I just realized that, since approx. 1 hour, for my 4 core machine there is a daily task quota established of only 8 tasks:

18.01.2018 18:37:22 | Rake search of diagonal Latin squares | Sending scheduler request: To fetch work.
18.01.2018 18:37:22 | Rake search of diagonal Latin squares | Requesting new tasks for CPU
18.01.2018 18:37:23 | Rake search of diagonal Latin squares | Scheduler request completed: got 0 new tasks
18.01.2018 18:37:23 | Rake search of diagonal Latin squares | No tasks sent
18.01.2018 18:37:23 | Rake search of diagonal Latin squares | No tasks are available for RakeSearch
18.01.2018 18:37:23 | Rake search of diagonal Latin squares | Nachricht vom Server: Ihre app_info.xml Datei enthält keine nutzbare Version von RakeSearch.
18.01.2018 18:37:23 | Rake search of diagonal Latin squares | This computer has finished a daily quota of 8 tasks

This apparent server-wise setup leaves my systems idle for most of the day so that, unfortunately, I will have to look for a diferent project.
Are you runing out of work or what is the reason behind this?

Dear Michael, thank you for observation. It looks strange. I increased this value to 128.

Well, with approx. 1 hr of run time per task, on an 8-core machine, this also equals to only 16 hrs of continuos contribution to your project. Better further increase this value to 256. There are also server machines with >8 cores active, I guess.

Michael.

Hello Michael!

Better further increase this value to 256. There are also server machines with >8 cores active, I guess.

We analyze, a list of top computers and could not find a problems with workunits for hosts with many cores. But we increase this parameter up to 256. :)

Happy crunching!
