At its core, R is a very carefully curated high-level interface to low-level numerical libraries. True to this principle, R packages have greatly expanded the scope and number of these interfaces over the years, among them interfaces to a large number of distributed and parallel computing tools. I believe the idiosyncrasies of most HPC technologies represent the major road block to their adoption in any language or system. HPC technologies are often difficult to set up, use, and manage. They often rely on frequently changing and complex software library dependencies, and sometimes highly specific library versions. Managing all this boils down to spending more time on system administration, and less time on research. How do we make things easier?

However, as R integrates with an increasing number of external libraries and frameworks like cuDNN, r singularity, Spark, and others, the ability to reproduce the software environment that R runs in is becoming both more important and more complex.

A container is a collection of the software requirements to run an application. Importantly, containers are defined and generated from a simple text recipe that can be easily communicated and versioned. Containers leverage modern operating system capabilities for virtualizing process and name spaces in a high-performance, low-overhead way.

Assume that our four host computers are listed in a comma-separated list by the environment variable HOSTS, for instance by. Top Submissions all year month week day hour. Both services "speak the same language" that language is called 'ActivityPub' , so you can view and interact with Mastodon content from Lemmy, and vice versa. R file in the container working directory and running: singularity run tensorflow. Apologies in advance! In particular, this algorithm process the chunked VCF data out of core — alternative versions of the program pin sparse matrix chunks in memory on each computer and avoid intermediate file system use. Please note that I work on this only as a hobby, so I may not be able to implement feature requests and bug fixes in a timely manner. Full-sized example Finally, compute the whole genome principal components across all chromosomes and all 2, people in the Genomes project with: Remove small example files if they exist rm -f chr To give you an idea of performance, I ran this example on four Amazon EC2 rxlarge instances. Load Data. Choosing which Lemmy site to sign up to is a bit like choosing your email provider - e. R file in the container working directory and running:. Full-genome variant Principal Components The previous example illustrated a complex tool chain, but only running on a single computer. The matrix entries are one if a particular variant occurs in the person, or a zero otherwise. The example is very general, requiring an arbitrary number of VCF data files as input and running on any number of computers.

Our informatics group has several big memory 1TB computing nodes that allow us to run interactive jobs.

HPC technologies are often difficult to set up, use, and manage. Importantly, containers are defined and generated from a simple text recipe that can be easily communicated and versioned. Posts Per Day. The minimalist philosophy of Singularity makes it easy to install and run on everything from laptops to supercomputers, promoting the ability to quickly test containers before using them across large systems. Click on the link icon next to the subreddit's name to go directly to the subreddit. Singularity encapsulates the program logic and the external library dependency chain MPI, etc. The example downloads whole genome data files in VCF 4. The following examples assume that Singularity is installed on your system. And Singularity runs without a server at all, eliminating possible server security exploits. I encourage using the test section judiciously to confirm that the container will work as intended. Data collection may not work properly please direct complaints to reddit admins. Note 4 : It's worth mentioning that Lemmy is young - the Lemmy devs are working hard to quickly improve the software, and server admins have been constantly moving to larger machines to support the influx of new users, so please be patient with bugs and issues.
