Long Wu's

[dividedbymyself]

Hi,
I'm currently crunching some very long RNA Wu's. One of them seems to be validated already for some of the wingmen. At the moment I've got about 33 hours left to go. Is is useful to continue this one or should I better abort not to loose more time than than I already did?

Also there's no checkpointing. This doesn't matter for Wu's of a couple of hours max, but when they take days it's a different story. Wouldn't it possible to implement checkpointing in the near future?

Thanks for any advice,
Bart

Concerning you request for checkpointing:
You are not the first, who requested it. We are working on a solution for the checkpointing, but unfortunately we are using algorithms, which have been designed for high performance clusters. Therefore there was no need for implementing checkpointing.

During the BOINC Workshop we had some nice discussions about using a method with virtual machines. There are some really nice approaches, we could use.

But honestly, our main problem is a huge lack of man power to finally do the coding and development. The methods, algorithms and source code is there. It just have to be put together.

Cheers,
Torbjoern

Hey,

since the WU is already validated, you can abort it on your host. As Torbjörn said, checkpointing is one of our great issues which we try to solve. As a temporary solution for the missing checkpoints, I'd suggest using standby and hibernation to save your progress. I do that on my machines and it works. A nice side-effect is that boottime is faster ;)

I just realized, that this thread has been sneaked into the wrong board. It's dealing with RNA World and not Yoyo@home.

Thanks guys, it's aborted. And about the checkpointing, we'll have to wait then. Hopefully there will not be too many of these large Wu's.
And about the sneaking in the wrong forum, I just posted in the first "number crunching" board could find I'll be more careful next time.
