Hello,

I have a question.

When I create a work_unit, and run it in only one Client machine, how many tasks would be created?
One task runs exactly one slot directory.
So in other words, how many slots directory would be generated when i just create one work_unit and i have only one Boinc-client.

I would appreciate for your help.

Depends on the minimum quorum you set in https://boinc.berkeley.edu/trac/wiki/JobIn.
Normally one task per slot directory, one task per work unit. Two tasks when you validate tasks against each other, but I think that you cannot run both tasks on the same computer without some database hacking.

The first part is correct. The last part not. Whether both tasks of a workunit can be run on the same computer is set in config.xml by the options <one_result_per_user_per_wu/> and <one_result_per_host_per_wu/> see: http://boinc.berkeley.edu/trac/wiki/ProjectOptions#Joblimits this is to ensure that a malicious client can not tamper both results of a single workunit.
