By MikeMirzayanov, 4 weeks ago, In English,

Hello.

Unfortunately, the Educational Codeforces Round 91 round will be unrated and, actually, it was completely ruined. I don’t understand what happened yet. At some point in time, all systems began to work unstably and actually stopped working. So far I have no understanding what happened. You may have to change the schedule for future rounds. Sorry. We have such a black stripe. Very upset and demotivated.

Mike.

    I think there should be an option of giving / sponsoring money for the rounds throughout the year, like we had on the 10th anniversary, so that they can upgrade their servers or do the needful. Also, these days there will be huge participation due to lockdown, so even if they manage to get some temporary fix for the next few rounds, there is a chance that systems will fail in future as well so they need money to maintain the servers.

    CF can also start up their own merchandise, since it is a huge community and it is growing very fast, I'm sure there are a lot of people who would like to wear those tees and hoodies and coffee mugs while giving the contest. xD.

    There can be also perks top-50 donors of the whole year will get a t-shirt of their name or something like that.

      Open-sourcing Codeforces can also be a good idea? Open source organisations raise a lot of money and also the quality of their code is great!

I don't know how exactly servers work. But I am sure that many people (including me) would be more than happy to come forward and fund money for codeforces to use stable servers.

      100k goes to regular rounds, at 400 dollars a round, hosting 1 round per week costs them 22000 dollars.

      I don't expect Mike to raise 100k each year though, and I'm sure there is some money coming in from sponsorships from companies for edu and global rounds.

      However, Mike and Una and other members on the cf team need paychecks too, so 100k in the long run for such a huge nonprofit website/platform is honestly really small :(

    As someone who works on system reliability (not on CF of course), I think the problems we see look more like a software or process issue than something to do with bad hardware. That's much harder to fix than "just throw money at it" :(

    I hope Mike will figure out some way to update the platform in a safe manner, or make tests that actually catch these types of issues. It's not the end of the world if something breaks and a contest is unrated. But when it happens time and time again, this becomes disheartening.

      I would like to politely disagree with you, setting problems in a month and hoping everyone would enjoy their contest on the D-day, only to find that a month's work is wasted just because of some unexpected issues in the servers. Try putting yourself in their shoes.

      Making quality problems in a month is still a tough task and take a lot of time... You need to find interesting problems that contestants will enjoy, create strong tests... Btw, if it's "so easy" why don't you write problems ?

      I've started creating problems in polygon in March. From then, I have prepared 6 (maybe 7) problems in the div2 A-D range that are not inherently bad.

      I can't imagine how hard it is to make good problems and strong pretests in that short timeframe, especially since div2 E-F are very difficult to make.

I think adding one or more servers may reduce the spike in the load. Considering the fact that participation has increased in recent rounds, the problems are bound to happen. There is no need for demotivation. Cheers.

we can somehow make the entire codeforce infrastructure as open source and ask more participant to contribute, optimize, improve its overall quality and performance.

While enjoying the high quality contest, it is also important to maintain the infrastructure itself together.

    As much as I enjoy div4 rounds as an unofficial participant, I feel that unrated testing rounds are better, since they reuse simple problems and require less effort than a div4 round.

    The purpose of a testing round is not to be a contest, and the other way round.

Thanks for your work investigating this problem. As a first suggestion on rescheduling, I'd propose that Monogon's next round should be rescheduled until after a Div. 2 or Div. 3 round is successfully completed. Div. 1 problemsets are sufficiently rare and hard to prepare that until the Codeforces system has been thoroughly tested by an actual round, it seems better to risk wasting a Div. 2/Div. 3 round than a Div. 1 contest.

So, after yesterday problem with queue made round unrated I thought it might be a good idea to reschedule round until everything will be fixed. I am really upset that a lot of problems got spoiled because of server problems. Hoping things like this won't happen later.

Also, codeforces has gathered nearly 100000$ recently, I believe its more than enough to get good servers....

Regardless of the server issue along with long queues , last couple of rounds had given us a great problem set which i think most of us enjoyed solving. In my opinion the hardwork of the problem setters were totally worth in providing such great problems. Hopefully it gets continued with strong server and we all could get more enthusiastic for CF rounds.

I have an Idea to implement P2P Online Judge. In volunteer contestants PC should have G++, Java, Python3 major compilers. A client process will recieve annonymous contestant code with test case, compile, run, check and finally give response back to the server. I think this will be a revolutionary change for CF platform.

    So (possibly with the help of reverse engineering) it will be possible to access the submissions, the test cases and the correct answers for them? (there are also more languages than just C++, Java and Python 3 on Codeforces)

      It may be possible by sophisticated decryption algorithm and computing power. But for most of us it is hard nut to crack. And 95% of the contestants use these 3 languages ( C++, Java & Python). If P2P OJ can be done, 95% load of the server can be reduced. Rest 5% of the load can easily be handled by the CF server utilizing compilers/interpreters of remaining languages.

        I think you can intercept the submissions by simply replacing the compiler with a script that first saves the submission somewhere and then invokes the actual compiler. That seems almost impossible to prevent (to me).
