Not sure if this is normal. It has been four days of running ATLAS@Home with nothing to send back to you fine folks. rosetta@home and SETI@home never had this problem.

I just downloaded and installed a copy of Virtual Box from their site since I noticed out of the three @home's I participate in, this is the only one that talks about using Oracle's VB. That is all the troubleshooting I have tried so far.

Let me know if more info is needed. Thank you in advance.

All the best,
Rob

I have been running BIONIC for a couple of years with milkyway@home and cosmology@home running fine.
I recently started atlas@home with VM installed. I've noticed the program running slower and slower as it gets nearer completion with the last few 'seconds' taking hours to complete. The computation has been running now for 100 hours and it says its 100% completed which it has said for the last 25hrs. It just keeps running and will not send the completed program. Deadline date in 27 Dec 2014.
It says it using 3.42GB HD mem with 12.26GB available for BIONIC.

I guess it's difficult to predict how much time / percentage is required for a job to complete, most software installers have the same problem... B.t.w. this is related to a fundamental problem in computation: you can simply never know for sure a program will ever stop, it's called the Halting Problem. More to the point check if anything is 'moving' inside the VM image, after your patience has run out you may want to recycle the job.

Just looked again at the Atlas@Home task. It has run for 120hrs and is running now. The VM Manager says it is running but no movement in the preview window (How do you see the full image?). Cosmology & Milkyway tasks have been completed regularly as normal. The tasks are sharing 1/3 each of computing time.
It's saying 100% completed, deadline 27-12-14. Do I abort now?

Yeah I'm having the problem as well. I have four Atlas@Home tasks running. They are all at 100%, three of the tasks were running just off my CPU while the fourth was running off the GPU as well.

If they aren't taking the data is there even a reason for me to run it?

Hi,

Check if you have HyperV installed and uninstall it.

Same issue as "Communication with VM Hypervisor failed". VirtualBox tries to start up the 64Bit VMs, but fails. Boinc shows it as running, but behind the scenes, it has never been started.

If you need both on your Machine, you can introduce a "switch" to temporary disable Hyper-V to run VirtualBox VMs.

Win 7 x64

I have the same problem. I'm with Windows 7 and I don't have Hyper V. What can I do ?

Those tasks take less than 2 hours for me, so if they don't finish in 4+ hours, they probably didn't started at all. It is hard to tell what is the reason exactly without checking log files. My task were at 40+ before I realized that.

I did 3 things:
- enabled cpu virtualization technology in bios,
- installed Oracle VM VirtualBox 4.3.26,
- installed Oracle VM VirtualBox Extension Pack.

They finish after 1:40 now, even though Boinc says they still got 7+ hours remaining. I guess Boinc still remember they took 40 hours once. This estimated time is going down with every completed task though.

Other thing worth noting is that those task take about 2,5GB memory. If you run too many in the same time, you will end up using swap file and greatly reduce the performance.

I too was running in the same problem, my ATLAS task were almost 120 hours in and stuck at 100%, so i followed your advice.

I went to the BIOS just to check if CPU virtualization is ON or OFF and guess what it has been OFF for all this time, so turned it ON went to BOINC, deleted all ATLAS task's, reset the project and started fresh and now its running like butter.

For the memory problem, a fellow member suggested this and it works.

Create a app_config.xml file in the ATLAS folder located in C:\ProgramData\BOINC\projects\atlasathome.cern.ch and paste the lines below.
Each ATLAS task uses 2GB Memory, so adjust the max_concurrent according to your needs.

<app_config>
<app>
<name>ATLAS</name>
<max_concurrent>5</max_concurrent>
</app>
</app_config>
