Aborting now, time limit reached. A lot of waste time.
2) Message boards : Number crunching : WU 9 days over deadline (Message 843)

I check the running WU as follows:
- Open file factor.log from folder Boinc\slots\nn
- check if new lines are generated at regular intervals
- check taskmanager, details, if programs active with filename like: gnfs-lasieve4I13e.exe.

The Boinc Function "Show Graphic" show you the type of sequence. If it is a Open End then it take a long time to find the next number.
When the job is finished I check the factordb.com for the new result.

Sample of factor.log:

3) Message boards : Number crunching : why does it need all 8 cores to run (Message 832)

I see the same effect. But I think, it is because of short running tasks. The ecm.exe runs between 3-15 sec and it comes to overlap.
I use following settings:

<app_config>
<app_version>
<app_name>yafu</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>4.0</avg_ncpus>
<max_ncpus>4.0</max_ncpus>
<cmdline>--nthreads 4</cmdline>
</app_version>
<app_version>
<app_name>yafu-low</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>4.0</avg_ncpus>
<max_ncpus>4.0</max_ncpus>
<cmdline>--nthreads 4</cmdline>
</app_version>
<project_max_concurrent>1</project_max_concurrent>
</app_config>

project_max_concurrent
limited the project to start only one job/Wu.
One job is using 4 cpus. I can follow the progress in factor.log.
