I stopped crunching for Sztaki some while ago, due to the problem with the unpredictable wu length and the (for me) inexplicable way credit was granted. All these issues were mentioned in the thread \"How long is short\" (http://szdg.lpds.sztaki.hu/szdg/forum_thread.php?id=437)
Now, after some inactive time, I would like to get some work on my Mobile AMD Athlon 1800+, but I wonder whether it could deal with the wu length in a meaningful way, while crunching also for other projects.

Could somebody please tell me whether the old problems got resolved and whether my slow laptop can be of any use here. I would just hate to lose my valuable CPU cycles and/or risk not to be granted any credits.

lots of wus means a load of work, hope you have some years spare.
i am at 40% with 65 hours crunched.


I spent nearly 190 hours on 1 wu, which should have gave me 1100 credit. I noticed the others who downloaded the same wu aborted, so it couln\'t be confirmed. Just checked & that wu has been deleted & I have not had any credit. You would think that the amount of time I stuck with this wu, I should have got something.

Is this going to be the norm & should I not bother with SZTAKI if you cannot guarantee that the work you do you do not always get credit

I hope this has been corrected - as I have downloaded lots of WU\'s recently and have just started crunching them.

I would still very much like to get some feadback to those questions, as i am running sztaki since several days, so that their wus can finish.
another observation is, that wus that are finished and pending for me, do not get sent out again if they are being cancelled by other users (id= 650 and 1900).

my wu is now at 40% with 57 hours crunched. If this effort would get lost, i\'d be very dissappointed, as i only have one private cpu and do not intend to waste its time and my electricity.


I think it would be very important for the future of this worthwhile project (and in order to keep it\'s crunchers base) that Adam makes a clarifying statement on the news page. Climate prediction wus take a real long time, but nobody is having a problem with this, since we know that this is the way they work.
Here we always had nicely short wus and suddenly they are not finishing after 10 or 20 hours. If I understand it right, the time to completion won\'t show up correctly mainly because:

- it is based on the old estimates from the short wus (potentially giving me an overload of wus i won\'t finish in time)
- the progressbar jumps in a non linear way, i.e. from 0% to 100% if there is one \"step\" to calculate, from 0% to 50% to 100% if there are two \"steps\" etc.

I would thus, in addition to the plea to make a statement on the news page, have two questions:

1) Is there a way to guess ourselves from the completion time for one \"step\" the total amount of time neeeded to finish the wu. As a simple example: if 50% take 10 hours, does the wu take 20h, or can the two \"steps\" have a different duration?
edit: apperently every step is of different length as some report here.

2) I have a wu in progress which crunches since 20 hours and shows 10%. Does this mean that the next step will be 20%, thus the wu having 10 \"steps\"?

I hope these questions and statements help the project as well as us to understand what is going on on the crunchers\' as well as the project\'s side.

I see a similar problem: Even if one user sticks to the wu and completes it, what are the chances that all other users wouldn\'t abort it. i have two wus running worth already 56 hours. if they do not get validated with a quorum the effort is totally lost and would have better been given to other projects.
i really urge the project officials to deal with these issues (also stated in the thread \"how long is short\"). otherwhise you risk losing your user base. trust and patience are crucial with all those other wortwhile prjects out there.
