There is a climateathome project I just enrolled in it to see if it is worth doing. As for Test4Theory@home of CERN you need to have a Virtual Box installed and a recent version of BOINC. Mine are Virtual Box 4.3.6 and BOINC 7.2.41 on my Linux box.

The problem with Linux is that every distribution is different from the others, there is not a Standard Linux distro. For example, SuSE does not include the latest BOINC client in its distro, and this forces me to use 6.10.58. But this allows me to use the latest 4.3.6 Virtual Box release in Test4Theoy@home, while Window users are limited to 4.2.16. You pays your money and you takes your choice.

I am using a 32-bit Linux OS and CPDN runs OK, as do SETI@home, Einstein@home, Albert@home and LHC@home, plus Test4Theory@home, which requires a Virtual Box installation, always 32-bit. Instead. QMC@home insists in sending me a 64-bit app, which crashes immediately. I have tried to contact the Herr Professor who is the chief scientist (they have no message boards) and received no answer.

Edit. My CPU is a 64-bit AMD Opteron 1210, this is probably why QMC sends me a 64-bit app.

I am still using BOINC 6.10,58 on 6 BOINC projects, including Test4Theory@home which requires a 7.x.y client to run its latest version, but they are still maintaining the old version for those unwilling or unable to update their BOINC client. The result is that I am able to use Virtual Box 4.2.18 while the BOINC 7.x.y users must stop at VBox 4.2.16. So upgrading BOINC is a mixed blessing.

I finished one hadcm3n task on my Linux box and started another. Show graphics shows an Earth in a transparent window but it is stable. My Linux is SuSE 12.1 on this box, SuSE 12.3 on another running Test4Theory@home with VirtualBox 4.2.18.I had trouble running hadcm3n tasks while VirtualBox and T4T were running on this box, and selected the HADAM3P models. But since they are not available I got one hadcm3n task, finished it and started another.

Thanks Les. Anyway, I am running a hadcm3n model alongside 2 Astropulse units from SETI@home and a Gravitation unit from Albert@home, which is a Beta project of Einstein@home. This on my Sun WS of 2008 vintage, while I have confined my Test4Theory@home, SETI@home and Einstein@home on my newer HP laptop. All this on Linux, obviously. I am also running Virtual Box 4.2.18 on the HP. which is needed by Test4Theory@home, But in this moment I am mostly struck by the tragedy of Philippines Islands. We have many Filipinos in Italy and they are honest, hardworking people, always on the cell phone talking to their relatives at home.

I can see an Earth on my Linux box, but the graphic window seems to be transparent, contrarily to what happens at Einstein@home on another Linux box.
Maybe the window's parameters are not set right.

I am running 6 BOINC projects, including Test4Theory@home, which runs CERN jobs inside a BOINC_VM window and requires a connection to a server every time a CERN job is completed and a new one is needed, inside the same BOINC unit. So I am connected 24/7.

Yes, cool, but it works only fot VirtualBox 4.2.16 and not 4.2.18, for reasons unknown.

At Test4Theory@home, which uses a BOINC_VM Virtual Machine created by CERN, the second version of the wrapper takes a snapshot every ten minutes. But you must have at least a 7.0.x version of the BOINC client to receive this wrapper. Since I am still using BOINC 6.10.58 on my Linux box with SuSE Linux 12.3, I am still using the old wrapper.
Tullio
This works with VirtualBox up to 4.2.16, does not so far with 4.2.18, which I am instead using.
