Problems with several camb_boinc2docker tasks:

These downloaded in a flood, probably due to a severe underestimate of runtimes (initially about 5 minutes).

Each was shown needing 10 virtual CPU cores. They started actually using 3 virtual CPU cores, leaving 7 more idle. Then, they stopped using even those three, even though it kept them reserved.

By the time the progress reached 0.100% after a few minutes, the estimated remaining time was over 4 days.

After 28 minutes elapsed, the estimated remaining time was over 19 days, with progress still at 0.100%. Then the tasks went into Computation error.

These tasks appear to be trying to have the VM simulate multiple cores at once, something I haven't seen before. Are there restrictions on which versions of the VM has this feature?

Robert,

I did renew the Virtual Box - VirtualBox 5.1.14 Oracle VM VirtualBox Extension Pack

and this i get as answer


Runtime error opening 'C:\ProgramData\BOINC\slots\4\boinc_9381c7883981d9c5\boinc_9381c7883981d9c5.vbox' for reading: -103(Path not found.).

[snip]

Raimond,

Did you install a new version of VirtualBox, or only add a version of the extension pack which may or may not have the same version as the VirtualBox previously installed?

Only VirtualBox appears to be needed here. If both are installed, they MUST have matching version numbers unless you want problems.

In case you don't know where to look for new versions of VirtualBox, start here:

VirtualBox

I found that the versions with version numbers staring with 5.0 cause problems with Cosmology@Home tasks; but those with version numbers starting with 5.1 do not.

With which version of VirtualBox? I had a similar problem with an older version, and had to install a newer version to fix it.

Some BOINC projects give the normal amount of credit to tasks returned late if the quota for that workunit was not already met. This tends to prevent most credit problems if the server was offline for a while. Have you considered setting up for that?

I hadn't really been running into this issue up until somewhat recently on some of the computers I use,however doing a quick check on a system that recently has been throwing this error on almost every VM workunit or "VM job unmanageable" shows some insights:

00:00:01.829767 SSM: File header: Format 2.0, VirtualBox Version 5.0.18 r106667, 64-bit host, cbGCPhys=8, cbGCPtr=8

[snip]

The line I quoted shows you were running the same version of VirtualBox that gave problems for me.

Upgrading VirtualBox to version 5.1.12 fixed that problem for me.

Since writing the above, I shut down BOINC and installed VirtualBox 5.1.12, then restarted Windows 10 and BOINC. This MAY have fixed the problem for the other BOINC project with VM tasks, but it will take weeks to be sure. No Cosmology@HOME tasks have restarted yet, so there's no information on whether this is also a fix for them.

A problem with my camb_boinc2docker 2.04 (vbox_mt) tasks:

Each arrives in state Ready to start (7 CPUs)

Every time one starts running, it runs a little over 10 minutes, then goes into a state of:

Postponed: VM Hypervisor failed to enter an online state in a timely fashion.

No checkpoint was written first. Windows 10 requires fairly frequent reboots for updates, and after every such reboot, the elapsed time drops to zero.

The only other BOINC project I subscribe to that has VM workunits is showing the same problem.

Initial runtime estimate is 00:06:05, the remaining time estimate after this happens is 00:02:21.

I don't think I've ever had any successful VM tasks before, so could anyone suggest what could be the problem?

The normal ways of checking the version number don't work with VirtualBox, so is another way available?

I've had to set No new tasks on one of my computers - the recent camb_legacy tasks demand so much memory that they cause problems running programs from the console. Where can I find information on the memory and virtualization requirements of the other applications so I can decide whether to switch that computer to running only the other applications?

Could you mention the approximate amount of memory this new app requires, relative to the previous app, so users who have had to set No new tasks due to the memory demands of the previous app can decide whether to enable ONLY the new app?

I've seen a VM problem you might want to watch for. Some of the older methods of detecting VM support will run only once per computer, so if that computer had it run before VM support was turned on in the BIOS or UEFI, that computer will never check for VM support again; instead, it will only remember the failure. Have you found a way to force a new check for VM support even while BOINC remembers a failure from a previous check?

Another problem on one of my computers - it is already supplied maximum memory compatible memory for the motherboard (8 GB), but VirtualBox requires so much memory (4 GB) that it cannot run more than one VM workunit at once, and even one leaves too little free memory to allow a reasonable selection of other BOINC projects to use the remaining CPU cores. Also, Windows Vista has rather poor memory usage for 32-bit applications (about as much memory required for the SYSWOW64 modules needed to allow 32-bit programs as for the programs themselves), so I can no longer use the console while your legacy application runs - it's still more memory hungry than nearly all applications for other BOINC projects I am interested in. Therefore, Cosmology@Home is set to No new tasks on that computer, and will stay that way unless you offer a way to select only applications that are less memory-hungry under Windows Vista. (When I get past my current reason for keeping Windows Vista, I expect to be more likely to replace the entire computer than to replace just the Windows version.)
