Ta-dah!

We present the long-awaited new, fresh, and crispy design of SPOJ! It's taken us a while to get here since 2004, but hey, it looks good - doesn't it? There's now a new feature for tagging and grading problems. We are also working to make SPOJ as mobile-friendly as possible. Stay tuned, because there are many more surprises to come!

Goodbye Pyramid

During the last six months, we have been gradually migrating our "checkers" (servers which execute submissions) from old to new machines. The procedure required some care since the new machines have significantly greater processing power. The main difficulty was adjusting the time limits for problems: in general, the new machines seemed to be more "tolerant" of slow solutions than the old ones. Over the 10 years of existence of SPOJ, our great community has produced over 13.5 million submissions (10 million of which on the old checkers) and we didn't want to rejudge all of them. So, we designed an algorithm for recalculating submission running times by interpolation. Data for reliable interpolation came from a real rejudge of a representative sample of 5% of the submissions, i.e., 511,000 submissions have been rejudged over the past six months. At the end, we changed the time limits of test cases keeping them in relation to running times of solutions.

Despite our best efforts, we cannot guarantee that all recalculated times are completely accurate. If you are concerned about your score, we encourage you to resubmit your solution. If you are an author of the problem, please verify the time limits of test cases - especially when your problem was designed to distinguish fast and slow algorithms!

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 These were very soon completely replaced by the freshly withdrawn "Pyramid" cluster.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.

Submissions by year chart

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!

Banning cheaters

We have intensified banning cheaters (users who copy codes from the internet and submit them here). Soon all of them from "Cheaters" thread on forum will be banned. If you are a cheater you can avoid ban by disqualifying all your cheating submissions until we get to you. After mentioned thread all users from top100 (and then top256) will be x-rayed.
