1) Message boards : Number crunching : Sudden credit loss (Message 5779)
Posted 20 Mar 2020 by ardo
Just coming back to SRbase after several weeks and I noticed you corrected most of the credit loss, except for the following:

* Sierpinski Base - short is missing 491,310
* Sierpinski/Riesel Base - long should be 10,010,745
* Sierpinski/Riesel Base - average should be 5,770,205

The last two mysteriously got a lot of extra credit they should not have.

Thanks for all the work on this.

Everything on the server status page shows Ubuntu as the OS, why is there a Windows point of failure at all? Windows 10, is it a LTS build? I don't like running Win10 on my desktop, but I also play games that will not run on Linux.

How much work was lost? What was the cost of trusting MS?
Giving the hardware a pass may be wrong, but I'm assuming we're running on enterprise gear, that may be a false assumption on my part.

Ubuntu is the Guest (running in VMware under windows10) I need both systems. A VM can be moved to another place too.

Could you do it the other way around, make Windows the guest of the Ubuntu system?

Or run VMware ESXi as bare metal hypervisor with the Ubuntu VM and then Windows also in a VM?

Now we just need a fresh batch of those small tasks. :-)

I can understand that limit of 10 for the long and average tasks, but not for (very) short tasks. Especially for the sub-15 seconds tasks (on my hosts, that is) the cores are more often than not busy doing nothing while waiting for the boinc client and boinc server to finish their spiel of uploading/reporting/downloading. A higher limit would keep those cores (more) busy doing real work.

Just FYI: I do not know what happened and what, if anything, got changed and/or cleared up where, but since yesterday the WUs are flowing as smooth as before I reported the issue in this thread. Life is good again. :-)

The situation has not changed: Most of the uploads, reports and downloads are OK, but there are quite a few retries, double retries, and even triple retries. And once the uploads succeeds, then there is the wait for the reports to succeed and then there is the downloads with a similar number of retries.

I also noticed that some of the download issues are of the "project deferred for large number of minutes" category.

The cache is set to 0.1 day. For the (very) short tasks, say less than a minute, that is not sufficient, with the maximum of 7 WUs per core, to survive all the retries making the running idle from time to time. For the longer tasks the cache is sufficient to keep the cores busy continuously.

I put one of the hosts temporarily on PrimeGrid doing ESP/PSP/SoB sieving and it all went without any issue whatsoever. And in all the years of doing PrimeGrid WUs I never had this issue.

Maybe this project simply does not want me to process that many WUs... ;-)

Some further data: I rebooted all the hosts as well as all the networking equipment, up to and including the cable modem, and the issue persists.

Could this be an issue between the Internet and the host you're running this one, like e.g. a firewall?

To gather additional data: I did some tasks from Milkyway@Home and they all went through without any issues. Then I switched back to SRBase and the first update command resulted again in "failing to communicate".

Interesting. Is perhaps the database server "busy" which on its turn makes the web server "busy"?

By the way, I switched the hosts to long tasks and average tasks to keep them happily crunching...

Since this weekend new work got uploaded to the server I see a lot of messages "Project communication failed" on all my hosts resulting in my hosts being more idle than productive when trying to do the small tasks.
