1) Questions and Answers : Windows : Communication deferred (Message 61104)

Thanks both. It never occurred to me that jobs might be OS-specific. It's not logical to me that anyone wanting to utilise distributed computing would want to restrict themselves by OS-type, but I guess it's just a question of the limits of their own resources in terms of setting up the jobs in the first place.

I only really joined BOINC to contribute to CPDN so it's frustrating not to be able to do so. Absolutely not your fault and thank you for explaining. Amazed at the extent of my own iggorense! I shall apply my CPU time where it's at least useful - I had the machine sitting idle awaiting jobs for a while before I decided that was wasteful. Let's hope that CPDN get some Windows work up soon.

Thanks again.

Please can someone give me a pointer?

I have been running CPDN for years on several machines. I am not IT illiterate, but equally not expert. One by one, the machines on which I have been running it have worked through the tasks that they were assigned and run out of work. This is not unusual if there are no jobs available to download, and so I have been monitoring the situation, but not doing anything about it. Yesterday, after several months of inactivity on CPDN (but BOINC running perfectly happily with Rosetta) I decided I should just check whether or not there were any jobs available. I looked and there were 84 jobs available, so I clicked on 'Update'. I got a 'Communication deferred' message (for an hour).

Nothing has changed in my setup which has served me faithfully for many months/years. What steps should I take to double-check that my preferences aren't precluding me from downloading CPDN jobs please?

OK. That's very reassuring. Thanks a lot!

But it coincided with the Intel Visual Fortran errors which seems a bit unlikely. Should I be worried or take any action? I got screenshots of the Visual Fortran erros but can't work out how to paste them in here otherwise I would!

Just had a couple of the same errors.

Not sure what I need to do now, if anything?
Thanks in advance.

Apologies. Found them eventually.

Having thought about it though, is what you suggest really right? Surely I want to be sure that I have plenty of work for CPDN all the time which means that it should connect whenever it wants to (0 or continuously) and have a big buffer of several days work stored - ?30? (after all, work units of 700 hours or more are not that unusual) and the 'other' project should have relatively infrequent connections and minimal number of work units stored, so that should have, say, 0.1 days?

Hope I've got that right!

Thanks Les - I think!

Sadly either I don't have the two variable you refer to or I just can't find them.

I'm running v7.2.39 and the nearest I can get to what you are talking about is Tools-Computing preferences-network usage where I have two settings that are vaguely related to what you describe: Minimum work buffer and Maximum work buffer. These are on an individual project basis. Are these what you mean?

If so, I assume that I set the CPDN values to a very low Minimum and a 'high' Maximum do I, and the 'other' project to a very low minimum and a barely higher Maximum. Not sure why I'm not seeing field labelled the way that you describe, but perhaps you can enlighten me?

Thanks.

Not sure that this is the right place, but can't see anywhere better. I first got into BOINC via CPDN and I'm very happy that my various PCs run CPDN which I believe in wholeheartedly.

Like so many others, I get sad when there are no tasks available and all that lovely computing power is going to waste, so I like to try and do something useful by occupying the CPUs with something else that I consider worthwhile.

My current 'second choice' is malariacontrol.net which has much smaller work units. To try to make sure that I give CPDN the very best chance of running, I have set the preferences to 99% CPDN and 1% malariacontrol.net which I hoped would achieve what I wanted, namely CPDN running the vast majority of the time but any spare time being allocated to malariacontrol.net.

The problem that this causes is that when there are no tasks available from CPDN, the other project loads up a mass of short workunits with relatively short deadlines, and if CPDN is running, then it gets demoted in favour of the short deadline tasks because they become high priority. So, short of suspending them, I can't get CPDN to run (mostly because it has such long deadlines).

Of course if there were smaller work units then deadlines could be shorter and the problem would go away, but as smaller work units are not an option, is there any way to give CPDN its preferred status ie. to always run as long as there is a work unit available to work on, but not waste capacity at the same time?
