i did get Kryptos to run on 1 of my Linux Box's but won't run on the other one. I went thru the same procedure to install V-Box for both of them & their running the same Ubuntu Version 20.0.4. Only difference in them is the one that works has a Intel 3700 & the one that won't run them has a E-5 1620 XEON ...

I don't think it's the Xeon because I have a few Xeons running Kryptos and they work fine, of course they are all running Windows not Linux.

Anyone looking for Kryptos@home - https://www.kryptosathome.com/

Things I've learned about that project:

If you have Windows 10; go back to VBox ver 5.2.44.
VBox Version 6 has issues with their WU's.

If you can't go back from ver 6 for some reason; you can get a single WU, at a time, to run to completion if you pause all the other d/led WU's.

Setting the VBoxSVC.exe to idle priority (using something like Process Hacker) can also get WU's to complete under VBox ver 6 with lower postponement issues.

The invalid rate of restarted postponed VM's is high (over 80% on my test laptop).

The dev says they will develop a native app and do not want to mess with VBox after the issues.

----
Oh and make sure you aren't using your friends old backup drive where you specifically set BOINC to not use Virtual Box in the config file. Lost a couple of hours of diagnostic time there...

If you have Windows 10; go back to VBox ver 5.2.44.
VBox Version 6 has issues with their WU's.
...

Yeah, I can sing a song about that now.
Gave me a hard time the whole day to fix the issue my Win10 machine had with the project. Every wu went to postponed state after a while, and the more you have the more effect does this have to the system - it becomes sluggish and after a while it just doesn't work any more and a restart is necessary.
Don't know why but Win7 doesn't have this problem with VB 6, runs perfectly with it.

One thing that helped me run Kryptos on some machines was a simple app_config.xml file to limit the number of tasks run by it:

<app_config>
<project_max_concurrent>6</project_max_concurrent>
</app_config>

This works for any Project but if you have multiple kinds of apps from the Project it limits all of them to the number you choose, so it's better to use the more complicated one listing each app separately.

For me Krytos was using up to 2gb of ram for some tasks and since some of my machines still only have 16gb of ram I limit them. Sometimes I can run tasks from other Projects but not all Projects play nice and some suspend Kryptos, a simple exit and restart of Boinc seems to restart the tasks. I usually end up aborting the other Projects tasks and not allowing new ones so Kryptos will run. Right now on a couple of my machines I have both Kryptos and LHC SixTrack apps running and they don't seem to care about each other. I did notice that my RAC is dropping for my Einstein GPU GW tasks, I did not expect that as I always leave a cpu core free for the gpu to use on every machine anyway.

About Kryptos@Home.

After some hours of research, I posted my advise to Windows 10 users over at their forums and hope they sticky it till the new WU comes out.
https://www.kryptosathome.com/forum_thread.php?id=17

They are using Boot2Docker, which was designed under VBox 5.x series, and wasn't tested with VBox 6.x and there is a deprecated warning at GitHub.
https://github.com/boot2docker/boot2docker

The devs took a chance going with a well known, legacy, easy startup set of code and got bit in the ass with an incompatibility in the Windows 10 vboxmanage app.

I went back to VBox 5.2.44 on the 2700x Windows 10 box and no issues.
Only need to keep VBox 6.1.16 on the laptop that runs games in VM's and for testing purposes.

Those e5xxx series are pretty old but still see a lot of them on eBay.
Guess my e5-2660 v1's aren't the oldest then...

I was going to upgrade the 3 blades to v2 e5-2692's (compatible with those MB's) but saw a steal for a 8 mo old, custom box, 2700x system w/ 16GB DDR4 on eBay for $432 to host my NVidias

My Windows 7 laptop with VBox 6.1.16 only completed 2 Kryptos@Home WU successfully. 16 invalid from the postponement error.

Mine is an HP 8560 laptop.

Wonder what the difference is between your Windwows 7 installation and mine that would allow yours to work?

