WRT the new 'Download BOINC + Virtualbox' option, what version of Virtual Box is included, is it user configurable and is it a C:\ only install or can this be installed on another drive?

Oracle VirtualBox v4.2.16 is included in the BOINC v7.2.28 bundled installer, and I've already mentioned to them that they should include the version info on the BOINC download page. Also, I believe it's set up so that, if you already have that version (or a higher version) of VirtualBox installed, then the bundled installer will not try to install over it. Also, if the bundle does install VirtualBox, you cannot make any install choices, as it is a silent install. So VirtualBox is installed to the default location.

That's probably fine for most people, but if you wanted to install it to a different location, or customize any installation options, you'd have to go to the Oracle VirtualBox page and download their non-bundled installer: https://www.virtualbox.org/

Good luck!
Jacob

I thought VBox 4.2.16 was the bugged version? If so, why is it now available with BOINC 7.2.28? I am under the impression Vbox 4.3.? fixes the bug that has been causing grief for Rom's vboxwrapper and expected to see 4.3.? bundled with 7.2.28. Is 4.2.16 a typo here or am I confused, again.

4.2.16 is fine.
4.2.18 and 4.3.0 have bugs that affect T4T and probably RNA World.
4.3.2 has a bug that affects T4T but does not affect RNA World.

See here for details:
http://lhcathome2.cern.ch/test4theory/forum_thread.php?id=1364&postid=15560#15560
(I have done extensive research into all of these, and have filed bugs with Oracle.)

Because 4.3.2 has a known bug, and because the last version to work clean on all projects was 4.2.16, BOINC developers intentionally shipped with 4.2.16.

If you don't want to do any manual intervention, and you want to ensure your tasks complete without problems, stick with 4.2.16 until Oracle resolves Ticket #12291 (which affects 4.3.2)
https://www.virtualbox.org/ticket/12291

If you want to run 4.3.2 while also running T4T, then you should run T4T anonymous, using vboxwrapper 26033 or better, as the executable. See:
http://boinc.berkeley.edu/wiki/Anonymous_platform
http://boinc.berkeley.edu/dl/?C=M;O=D

Good luck!

You're welcome!

It's a bit of a chore to keep track of all these Oracle bugs, especially in the middle of a BOINC release, but we nailed it. The BOINC release itself is in very good shape, and I'm quite proud of our efforts.

Oracle still has 1 more bug to knock out.

Ironically, if T4T wanted to make 4.3.2 work for them, they could. They'd have to upgrade to the very latest vboxwrapper (I helped Rom put in a showstopping fix yesterday). T4T is thinking about doing that over the upcoming weeks. But without Oracle fixing the bug or T4T moving to the new wrapper, though, the user's choices for bug-free operation are to either stick with 4.2.16, or go anonymous platform with T4T and use the latest vboxwrapper manually along with any vbox version including 4.3.2.

Ok im very interested how the new shedulersystem can handle POEM ;)

Didnt see any changes in the GUI, so it seems there are only but important codechanges.

And well you should be. Between BOINC, T4T and Oracle there has been in the past a huge resistance to change. A few tried to make things roll with marginal to fair success. Then you came along and pushed the right buttons. Congrats, keep up the good work, wish I was young and had your energy again.

If you like projects that attempt innovative (radical?) approaches you might have a look at Volpex@UH . Rather than sending numerous tasks to discrete hosts they're organizing hosts into ad hoc workgroups that work in parallel on a single task. When the task is complete the workgroup dissolves. The Volpex team claims it has some major benefits for certain types of compute tasks but obviously their workgroup concept is not easily realized within the traditional BOINC framework, in fact it's bloody clumsy. It needs additions to client and server to work well. To that end I think they could use someone with your talent.

And that is more off-topic than anyone should go so I'll end it here.

@dskagcommunity: Yeah, the UI hasn't really changed, but the task scheduler has a couple fixes for bugs that would leave GPUs idle sometimes, and the work fetch scheduler has fixes (especially for anyone using GPU exclusions) including a better implementation that should further minimize RPC network calls to the projects, while better honoring user resource share preferences (especially when contributing to both CPU and GPU projects at the same time).

@Dagorath: Thanks for the kind words. I'm not as young as you think (33), I just happen to have a huge passion toward making BOINC work better! I used to run distributed.net before I switched to BOINC, I've investigated Folding@Home (when I was trying to find something that would work on my GTS 240 video card; it now runs Albert/Einstein/Seti/SetiBeta). I'll have to take a peek at Volpex -- thanks for mentioning it.

BOINC 7.2.31 is now the recommended version. The only change since .28 was to suppress image display as part of notices. This was to correct an issue with one particular project where the images cause the manager to crash.
