If your new computational resources are sufficient, don't feel the need to "make work" to keep crunchers happy, I have several "silent" projects on my machines, every now and then, one of them pushes a couple of weeks work, then goes silent again. Remember, the crunchers are trying to help you, they should never be a burden.

What purpose do these badges have?

Does the ARM version have issues is the point really.

One of the things that struck me was the run times. The ARM systems had at least ten times the run time of my systems, if their results are being dumped, that is serious waste.

Eleven hours later, and the two units have been validated for me. I should have noted the unit numbers so I could see what had actually happened, but I didn't.

I happened to look at my recent results page and noticed I had two marked as "Validation inconclusive". One each from my two i7's. In both cases it´s partner is an ARM v7 processor. Potential issue here?

A possibility.

The part you need to understand is :

>>> Multithreading is only practical for certain types of problem. Applied to the wrong system, it can cause an increase in run time.

I presented a stupid example of where multithreading a task can make it run slower.

My old website had a tutorial about multithreading, it uses a very silly program as the teaching tool, and I wrote it almost two decades ago, so some things might be different now. The way back machine has the tutorial here :

https://archive.org/web/web.php

...then ...

search for adrianxw.dk

...then ...

click the most recent date, 15th Feb then click "Enter software site". Parts 1, 2 and 3 of the basic tutorial are on the list there. Watch them in order.

I've not used that site for years, but it seems to work anyway.

Multithreading is only practical for certain types of problem. Applied to the wrong system, it can cause an increase in run time.

An extremely crude example, suppose you have a task which does a loop, each iteration of the loop adds 1 to the total, you have to iterate the loop 10 times to get the answer. Simple enough to do, but how could you multi-thread that? Each time it goes through the loop, it needs to know the result of the last pass through the loop, so thread 2, can't start until thread 1 is finished, etc, until it is complete. The act of starting the threads, passing the data, recovering the results, all add to the run time.

The current units run in about three hours on my i7-6700 systems running Windows 8.1.

... may be of interest in this respect. Go for it, most crunchers have a list of projects they support, if one or two only supply a couple of workunits a week, well, no harm done is there.

That would alert current BOINCers, sure, but the real point is to get more BOINCers into the mix. I've found that most people that see "something odd" running on my computers, ask me about it, and once explained, they are keen to get going themselves.

I tend to trawl the list at boincstats.com every few months to see if any new projects have arisen. The BOINC pages say "about 30" projects to choose from, but boincstats lists 50 actives.

>>> we definetely need to gain computing power somewhere

I wonder how many times that has been said by the folk at the various projects!

I think one of the biggest problems is that the projects and BOINC in general, are not well known. I sent e-mails to the companies that do the "after the news" evening chat shows suggesting a five minute slot to push BOINC generally, but never had a reply.

Another problem I discovered is the licensing of BOINC, it contains wording with warnings saying that it "has never caused problems", "used without issue by millions", etc. etc. I tried to get permission from the local council to put BOINC on the general purpose computers in the local library, they refused saying they could not trust it because of this, rather soft, wording. I could assure the council it was harmless as I'd never had any trouble with it, or the older Seti@Home that was the predecessor of BOINC in the last centuary, but that is just me.

Something to remember with research, is that it is rarely possible to say in advance, how long, how many, how much etc. What tends to happen is that a project starts with a good idea of where it is going, but as the results start drifting back, some suprises appear, these can lead to additional types of jobs, different techniques etc. If you look at the history of other BOINC projects, you will see this again and again.

You are, indeed, quite correct. I found the item and have adjusted it. What a ridiculous state of affairs. Thanks for the heads up.

On my home page, at the bottom, is a list of other projects I am or have crunched. I noticed that Einstein was missing from that list.

Fine, your project, your choice. You also understand there are costs. I've set no new tasks and will detatch when those here are cleared. Best wishes.

Well, as admin, you now know the consequence of having the invitation code. You can't expect team admins to push your project.
