A special acknowledgement to Yves Gallot and the other team scientists for the recent enhancements introduced in genefer, although the official announcement will come after post-challenge feedback ?
Merci Yves!

To get slightly more points and a few ranks, participants get a lot of tasks, then abort the less advantageous.

I completely agree. The sentence above is false. It is pointless to select among tasks. The design is fair.
You brightly demonstrated that there is no advantage to abort tasks.

@Skillz: You're the only first!
As first, do you care of being first to return tasks because your probability to find a prime is optimal ?
What's is your overall first percentage ? Has it changed since the beginning of the challenge ?
Note that in french "premier" means first but also prime!


I don't know what my overall is. I've got a bunch of 3090s in the race and all of them are 90%+ first rate. I've also got some really slow 1080 and 1070 cards that are around 50%.

Quite impressive! Glad to doublecheck/second a few of your firsts.

When the work unit is new, typically two tasks are generated with names ending in _0 and _1. Often the two tasks are sent out at about the same instance of time (it is random if _1 or _0 goes out first). Let us say the careless user X mentioned gets one of them, and some random user A gets the other one. Now A has an advantage in becoming 1st, because X is not going to complete his tasks correctly, so A can easily get first. Even if A has a slow computer, they can get first.

This here should clear it up then.

If I'm not mistaken bcavnaugh is assuming that the task ending in _1 was the second task of that work unit to be sent. If you are saying that it's random that _1 or _0 is sent first then no user will be able to have an advantage by aborting all tasks ending in _1.

The advantage being returning the task first because they received the task first. When being the first to return a task is the goal.

However, for the purpose of winning the competition it doesn't matter as long as the task was downloaded at the start of the challenge or somewhere in between the start and end. Then returned before the end of the challenge. Additionally, that returned task must be a valid task.

#29 is fine, #125 too, in the metaverse.

Thank you for your explanations, JeppeSN. It's a lot more clearer.

But, if you're C and get an aborted task ending by _2 or _3 ?
An what should happen to X ?
There is no first if the task was aborted ? It happens more often than one would believe.

Definitively, the algorithm and criteria to be first should be detailed.
First to return ? Minimum run time ? Date received ?

To be first or not to be first ...

This could be avoided by an amount of point per task fixed in advance for the whole challenge.
