In my online preferences, I see "Total disk space" that is still my very old harddisc that I had when first joining a BOINC project. I haven't found any preferences page where i can change this size ... am I blind?

BOINC 7.2.42 (x86_64) on Linux Ubuntu 16.04 (64 Bit), AMD APU 7850K 3.7 GHz, 32 GB RAM.

Depending on BOINC version:

Pre 5.8, go to the project website, your account, general preferences, edit general preferences and set the amount of disk space you want BOINC to use, save changes to the website, Open BOINC Manager, select the project you changed the preferences at and press Update.

5.8, BOINC Manager, View, Simple View, Preferences, check "I want to customize my preferences for this computer only" and change the disk size preference. Click Save.

5.10, BOINC Manager, Advanced View, Advanced, Preferences, Disk and Memory Usage, set the disk space you want to use and click OK.

I have BOINC 5.8.17 on Ubuntu Linux 7.04 and there is no "I want to customize my preferences for this computer only"! My preferences dialog looks like this:

This "use no more than 20 GB of disk space" is something different. The old value I can't change is 75 GB.

The old value I can't change is 75 GB.

And where do you see this number? Perhaps when you start up BOINC?

But else, really, go through the project's website as I said in option one. The preferences in Simple View 5.8 and higher and those in Advanced View 5.10 or overriding preferences. They will override the preferences set on the website, for as far as there is an option for them in the 'onboard' preferences. So for Simple View it's only partial, for the advanced preferences in BOINC 5.10 it is total.

Now, for aesthetics, not that it matters if you set 75GB or can set 250GB. I doubt you are attached to so many projects that you need the amount of space for BOINC to store its project related stuff in. Maybe if projects go run 4GB and bigger sized results that you need it, but as long as they are mostly measured in mere kilobytes, the odd project excepted, it's really not necessary to worry about it in chances of getting work.

I can see this old value in every project website status page of my account - and can't change it there. I read somewhere the the amount of credits is also calculated by the size of the harddisc ...

And as you can see in the screenshot above, there is no such preferences field in the simple view preferences.

I'm not sure where you read that, but it's incorrect information.

For those projects that run without a Floating Point counter, credits are measured by runtime times the benchmarks. And those projects that do use FPOP counting, use the amount of floating points a result took times an internal multiplier.
There are even projects which give credit that's set by the server.

But none are giving out credit based on the amount of space you give BOINC to use, or the size of the disk in total.

Are you talking about the free space reported by BOINC in the startup messages? I believe that is read from the OS. It's then stored in client_state.xml (I think as I'm doing this from memory) and then passed to the project servers.

What should it say? And what does it say?

Is it correct in the startup messages from BOINC and just wrong on the host page at the individual project? Or are the start up messages wrong as well? If the start up is right and projects are wrong, have you been attached to those projects since upgrading the hard drive?

Is BOINC installed to its own partition? Or is the hard disk one big partition?

Sorry for all the questions. I'm just trying to understand what's going wrong for you.

Well the project pages say this, e.g.

Rosetta@home > Computers at this account (View) > (Click Computer ID) > Total disk space: "76.77 GB"

SET@home > Computers at this account (View) > (Click Computer ID) > Total disk space: "76.77 GB"

Years ago, when I first used SET@Home (classic) and migrated to BOINC SETI@home, I had a 80 GB harddisc (with several partitions) - on Windows. I upgraded every now and then to a new BOINC Version, also upgraded my computer and also my harddisc (now: 500 GB with several partitions). So, this value "76.77" once was the (total) capacity of a former harddisc and I can't change this value via edit preferences (or anywhere else I've searched).


Well, I found the page were I read this about the hard disc storage for the point calculation: World Community Grid (http://www.worldcommunitygrid.org/help/viewTopic.do?shortName=points):

"Hard Disk Storage: On your preferences page, you set the megabytes of hard disk space allocated and available to World Community Grid projects. The lesser of the amount of hard drive space allocated and the amount of total space available on your hard drive partition, is divided by the Hard Disk Storage value of World Community Grid Comparison Device. The result of this calculation is then multiplied by the run time used to complete the work unit and return the results to World Community Grid Servers."

So, the harddisc storage is taken into account when calculating points - right?

BOINC 7.2.42 (x86_64) on Linux Ubuntu 16.04 (64 Bit), AMD APU 7850K 3.7 GHz, 32 GB RAM.

Maybe on the United Devices Agent it is, but not on BOINC.

Please look at http://www.worldcommunitygrid.org/help/viewTopic.do?shortName=linpointscalc#177

WCG uses the UD Agent (stand-alone application that you can crunch all those projects with) and the option to crunch for them through BOINC. That may be confusing.

Why don't you see http://boinc-wiki.ath.cx/Credit for more?

And as for the size factor, more questions:
- How big is the partition that BOINC lives on?
- Are the projects you name 'live'? In other words, are you actively crunching for them and have they had recent scheduler contact with said projects?

The installation partition (my /home directory) is 49.7 GB and in BOINC manager, tabulator "Disc" it also says:

free disc space: 49.69 GB
used by BOINC: 993.61 MB
used by other programs: 26.11 GB

Yes all my 4 projects (SETI@home, climateprediction, Rosetta@home, World community grid) are live and crunch (even though since today, Rosetta isn't doing anything anymore after my first work unit finished with a client error yesterday (the task tabulator just shows WUs of the other 3 projects).

Is it possible that you only made the Linux partition 76Gb when you installed Linux?
