ARGOMENTO:

Hi folks,

seriously, I don't why 6.6.20 became a recommended version. It has serious issues with work fetching, scheduling and debt handling. We expected problems due to this, but as it turns out another of 6.6.20s flaws is hitting us hard:

There are massive complains about WUs taking forever. This is a bug introduced a few versions prior to 6.6.20 and fixed in 6.6.23. So if you want to run a 6.6-series client, upgrade to 6.6.23!

This version still has issues, so if you don't like these I recommend 6.5.0(*), which doesn't have any of them. The only issue I know of is that it doesn't differentiate between cpu and gpu projects regarding the ressource share, so be sure to put in some balanced numbers. For 4 cpu cores and one gpu give GPU-Grid about 20% ressource share, otherwise your cache will be messed up.

You could also use 6.4.7 (the old recommended version), but this may require using a cc_config.xml to use all cpu cores.. so why bother.

All versions can be found here.
