Agree. Kudos Carl for defining what to expect from low end Nvidia cards. Even multi generation old cards are still usable for this project.

You are welcome. :-)
I posted these values, most of all because it's always nice for newcomers to have figures which can give you an idea how long your own GPU will need to finish a work unit, especially if it is 'not so new' anymore.

I must say that a deadline of just 5 days is the shortest I have seen in any distributed project.
Especially now that they seem to have dropped the idea of shorter work units too.
A very short deadline and only big work units...

I don't know if it is a good idea,
but why not extend the deadline to 6 days or even a week?
I don't think that people will become lazy if you extend it by just a day or 2.
Of course, I guess this can influence the server and storage performance needs of the project... the servers must be able to follow.

I remember seeing other projects with much longer deadlines.
Although I do know that a longer deadline may or may not be interesting or workable,
depending on the goal of the project.

To give just 2 examples:
The deadline for SETI, isn't that 2 weeks, or a month? Not sure anymore.
And The climate prediction project has even a deadline of 1 year... That is the longest I have seen to date.

Depends on the project. Storage limits or the size of the database to hold tasks and work unit results have to be considered.

Depends on the scientists need to gather the input data in a short window for publication or for combining with other scientists data.

Seti has tasks that mostly have a 7 week deadline for normal tasks. Some recent ones only had a two week deadline and AP task have always had a 4 week deadline.

Some projects have deadlines of 300 days or greater.

Thank you Keith!

Thanks to information like this,
I slowly learn how these distributed computing projects work in difficult circumstances:
With a lack of funding, resources and manpower.

Now that I think of it:
These are exactly the cirumstances in which almost all scientists and doctors worldwide need to work.
Because our governments prefer to invest in weapons rather than science and healthcare...
So let us volunteers try to compensate.

Warm greetings from a cold and wintery Brussels ;-)

but why not extend the deadline to 6 days or even a week?

The reason for this short deadline has been discussed many times.
The work is generated from the previous result, so if the project extends the deadline by 2 days, the whole simulation could take up to (2 * the number of stages in the simulation) days longer.
If you look closely you can distinguish the different parts of a workunit's name:

test159-TONI_GSNTEST3-7-100-RND0962_0

The most obvious is the last digit: it's the number of re-sends.
The "7-100" means it's the 7th stage of the 100 stages.
Every stage is a workunit, the next stage picks up exactly where the previous finished.
If the deadline would be 2 days longer for each stage, the whole series could take up to 200 days longer.
The present 2999 workunits in the queue are actually 299.900 workunits.
Different batches are split up to different stage sizes, depending of how urgent is the actual simulation for the project.
If the present simulation have been split up to only 25 stages, the workunits have been 4 times longer.
Less stages * short deadline = short total runtime
More stages * long deadline = long total runtime

I must say that a deadline of just 5 days is the shortest I have seen in any distributed project.

At WCG Fighting AIDS at Home 2 is 24 hours and Africa Rainfall is likely to shorten to about 24 hours.
I know it's frustrating but these molecular modelling projects require an enormous amount of work so they need to tighten it up so they can get the results and wet bench them.

I think Rosetta has some now and then with a 3 day deadline. At least they have in the past.

Could anybody please tell me whether it worth to buy a RTX 2080Ti GPU for Gpugrid, or may be any other modern but cheaper GPU will look more attractive in terms of сredit per €/$?

Probably not. Find someone with a 2080Ti and look at the task times and then find someone with a 2080 Super and look at their task times. Then compare the percentage improvement of the 2080Ti to the percentage increase in cost.
Problem becomes I don't think the scheduler individually identifies the different 2080 models and then all just get lumped together.
