed that their work was inspired by the concept of functional languages: “Our abstraction is…

I think dean wampler is doing something at strange loop on scalding.

F# becomes first popular functional language to hit top 20 according to Tiobe. Sorry not Scala, Clojure, Haskell or Erlang

F# becomes first popular functional language to hit top 20 according to Tiobe. Sorry  not  Scala, Clojure, Haskell or Erlang

Most people thought that hot functional languages such as Scala (#66), Clojure (#107), Haskell (#35) or Erlang (#48) would be the ones that would be the first to compete seriously with the mother of all functional languages Lisp. But it appears to be Microsoft language F#. The recent rise in popularity of F# comes as no suprise. Apart from being a nicely designed language, F# is available in the latest version of Microsoft’s Visual Studio (2010).
