Yep, it keeps track of total time I'm thinking it didn't do that initially but it was fixed to accommodate MT.

BTW, if you are running Yafu this THREAD is a MUST READ. I threw up 900k in a single day and several million over a couple day period until credit new caught up to me

Here is my app_config:

<app_config>
<app_version>
<app_name>yafu</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>1.2</avg_ncpus>
<cmdline>--nthreads 1</cmdline>
</app_version>
</app_config>

The ncpus is a ratio ... read the post to figure out how to set it. What this does is get the MT tasks to run in a single thread ... blows the mind of the credit system
