Hi Thierry,

Tks for the reply.

1) Resource share:
SETI, Predictor, LHC and Einstein all set at 22.5% (but with LHC non-operational, that means these should all be around 30% each approx)
CPDN (having a very long deadline) set to 10%.

Therefore, my assumption being that the WU time is around the same for these 3 projects, "should" mean that BOINC deals with these in deadline order.

But what has happened is that I've already run out of Predictor units, BOINC is now switching between CPDN and SETI, leaving the Einstein WU's untouched (not 1 even part crunched).

2) the number you set to connect to the server

I don't call any number, as I have an 1Mb ADSL (always on) net connection.

3) This might help - my BOINC network connection is set to connect every 1-3 days (but usually returns completed WU's straight away).

4) And we're talking about a 3GHz Pentium 4 here, not some slow 20Mhz 386 (if anyone remembers THEM !!)

Does that help explain?

regards,

Timbo

2 factors are paying a role:

1. the resource share,
2. the number you set to connect to the server.

If your settings are done in an appropriate way, you should be able to get all the WU's of any project to return the results on time.

If you have some WU's past their dealine, either you downloaded too much WU's either you should change your resource share.

Hi all,

Wonder if some-one can advise me about how BOINC prioritises project WU's.

I run BOINC v4.19 on a few PC's but on one, BOINC has prioritised (of it's own accord, apparently) that it should crunch certain projects WU's (CPDN, SETI, Predictor) where the "Report Deadline" is much later than the deadline for another project (Einstein).

The result is that I've now missed the deadline to return a number of WU's for Einstein as a result of BOINC "deciding" that WU's with later deadlines should be crunched first.

Surely, there should either be:
a) a mechanism within BOINC to recognise when deadlines are approaching and to crunch those WU's first, or
b) for the user to be given manual control of which WU's should receive priority.


rgds,

Timbo
