Apologies. There was an issue with how the job was setup, which resulted in many computational errors. The job was suspended while we fix the problems.


I see we have new tasks to crunch, and they are still requiring up to 6gb per task. Insanity. I thought this was going to be fixed?


One of our scientists is trying to submit a job with a couple of problems. We have decided to move his task to a resource with higher computing power. Unfortunately, this will probably mean that volunteers will not have a job to crunch on.


Would not be easier to change project settings to stop feeding WUs to users with not enough RAM?

Exactly same problem as mine was reported already

https://mindmodeling.org//forum_thread.php?id=1131


Could this be investigated, please?

I had run one WU run for slightly over 2 hours. Task seems to stuck at 9% so I suspended all work and re-enabled it straight away. WU finished within 7 seconds and reported as valid. CPU runtime was zero.

I had another task that had run for hours and eventually was reported as valid with similar runtime.

I am seeing tasks using almost 6 gb of RAM each. Is that intentional? Most machines will choke on that.


I had a few tasks that were ok. Now I am stuck with one that is waiting for memory.
I guess I am out for now until I will be able to add some more RAM to my aging host.

I am trying to make sure all questions are being answered along with updating everyone on conditions that may propose a problem to volunteers. I am still trying to filter through posts that are not related to MindModeling - thank you for letting me know that this is an issue.


No problem at all. Glad to see new work being distributed again.

Good morning!

As I take over for Josh, please bear with me. I am aware there are currently some issues out there. I will do my best to to support you all and this project.

I look forward to working with you all.

Best,
Olivia


Are you actively monitor forum, Olivia? There are some spammy posts that should be removed.

I get SIGSEGV: segmentation violation error when I try to run project in VirtualBox with latest Debian as guest OS. Another project runs just fine.

Any ideas?

Must have posted without noticing your post.
Making those changes in grub file solved the problem. Thanks.

I run memtest86 to check RAM but everything is good. Host system (Windows 10 Pro) is working ok and I run other projects just fine.

Any ideas?

Posted 22 Feb 2020 by Hal Bregg
I'm glad to see project is live again. I started BOINC journey with this project but hadn't had much chance to contribute to this project.

I would focus on project and steady flow of WU and not worry about badges if I were you. For example Einstein and LHC don't have badges, yet, it doesn't stop user to crunch for those projects.

Hello,

I haven't seen any new Wus in months. Is it due to lack of interest from reaserchers or dificulties in creating new projects?

Hello,

It hasn't been resolved. It can be solved as Woodles suggested, but it would be nice to have it sorted once for good.

Just a quick update on my previous topic. I had some other projects recently, ending up with computational errors. I think it could be something to do with the hardware (memory or PSU perhaps) which I am looking for to upgrade soon.

If you think this was caused by something else, feel free to let me know.

Hi Brandon,

It is 64 bit with only 3GB of RAM at the moment.
