1) Message boards : News : do you have any experience with running a VM based application in BOINC? (Message 46992)
Posted 12 days ago by Profile robertmiles
Two years ago I did some crunching on VM without problems until I decided upgrade to a newer version of VM. Probably I did a mistake in the process and since then it has been impossible to install VM as always a missing archive is reported. I found others users of VM with the same problem and tips of how to fix it, but in my case it didn't work.

Did you try uninstalling VirtualBox, restarting, then installing it again? That often helps with missing file problems.

The second GTX 750 Ti gave the same problem. I've since found that the problem is actually with the motherboard, a Pegatron IPISB-CH2. That model of motherboard is known for having problems booting properly when using any Nvidia-based graphics board with a GPU of a generation more recent than the Fermi generation. It also has problems using the more recent AMD GPUs. I've decided not to use that computer for GPUGRID any more.

My newest computer, with a GTX 980, is now trying to get a GPUGRID task; none seem to be available now.

Several warnings if I try to update the preferences for my new computer:

Warning: Creating default object from empty value in /home/ps3grid/projects/PS3GRID/html/inc/prefs_util.inc on line 218

Warning: Creating default object from empty value in /home/ps3grid/projects/PS3GRID/html/inc/prefs_util.inc on line 218

Warning: Creating default object from empty value in /home/ps3grid/projects/PS3GRID/html/inc/prefs_util.inc on line 218
Primary (default) preferences (Switch View)

Warning: Creating default object from empty value in /home/ps3grid/projects/PS3GRID/html/project/project_specific_prefs.inc on line 239

Do I need to do anything about these warnings?

Something you may want to consider if you decide to create more badges:

There is an unusual amino acid called BMAA. Normally found only in blue-green algae, in cyanobacteria, in cycads, and in the brains of Alzheimer's victims. Not essential.

It may be relevant that there is a program called swan that converts CUDA source to OpenCL source.

Some, as a user only.

I found that you first need to enable VM, usually early in the boot process where you are still talking to to the BIOS or UEFI, and have not yet told it which operating system to boot (even if you only have one operating system installed). Details of how are often specific to the model of computer you have.

If you have ever tried to download a VM workunit before, you must then edit a BOINC file which records that no usable VM was found for the previous VM workunit. Retrying this check is NOT automatic for BOINC 7.6.33 and earlier; this may change for future versions. This change needs to be done while BOINC is not running.

At least one of the BOINC projects I get VM workunits from is not compatible with the 5.0.* versions of VirtualBox, so you must now upgrade to one of the recent 5.1.* versions if you're interested in that project. Restart or reboot after this upgrade.

Now start BOINC, and tell at least one BOINC project that it is allowed to send you VM workunits.

I'm a fresh newbie in gpugrid and cannot get any work since first attempted yesterday.

My WCG is working fine on CPU since 2008.


With what graphics card? GPUGRID insists on fast, fairly recent graphics cards with an Nvidia GPU, and has very few CPU-only workunits.

I've also been on WCG since 2008.

Many others are also complaining about getting little or no GPUGRID work now.

I'm getting new WUs, but with VERY slow downloads of the larger files.

I'm getting tasks on my laptop, my desktop won't get them though. It might have t do with its wifi signal because WGC does the same thing. I'll try using my laptop as an access point.

If you use BOINC Manager (Advanced View) on your desktop, click on Activity, then make sure you do not have it set to Suspend network activity or Suspend GPU or Suspend. Also click on Projects, then GPUGRID, and make sure you do not have it set to No new tasks (listed in the Status column).

If you use Simple View, click on View, then Advanced View, to switch views. To switch it back, click on View, then Simple View.

Also click on Projects, then on one of the BOINC projects listed, then Home page. You should then see a web page for that project.

By the way, what GPU (or graphics card) does that desktop use? GPUGRID can use only some of the graphics card models.

The forwarding services already available, such as gridrepublic and World Community Grid, only need to download one copy of the files specific to each workunit, regardless of how many wingmates tasks for that workunit will be sent to. So such forwarding already provides some server relief, just not as much as you want.

World Community Grid, however, requires a code review for all applications they forward; I'm not sure if you'll consider that fast enough to be worthwhile.
