When I Einstein installed my computer crashed ...
so after fixing the problem (better setting of Ram Drive) :-) I got around 100 unit that will not be computeon my profile, is there a way to flag them as error on our profile, or the only way is to wait until the time expired (15 Jan)

:-)

If you mean that the work units show on your account as downloaded to you but you did not get them, then there is not a lot you can do but wait till they pass their deadline.
They will then be re-issued to someone else.
This happens every now and then to a lot of people.

It could also limit any more work requests from the project, the project thinks you have heaps of work, when you don't. You will just have to process something else till they time out.

Hi allo, welcome to the

Hi allo, welcome to the Einstein project.

I took a look at your computers and there are two separate host IDs showing. Apart from a different BOINC version, the two hosts seem identical. I'm assuming that you reinstalled BOINC after the initial problem and in the process you were given a new host ID for the new install. The first install - ID=11713629 has 105 tasks, all 'in progress'. The second install - ID=11713672 was done a couple of hours after the first and has 15 tasks, all of which have been successfully completed and returned.

If my assumption of one physical machine with two separate IDs is correct, you can easily retrieve all the 105 'lost' tasks and then either crunch them or abort them, as you wish. Of course, with your very nice machine, the project would love you to crunch them :-).

The first thing you need to do is check your computing preferences on your account page on the website to make sure you have nice low settings for work cache size. That way you wont get another 105 tasks in one big hit. Until you see how things go, I would suggest you look under the network usage section and set "Computer is connected to the Internet about every ..." to 0.5 days and "Maintain enough work for an additional ..." to 0.1 days. I'm assuming that you are using website preferences rather than local preferences in BOINC Manager. If you're not aware of local preferences then you are using website preferences.

Once you have done that, you need to 'merge' your two separate host IDs. You can do that by going to your account page on the website and clicking the 'view' link for your computers. Then click the 'details' link for one of the two machines in your list (it shouldn't matter which one you choose). Right down the bottom of the details page, you will find a 'merge' link which you can use for the purpose of merging duplicate records for the one physical machine. During the merge process it should tell you that it's going to merge the two particular IDs that I've quoted to you above. If so, you should tell it to proceed. After the merge you will have a single ID (11713672) and the 105 lost tasks from the old ID should be resent to the merged ID. This should happen in batches of twelve tasks and you will need to click the 'update' function on the projects tab of BOINC Manager - advanced view (the ONLY view to use if you want full information :-) ). After each 'update' click you should check the event log to see the details of the tasks that are being resent to you.

I hope you are able to follow the above description. It's several years since I did something like this so I'm a bit rusty on the details. Let us know how you go and I hope you will crunch the 105 lost tasks when you get them :-).

Cheers,
Gary.

One note to that, this project has old server software, it's scheduler will resend work even with No New Tasks selected, other projects with newer schedulers will only resend work if Boinc asks for it in the first place,
It'll mean that every time you complete and report a task, you'll be resent another 12 tasks.
