Good stuff, I'm going to lock this thread for now, because on review the value was actually set at 8* (nGPU + nCPU) which shouldn't only dish out one task.
If this behaviour continues, please start a new thread. Thanks

We have pushed out a change to set the minimum required version of OpenCL to 200 for Intel graphics.
This will remain in place until we have tasks which may be compatible with older versions.

Those shouldn't have been modified from default, all of the configuration for our BOINC server can be found here to validate.

I'm glad, we also pushed a change today to specifically resolve this issue.

In the last news post, I advised everyone to create a profile in order to be eligible for 'user of the day' selection.
Unfortunately, there was an issue with the ReCaptcha implementation which prevented this. This issue is now resolved.

Now, you are able to create a profile here.

Also, good news for hosts with OpenCL capable hardware from more than one vendor (e.g. an Intel iGPU and an Nvidia GPU)
The latest update to the kaktwoos app should ensure the tasks run on the correct device.
If you are a user with a multi-vendor host, please keep an eye on your results and let us know if you're having any issues.

As always, please get involved with the conversation in the message boards, and join the Discord!

ReCaptcha problem is also keeping people from signing up via the website. Workaround for people with this problem: add the project via BOINC Manager Add Project, this circumvents the captcha.


Disabled ReCaptcha for now. I'll be upgrading the server to 1.2.1 soon, hopefully today, which will fix a huge number of issues we keep discovering.

Frankly, I don’t fully understand why this is happening. The scheduler is set to 1 * NGPUs and it seems to be doing exactly that for several clients. Perhaps we just increase this value as a workaround, but in theory there shouldn’t be an issue as it is.

- You can remove forums you don't need from /html/ops/create_forums.php and then rerun the script.
- You don't have any spammers or trolls yet, but eventually, you will. So make people moderators. Preferably your own guys.
- If you don't want to use the forum rating, you can disable that. (set <no_forum_rating> in config.xml)
- In the future, when you don't want people without credit to post in the main forums, set that a minimum credit amount is required, or a minimum RAC. These people can then still post in the Help Desk forums.
- Adjust the description of the forums, now things are saying the default "BOINC".


- I was struggling with imagination when we bootstrapped these forums, so I'll consolidate them down and rethink the descriptions.
- I've set up a couple of our guys as moderators, I'll find a few more volunteers and encourage them to stay active. I know you're very active over on the BOINC boards, so I've granted you some access here also.
- I'll have to have a think about the credit thresholds for this, raised an issue for it in the meantime.
- Thanks for the ratings system suggestion, I'll implement that change. I've implemented that change.

We're just using the latest BOINC containers, I've been working on building my own today because they haven't cut a new version in 8 months.
I've been making manual patches to a bunch of bugs which were already fixed. I'm going to contact the container maintainer to see if he'd like to cut new versions and if they're looking for other maintainers.

The only failures I see for you are issues with the version 1.12 of the kaktwoos app. We've since resolved issues with fprintf and all current version results are valid as expected.

Thanks. Locking this thread

We've taken a few manual steps to reprioritize jobs which were created as a result of a computation error. This will be running as a 3 hourly task:

while read line; do
    if [[ "$(echo "${line}" | awk '{print $2}')" -lt 2 ]]; then
        mysql -D minecrafthome -s -N -e " \
            UPDATE result \
            SET priority = 1 \
            WHERE id = $(echo ${line} | awk '{print $1}')"
    fi
done <<< $(mysql -D minecrafthome -s -N -e " \
    SELECT id, COUNT(workunitid) \
    FROM result \
    WHERE server_state = 2 AND priority = 0 AND workunitid in \
        (SELECT * FROM \
             (SELECT workunitid \
              FROM result \
              GROUP by workunitid \
              HAVING COUNT(workunitid) > 2) \
         AS a) \
    GROUP BY workunitid;")

Post:
Finally, support for multiple GPUs and checkpointing has landed.

• If you have multiple GPUs, the research apps will now make use of all available GPUs.
• We now support Intel GPUs.
• If work is suspended, or your machine is powered off, checkpoints will now ensure work does not start from the beginning.
• You will also notice work estimates are far more accurate.
• You do not need to take any actions to enable these features.
• We are also taking steps to increase the priority of additional results added to workunits after computation errors. This in order to speed up validation of incomplete workunits.

Thank you to Hypprs, nicoboss, DutChen18, BalintCsala, and anyone else who was involved in testing and updating the app.

For the third time in 1 week, Minecraft@Home has broken the tallest cactus height record in normal terrain generation.

Congratulations to volunteer SirNapkin1334, your host was responsible for locating this one!

While I have your attention, user profiles are now enabled, please ensure you create a user profile.
This will ensure you can be selected for 'user of the day' which is displayed on the homepage.

Perhaps the issue is made worse by having 230,356 tasks already in the queue ready to send. With a pool that large, it may take many days for the resends to get issued.


Yeah, I'm still looking into this, I assume there's a solution without just reducing the pool size.
