Update to R on Grid 2.5

November 16, 2018

Thanks again for being an early adopter of the new compute grid. As we’re about to open officially on Monday, we would like to take this opportunity to update the central R / RStudio installation for a number of reasons. We would do this work early in the day on Monday, and it would upgrade R to 3.5.1, from 3.4.2. (Note that this update would require an update/reinstall of any R packages that had been compiled.)

Thanks,

RCS Staff

Compute Grid 2.5 Update

October 25, 2018
In our previous newsletter we announced our new computing environment, Grid 2.5, with an anticipated release of this fall. The new compute environment provides:
  • Improved compute capacity through more hardware and better using of existing hardware
  • Fewer restrictions on compute capacity while preventing CPU spillover
  • Newer OS and software versions, and improved usability
  • More software titles, including GitKraken (for version control) and Spyder, a Python IDE
  • Better command-line submission scripts, to improve...

New Tip from the RCS Data Team

October 25, 2018

The EXPLAIN statement is a very useful tool in SQL databases to help users better understand what's going on in queries and where to apply tweaks. For example, the output of EXPLAIN can help you decide where to add indexes and can quickly remedy slow queries by telling you the join type, the possible indexes to choose vs. the index actually chosen, the estimate of rows to be examined, etc.

How do you use EXPLAIN?

Simply put the keyword EXPLAIN in front of the query to be analyzed. EXPLAIN can be used in front of a query beginning with...