If you just exit Boinc give it a bit and then restart Boinc the units will start back up again, but I found that running any other cpu tasks, except the SixTrack ones from LHC seem to cause the "postponement error" again and I have to exit Boinc and then restart it again for them to run again. I ended up aborting all the tasks from other Projects, suspending wouldn't do it, and now it runs fine.

I'm using ver 6.1.? on all my windows pc's and Kryptos works on most of them, for those those it doesn't I just run something else, too many fish in the sea to spend a whole lot of time on it when they are coming out with a non VBox version at some point anyway.

Who knows... there could be a thousand reasons. ;-)
However, it's so different on other VBox-projects, it's just the opposite - Win 7 doesn't work, Win 10 goes...

I tried that on my Win 10 machine also. Sometimes it did continue and even finished the tasks, but these were only a small bunch. Most of the time they either go to postponed again, crash with a "hypervisor" message, kept locked in the slot or whatever.
For the time being I only crunch on Win 7 and let it be on Win 10.

It's a pain with the VBox most of the time. Several years ago I had no probs at all, no matter what project, what version etc. it was, but in the last time it starts to get fussy with it again. ;-)

Could someone who *has* an existing account either post on their forums, or PM the admin?

It's impossible to create a new account, and, therefore, impossible to use the website's facilities to pass this information to the admin.

When you try to create an account, you get this error:

Database Error
Can't create account

Couldn't create account
Field 'venue' doesn't have a default value
Click your browser's Back button to try again.

It looks like a single SQL statement can fix the problem:

ALTER TABLE user ALTER COLUMN venue SET DEFAULT '';

Message Posted 18 Days ago by Daniel:

This project is in the process of being revived in light of comments I have received that optimal primes for two colors and large lengths exhibit strange properties. In particular, the best primes for lengths 23, 24, and 25 are one more than 6 * p, 4 * 47 * p, and 2 * 24 * p, the ps all being primes. Striking in particular is the multiplicative composition of the latter two; 24 = 25 - 1 and 47 = 2 * 24 - 1.

Loop unrolling, faster progression checking, and bit packing have made for a much faster program, making it feasible to run the two-color case up to 4 billion. The computation should give insight into:


The growth of low-color, high-length van der Waerden numbers
The additive distribution of quadratic residues modulo a prime

That's what I did but Kryptos@Home warns in the agreement not to suspend their WU's and they mean it. Any suspension of their WU's causes it to be invalid. Even stopping BOINC to restart the machine will invalidate every one of their current WU's.
You'll see a WU complete in the client but the result on the server will be invalid. Still get my 100+ WUprops hours leaving them rerun at least.

I just got into my account and tried to add you and Steve as 'friends' but the search said neither one of you is there, I didn't expect to find you but it should have found Steve, I copied and pasted both your names so no spelling etc errors meaning the Project still has some issues. I also tried changing my number crunching preferences and got this error:
Fatal error: Uncaught Error: Call to undefined function xml_parser_create() in /home/boincadm/projects/vdwnumbers/html/inc/prefs_project.inc:221 Stack trace: #0 /home/boincadm/projects/vdwnumbers/html/inc/prefs_project.inc(268): prefs_parse_project() #1 /home/boincadm/projects/vdwnumbers/html/user/prefs.php(59): print_prefs_display_project() #2 {main} thrown in /home/boincadm/projects/vdwnumbers/html/inc/prefs_project.inc on line 221

It did see that I had tasks 'in progress' though so hopefully they can extend the return dates and accept them once they are back up and running again.

Yesterday around 4:30 EST all my tasks uploaded but none reported.

I tried to attach my fleet of computers to VDW and got message in BOINC error log that the feeder is not running.

I tried to post to project forums and got same error as STEVE did a few posts back. Also tried the friend search with same result.

Project is messed up. Not sure if Daniel really knows what he ils doing.
