Got compute? future.apply 1.0.0 - Apply Function to Elements in Parallel using Futures - is on CRAN. With this milestone release, all* base R apply functions now have corresponding futurized implementations. This makes it easier than ever before to parallelize your existing apply(), lapply(), mapply(), … code - just prepend future_ to an apply call that takes a long time to complete. That’s it! The default is sequential processing but by using plan(multiprocess) it’ll run in parallel.

As promised - though a bit delayed - below are links to my slides and the video of my talk on Future: Parallel & Distributed Processing in R for Everyone that I presented last month at the eRum 2018 conference in Budapest, Hungary (May 14-16, 2018). The conference was very well organized (thank you everyone involved) with a great lineup of several brilliant workshop sessions, talks, and poster presentations (thanks all).

A new version of the future.BatchJobs package has been released and is available on CRAN. With a single change of settings, it allows you to switch from running an analysis sequentially on a local machine to running it in parallel on a compute cluster. Our different futures can easily be resolved on high-performance compute clusters. Requirements The future.BatchJobs package implements the Future API, as defined by the future package, on top of the API provided by the BatchJobs package.

A new version of the future package has been released and is available on CRAN. With futures, it is easy to write R code once, which later the user can choose to parallelize using whatever resources s/he has available, e.g. a local machine, a set of local notebooks, a set of remote machines, or a high-end compute cluster. The future provides comfortable and friendly long-distance interactions. The new version, future 1.

Unless you count DSC 2003 in Vienna, last week’s useR conference at Stanford was my very first time at useR. It was a great event, it was awesome to meet our lovely and vibrant R community in real life, which we otherwise only get know from online interactions, and of course it was very nice to meet old friends and make new ones. The future is promising. At the end of the second day, I presented A Future for R (18 min talk; slides below) on how you can use the future package for asynchronous (parallel and distributed) processing using a single unified API regardless of what backend you have available, e.
