CodeChef SnackDown 2015 - Code Your Heart Out
To honor the very long service of our old checkers, we would like to share a little more of their background story with you. The SPOJ website is developed and maintained by Sphere Research Labs. The "sphere" is cited in described in many sources as the perfect three-dimensional shape - the model of beauty and excellence. The naming convention for our computing clusters is also based on spatial geometry: our servers' names include "Cubes", "Cones", "Pyramids", and "Prisms".
SPOJ started out in 2004 with a bunch of vintage 266MHz machines named "Cones". These were very soon completely replaced by the freshly withdrawn "Pyramid" cluster. The single computing unit for "Pyramids" was the Intel Pentium III 733 MHz, and submissions at SPOJ were allowed to use up to 256MB of memory. The slowness of Pyramids by today's standards was often seen by problem setters as an advantage: it was possible to distinguish fast algorithms from slow ones without creating enormous datasets. The new "Cube" cluster consists of modern and fast Intel Pentium G860 CPU's and your submissions are run with a 1536 MB memory limit.
The chart below shows the number of pieces of code executed annually on the "Pyramid" cluster, between 2004 and last year. That's exactly 10074843 submissions in total. Since 2012, you can also see how many submissions were executed using the "Cube" cluster. The two clusters were almost equally loaded in 2014.
The last Pyramid submission was executed on 2015-03-02 at 10:51:35. We turned off the Pyramid cluster on the same day at noon GMT+1.
We hope that when we share the next chart with you at some point in the next 10 years, the submission rate will still be increasing at least as quickly as in the last decade!
