...it was stated by Eric that this is being done to try and keep the system within it's RAM limits, I just can't remember where that post was made and whether Eric actually made it or it was passed along ATM.


It's actually right in the News forum so visible in the BOINC client. (Edit: of course it was there yesterday and now that I post this it's disappeared lol.)

Thanks Mr Kevvy, I was suddenly very pressed for time just as I started to make that post. :-)

Cheers.

I can't help wondering if the splitters are being deliberately throttled in an attempt to reduce the amount of work sitting around in the various queues. After all work not being split will have that effect
Yes they are, it was stated by Eric that this is being done to try and keep the system within it's RAM limits, I just can't remember where that post was made and whether Eric actually made it or it was passed along ATM.

Cheers.



While that's been affirmed, I'm not seeing any improvement on the number of items waiting to be satisfied.

I don't think any real improvement will happen before whatever problem is preventing the assimilator from assimilating has been found and fixed.

It's not going to improve until it is possible to remove the extra replication required to protect against bad data going in to the science database.

@ Jimbocous
I'm still convinced that somehow, whether it be intent or just net result, the higher your RAC is the lower you are in the priority stack in terms of actually getting work during a recovery from outage.
It is NOT an accident. It is intended to be that way.

From the "FEEDER" code that prepares work to the scheduler:

// The feeder tries to maintain a ratio of committed to uncommitted
// (generally 50/50) and, of committed jobs, ratios between HR classes
// (proportional to the total RAC of hosts in that class).
// This is to maximize the likelihood of having work for an average host.

We don't use HR classes here. That code was developed for Einstein@Home's needs, and so far as I know they are still the only project using it.

Thanks for making that clear.

Do you have knowledge of what parameters are used with the programs or where I can read
them? That would help in analyzing things when reading through the code. The actual
in-production parameters being used, not the ones in the code.

Sorry, no. BOINC servers have a large number of configurable parameters: some of them probably need to be kept private for security reasons, although others could perhaps be made public. But I don't know of any project which routinely publishes the whole set, or even any significant fraction of it.

The options which are available are listed at Project configuration: special cases, like Einstein's use of Homogeneous Redundancy, you have to discover by reading each project's discussion of their scientific goals and methods.

Thank you. I like authoritative sources better than anecdotal answers.

Hi Jord,

What news, pray tell? Is SETI shutting down for a week to upgrade servers? Are they shutting down for a week to rewrite the database? What? ;)

Have a great day! :)
