Hi guys,

I read a bit about the boinc system and found some interesting infos about possible work unit distribution. The two most teriffic features for RALPH are:

max_wus_to_send:
Maximum results sent per scheduler RPC.

min_sendwork_interval:
Minimum number of seconds to wait after sending results to a given host, before new results are sent to the same host.

I think with these two parameters one can stop the stockpiling effectively and reduce avg. return time dramatically;

max_wus_to_send: 1
min_sendwork_interval: 1h

This means every host gets only one WU per request and can ask for an additional WU only after an hour. This will lead to a more equal distribution of WU and prevent the first lucky hosts to grab each 20 WUs. It will still allow them to ask for another WU every hour though.

So if I were the work unit distributor of RALPH I would use the following parameters:

deadline: 5 days
daily quota: 10
max_wus_to_send: 1
min_sendwork_interval: 1h

What do you think? Let's discuss the best settings here and propose them to Rhiju after we agreed.

I think the quota should be lower, 2 or 4, other than that those look like good settings for a test project.

I think 4. It takes atleast 2 errors to start seeing a pattern, then others would be needed to narrow it down.
