High-Performance Computing in R

  • to
  • Level 7

    4807 Rockside Road, Cleveland, OH (map)

    41.399265 -81.657417

  • Get off at Rockside from 77 and go West. We are close to the highway on the North side. Parking at the building is free and there is always plenty of space. The meeting will take place in the basement.
  • The meeting will take place on the 7th floor in a room provided by Level7.


    We are trying a new meeting location in Independence to accommodate those from the east, and those from the west.  However, space is limited so there will be a hard cap at 35 people allowed to RSVP, so please only RSVP if you are sure you can attend.  If all the seats are taken, we will set up a GoToMeeting so you can view from your home.  Please email me before July 9 if you will be using this option.  Meeting details below:


    R is an incredibly rich and powerful language for exploratory data analysis and scientific computing. But, often mistakenly, R is not considered a good language for high-performance computing. In fact the language provides a remarkably comprehensive set of tools for high-performance computation.
    We'll discuss tips and tricks for writing R code for high-performance computation, including:

    - Using fast low-level numeric libraries
    - Writing vectorized code
    - Working with data larger than memory
    - Parallel processing with 'parallel,' 'foreach,' and others
    - Using the right algorithms

    We'll focus on practical computation and show examples of fast large-scale principal components and generalized linear models among others. Feel free to come with questions about performance!

    Bryan Lewis has worked with R for many years and is the author of several R packages including irlba, rredis, doRedis, websockets, bigalgebra, scidb, and others. He is the chief data scientist at Paradigm4 in Waltham, MA and has a Ph.D. in applied mathematics.

    I was going to come, but given the crazy weather I think I need to stay closer to home tonight. Sorry!!

    One point of clarification - The Meeting Will Be In Our Offices on the 7th Floor. We had originally planned for the basement, but there is no wifi available down there. Come to the 7th floor, our offices are left out of the elevator.

    Does anyone have insight into traffic at that time, coming from Mayfield Village area? Don't want to be late because of being naive!

      480W is particularly bad that time of day, I would leave early

    I'm very sorry to miss this talk. Bryan is an expert on HPC and R; you don't want to miss this!
