DO YOU FEEL LUCKY?

They're checkpointed. But the file could have been corrupted when your PC crashed.
Today my computer with GTX 1060 3GB turned off by itself while crunching a DYFL task for the first time.
Could a software crash cause this? Or is a hardware problem?
This computer crunches 24/7 and completed successfully GFN-17, 18, 19, 20 and 21 tasks some days ago.
When I start BOINC client now, I get 'no project URL in task state file' message. Indeed boinc_task_state.xml is corrupted. BOINC shows that this task is at 97% and GPU uses about 25% of load, probably it's doing nothing. Task was at ~50% before shutdown.
A file named genefer.log appeared. It says: "Errors occurred for all available transform implementations".
Can I only abort it or is there some way to recover it?
P.S. Meanwhile I'm testing GPU with Amicable Numbers project that uses a lot of CPU/GPU memory.

Well you need a bit of luck here and I had zero for TDP 2020.
I was pumping out plenty of GFN 16 with my RTX2080 and 65-70 second run times.
Nothing, not even a double check.
I feel you, bro. I found 1 Proth prime (PPSE, luckily first) after ~29k tests over the years.
~15k GFN16 and nothing too.

Miraculously, I was able to discover prime on the mountain stage.
And it was a megaprime, the best outcome. Congratz!
Nice to see the jerseys go to four different persons.
Nice! :)

...and you can just throw money at this project, it leaves anyone out who doesn't have the money or want to spend thousands on 50+ computers and GPUs spending hundreds a month on electricity...
The real wastefullness in challenges is to run multithreading when it's not the most efficent solution.

If your host is very fast and you are 80% first, you will observe that your first rate tends to 50% though.

I don't understand your premise. Even in your example, the next guy in line wins. There is no harm to anyone. If the first guy returns first, he wins. If the second guy is the first to return because the first guy fails, the second guy wins. And so on.[
As to getting original task vs resends, we have already been told by the admin here that it is random. I think you are claiming grievance about being issued resends vs new tasks. No way to avoid that, regardless of the amounts of aborts of previous tasks.
Yeah, number of resends is higher than it should be because someone is aborting a bunch of tasks. Fair or not? Are those aborts justified?
Race is killed.

Is it not good to be second, when the first are abandoned? In other words, what is the harm? I am obviously missing the point of the complaint. Why the anger?
WUs are sent to 2 users. When he aborts it, you are the third and you almost always do double check.
Maybe you will be 50% first on average cause of this. If your machine can get more than 50% first (not my case), it's not nice.

I found 1 user who downloaded tons of SR5. I don't know if it's good news.
He aborted the most work yesterday and he downloaded 885 SR5 tasks on 1 single host today. I guess he is going to abort hundreds of tasks again. Is this pratice tolerated?
