It's great there's new work, but it'd be even better if it would actually let machines requesting it HAVE some.

I think I know what it is. I come back to this project intermittently and this time I did so with a VM that hadn't been on it before. Of course it put me on a limited number of work units until I return some successfully. I aborted the batch 1005 unit I had and the other three are still running. I'll just have to wait until I return at least one successful unit.

For some reason it's not letting me have any.
I upped the number of CPU cores and RAM in my VM last night to do more, extended my work cache settings, and freed up disk space, but it's still not giving me any more than the three I currently have.


What's your client log say about the reason it's not requesting new work? There's usually some obvious-ish reason listed.


22/02/2024 00:52:38 | climateprediction.net | Sending scheduler request: To fetch work.
22/02/2024 00:52:38 | climateprediction.net | Requesting new tasks for CPU
22/02/2024 00:52:41 | climateprediction.net | Scheduler request completed: got 0 new tasks
22/02/2024 00:52:41 | climateprediction.net | No tasks sent
22/02/2024 00:52:41 | climateprediction.net | Project requested delay of 3636 seconds

That's all I'm getting for now, I'll enable a few more logging options and see if anything new comes up at the next update.

So is there any word on when further new work will drop?
Server status currently showing 704 tasks ready to send, though doubtless that has dropped a bit since the last server update. I am guessing it may not be till next week that we get another of the batches that was mis configured sent out. The person who normally sends batches out is away and I don't know how much time Glenn has free to do this. If he doesn't have time it will have to wait till the person who normally does it is back.

Edit, 704 was from the newest batch. there were also a few retreads from 1001.

It's a simple and reversible change if you want to try it.

Network and Internet > Change Adaptor Settings > (select adaptor, I double clicked) > Properties > Configure > Advanced Tab > Large Send Offload (IPv4) > set to disabled > ok and close back out.

There's probably a quicker way to that menu but that got me there.

Post:
Which network adapter are you using with VirtualBox out of interest? eno1 or wlp6s0? I checked my Win10 VM and I have wlp6s0 enabled (aka wireless), which strictly speaking I shouldn't have for bridging but I was lazy and selected the first option. Curious to know if the problem only affects the ethernet adapter, eno1.

I was also reading this article about problems with the default VirtualBox ethernet network adapter being the root cause:
https://petri.com/how-to-improve-network-performance-in-windows-virtualbox-guests/
It suggests installing the virtio-net adapter type for better performance. I was trying to check the driver was not junk when I saw your fix. I might still try this though.

Ok, I did a thing. It appears to have worked. In a sense I was right about not having this problem if they were linux tasks but only because if they were I wouldn't be using a VM to run them. The problem is a bug in the Virtualbox Bridged Network adaptor.
The change I made wasn't NAT, it was to the Windows network device driver settings.
Specifically I disabled “Large Send Offload (IPv4)” in the adaptor settings.
BOOM! Next upload file runs at 2000KBps instead of 3.2

I found the solution here in the last post: https://forums.virtualbox.org/viewtopic.php?t=110486


I have different adaptors to you, I think it's host specific. This is the selection I have:
(can't attach a picture so I'll have to type it out)
PCnet-PCI II(Am79C970A)
PCnet-FAST III (Am79C973)
Intel PRO/1000 MT Desktop (82540EM)
Intel PRO/1000 T Server (82543GC)
Intel PRO/1000 MT Server (82545EM)
Paravirtualised Network (virtio-net)

I found my VM refused to connect to the network with either of the PCnet adaptors or the Paravirtualised adaptor and had the same issue with all three Intel adaptors.
The adaptor name in my case is enp7s0 (Ethernet) with the options of wlp6s0 (WiFi) or ham0 (I run a VPN to my home server for my mobile devices)

I saw one upload go at over 3000KBps just now. That's rather a spectacular improvement over 3.2KBps for what amounts to a very simple change.[/img]

I changed my VM networking from Bridged to NAT to see if it makes any difference but I'll have to wait until the server unlocks the files again.
I doubt that'll make any difference as that just affects how the VM appears on the local network. The outside world only sees your router IP address, not the local IPs.


I figured that, but thought it was worth a try. It just made my proxy logs harder to read.

This may or may not be relevant but my home proxy hard blocks traffic to Chinese, Russian, and Belarus IP addresses.

That IP times out often when I repeat the trace.

Just had an upload run 8.5 hours only to crash and restart.
This is ... not enjoyable.
Odd. I just looked and all your running tasks are the wah2ri ones which means they are east Asia and not the NZ ones where there is a server issue. I am averaging 55KB/s uploading the eas tasks. I wonder if doing a traceroute on the server from your end would show anything or if any other users from Australia might check to see what speed they are getting? (I know I am probably clutching at straws here but otherwise I am out of ideas.
http://upload7.cpdn.org is the server the EAS tasks are going to.

It's a wee bit rude promoting a crunching competition on a project that isn't included in said competition, don't you think?
Rude or not, it does mean I won't be taking part as I only go to other projects when CPDN has no work., though I can understand a competition not including a project that may have no work when it actually starts/runs.


It's quite common for there to be projects in the competition that have intermittent work which isn't a huge deal since it runs over the whole year. Fair enough to exclude it for the 3 day sprint events, the length of the workunits alone could make that problematic, but as a marathon project it would be fine.

I suspect if the work was available in Linux I wouldn't be having these issues.
I suspect the issue is at the remote end, Linux tasks wouldn't make any difference. I'll get in touch with the project scientist.


That would be greatly appreciated, thanks.

Formula BOINC 2024 re-launch

I am acting as admin for the above group and I wanted to let you know that the Formula BOINC website has been updated for the 2024 Season.

And that the Sprint Season will start on 29th February - just about 2 weeks time - so please help publicise Formula BOINC to your team members so that they can take part.

For Teams:
Teams previously registered to take part in these regular BOINC Challenges in previous years have been included for this season and Teams have now been allocated to one of 3 Leagues, depending on their performance in 2023.

If your team is NOT registered already, please ask your team founder to register (via the FB website)

Registered Teams are listed here:

https://formula-boinc.org/teams.py?race=0&division=1&standing=team

And it would be really good if your team members can take part and support the various BOINC projects throughout the forthcoming year.

As many teams are already registered, members do not have to do anything EXCEPT to make a note of the date and time when the Sprints will be taking place and to ensure that they are crunching tasks from the chosen project.

This information will be displayed on our website here:

https://formula-boinc.org/sprints.py?race=0&division=1&standing=team


For members:
We also have a Members League so that individuals can compete against one another - this is entirely voluntary but it can be rewarding to know how well you are doing when compared to other FB members - even those in the same team.

If any team members have not already registered, then there is a webpage that you can visit and register, which is here:

https://formula-boinc.org/howtoregister.py

And finally for all the latest news about Formula BOINC, we would ask members to visit our forum:

https://formula-boinc.org/forum/index.php

I do hope teams and members will support the Challenges and by doing so, this will help the many BOINC projects who need the support of volunteers in order to continue their research.

best regards
UBT - Timbo
Admin for Formula BOINC


It's a wee bit rude promoting a crunching competition on a project that isn't included in said competition, don't you think?
