Why is sieving for this project done by yoyo@home and not as a subproject here?

On my machines all the Siever tasks at yoyo abort immediately with a computation error so that project is useless to me.

Why don't you have a GPU sieve app like Primegrid has - PPS Sieve?

In your project information download it mentions the NPLB - No Prime Left Behind - project which is non-BOINC. Is this project SRBase really a BOINC version of NPLB?

On the yoyo forum is a message that there was a error in the input files.

So you may want to have an other try.

Hi vaughan,

Why is sieving for this project done by yoyo@home and not as a subproject here?


Because of the limited ressources in the srbase VM.


On my machines all the Siever tasks at yoyo abort immediately with a computation error so that project is useless to me.


Already on my side, but that was a fault. Now it's running fine again.


Why don't you have a GPU sieve app like Primegrid has - PPS Sieve?


Because for sieving the sr1sieve application is used. There is no known gpu version of this app.


In your project information download it mentions the NPLB - No Prime Left Behind - project which is non-BOINC. Is this project SRBase really a BOINC version of NPLB?


Not of NPLB, but it's the boinc side of the CRUS (Conjectures 'R Us) project.

Regards Odi

Yep, that was me stating that. This error was only for 2 runs because the files had an non-increasing n-value due to an error by creating the input file.

@Vaughan You should now get wu´s without errors. ;)

Anway: Happy new YEAR. (soon.)
