DENIS admins:

Can you please increase your deadlines? They currently are something like 12 hours, and then get prioritized by some clients because they are so short, and then my GPUs go idle because your tasks are run in deadline-risk mode.

How quickly do you need the results? Can you consider changing it to 5 days or greater? Maybe even 2 weeks? I'd like my GPUs to be able to do work again, while running your project.

Thanks,
Jacob

Hello Jacob,

First of all, thank you for your opinion, it's really important to us.

Second, in DENIS@home we not only want to use boinc to simulate cells, we are also collecting information about which parameters are best to generate the workunits for different types of simulations.

This is why we are going to change parameters like deadlines to improve the solve of the simulations. I can't say exactly when we are going to change it but if you want, we can post it in this forum.

We will be really thankful if you, as users, say to us what you can found more interesting to you in BOINC projects, we will be happy to listen to you, give you the most information that we can, and make best changes for simulations and users.

Thanks! Joel.

Absolutely, I'm glad to be here, and glad to be able to give feedback. :)
So far, my feedback is: Deadlines are too short, causing my GPUs and bitcoin miner coprocessors to go idle, because BOINC schedules your tasks as priority to run them in "deadline-risk mode / earliest-deadline-first mode".

If you don't really need them in 12 hours time, then I recommend something like 5 days or 2 weeks.

Side note: For me, they complete in 2 minutes. That's potentially a lot of overhead in transferring data back and forth, and in looking at the task results lists. If possible, it might be better to have the tasks take around 4-48 hours each, with checkpoints.

looks like you got that one, the run times have gone from 2 minutes to about 30
fyi...

Hello,

Yes we have different simulations, each block of 3125 simulations cost different times. We are searching about the best way to generate the work to the user and the best way to do it is using a real world scenario.

The first block costs about 2 minutes, the second one have to cost like 3x the time of the first block. Also it is penalized by the writing cost of the operations.

Regards, Joel.

Hi guys,

concrats on your new project!

I'm running boinc only part of the day, which means that the current 12-hour deadline will cause all not started/finished workunits to automatically time-out tomorrow morning. Maybe you could extend the deadline to 5 to 7 days or so. Thanks!

Kind regards,

Yes please extend the deadlines. We all typically run quite a few projects, short deadlines create havoc with the other projects we run.

Also some indication of work unit availability would be greatly appreciated. Your current batch is used up.

Let's keep this thread on-topic.

Please increase the deadlines :)
Otherwise, those of us with GPUs and coprocessors might have to detach :(

I aborted a bunch of Wu's, you send to many to begin with & then the Deadline is way to short, will keep new work from this Project to a Minimum until things change ...

Hello,

We have generated a new group of workunits with a bigger deadline. In the next hours we will explain it more in the news section.

Thank you for your advices!
