Trusted Computer?

What is a Trusted Computer?
I have seen this term used at times in the forums, and I gather it to mean devices that can be relied on to return results in a timely manner. I try to keep my devices as lean as possible and the settings in line with what I think would make it as reliable as possible, related to work done on World Community Grid.

Are there any guidelines, or suggested settings that would enhance a device, and therefore qualify for a trusted computer?

Re: Trusted Computer?

I think you probably mean "Reliable". wink

Fast / Reliable clients are determined by the following:

The recent average of the length of time between when a result is assigned and the time that the result is reported as done by the client. This time must be less than 48 hours on average. This measurement includes the impact of queue size because a larger queue size will lengthen the 'turnaround time' for a task and push the computer out of the 'reliable' metric.
The host must have maximum daily quota, as at March 7, 2012 that's 120 per day, per active thread. Errors/Invalids reduce this quota value

No messages are presently send to hosts to confirm their reliability state. The "In and "Out" is automatic. No device status page reflects the rating.
Known/regularly contributing hosts must have had "last" 5 returned results validated "at science app level". A new science or an error/invalid requires renewed proofing for that science.

For a full explanation see this FAQ

Re: Trusted Computer?

For completeness, there is a BOINC/WCG definition of a Trusted computer and it's concerned with the Single Validation (or Zero Redundancy) technique (as currently used by FightAIDS@Home - Vina (FAHV) tasks). There's a mention of it in the WCG Help item on "What is Validation?" and in a March 2012 post by Kevin Reed during the upgrade to BOINC 7 on WCG servers. Unfortunately, some explanations and posts have used the word 'reliable' for both the Single Validation and Re-Sent Tasks situations, although the criteria are different.

Re: Trusted Computer?

Thanks Tony!
It seems both terms 'trusted, and reliable' get used and creates some confusion.

I think Knreed summed it up well in his statement:
"trusted' computers (ones that can process non-redundant computations without a wingman) and 'reliable' computers (ones that process resent workunits quickly). "

The 'reliable' computer was what I was originally looking for info on, but now I am much more informed! cool

Thank You.
