|
|
The CPU Project of the Month for March is actually three projects related to processing raw data for the Large Hadron Collider at CERN. The concept is to shrub any combination or all three during this month. Ivanst is our resident expert on these projects so I'll let him provide details on what they involve, but here are the basics.
LHC@Home / Sixtrack
http://lhcathomeclassic.cern.ch/sixtrack/
Virtual LHC@Home (Formerly Test4theory)
http://boinc01.cern.ch/vLHCathome/
Atlas@Home
http://atlasathome.cern.ch/ATLAS/
Here's a 4th project that isn't exporting stats/alpha phase/experimental? Shrub it if you can?
Beauty@LHC
http://lhcbathome.cern.ch/Beauty/
Virtual LHC and Atlas require Oracle's VM Virtual Box software. Don't be intimidated by that (as I was), it's easy to DL and install, but need to get the correct version from Boinc/Berkeley. When running those two projects the VM is transparent, doesn't require any tweaking that I can tell. |

It looks like you covered everything Landroid.
Atlas & LHC are actual collisions that are pending analysis, VirtualLHC are modeled collisions that are being considered for actual LHC runs.
With the new, bigger, more powerful LHC coming online there will be plenty of high profile work to do in the coming months.
The most controversial of which is the attempted creation of a miniature black hole!
Please reach out to me if you have any difficulty in getting the projects setup. I will gladly assist!

Can I help with the black hole? Miniature is fine, I will feed it and watch it grow!

Certainly Yankton, but be forewarned!
They say once you go black-hole you can never go back... _________________

Question from the rock gallery,
Do Atlas and Sixtrack support checkpoints? I really don't want to run huge units for nothing when i have to switch to other activities _________________

Be careful of where you stick your ram in ATLAS, she requires a large quantity _________________

LHC@Home / Sixtrack
This one is more popular that I realised - almost 30 Knights earned points in the last week. Average production is up 10%.
Tasks ready to send 189,204
Milestones:
DoW 2,500,000
GMC-Peeper of the Castle Anthrax 700,000
d_ino 300,000
The Holy Hand Grenade! 150,000
Sir Mifun Fat in a Right Place 150,000
Gemjunkie[TeaM] 50,000
Eric (Cholupa) 30,000
Brandon 10,000
Virtual LHC@Home
7 Knights shrubbed this in the past week. Production % is up significantly, but still only 3544. daily average.
Tasks ready to send 101
Milestones:
Walt V 5,000
Sir Clark 2,000
Atlas@Home
Ivanst needs help on this project; 8 more Knights are attached, but no one else crunched Atlas this week. (I'm DL'ing some now.)
Tasks ready to send 1,159

Ohhhhhhh Atlas has badges! Do the other CERN projects?
https://atlasphysathome.web.cern.ch/content/standard-model-badges
The LHC is restarting soon with much higher power. Crunching Atlas can help preparations.
Quote: | But how will physicist find the needle in the haystack, and recognise what is "new" when the LHC collider restarts in 2015 ?
Large scale simulation campaigns are a key ingredient for this. We have integrated and coded everything we know about the standard model of particle physics, about the ATLAS detector performance, about the proton beams expected properties, in large programs. We have extrapolated what "known physics should look like" when the machine turns on, and investigated in parallel what "new" phenomena predicted by alternative models of the universe, particles and interactions may look like... if such process exist. Nature will decide but, meanwhile, the preparation is already an exciting adventure we are sharing with you.

I prolly need some help with Atlas. It seems to be a monster memory hog. It's currently suspended, but 90% of my 12Gb is used. Was running 5 WUs on a I7 and noticed 2 more said "waiting for memory". Should I limit processing to 1 or 2 WUs? Of course I've forgotten how to to this.  |

I have a question for the penguin users in the room for this. I have installed boinc and a copy of VB on fedora 21 on a computer of mine but boinc refuses to recognize that i have installed virtual box in order to run Atlas or vLHC. It tells me "VirtualBox 3.2 or later is required" but I have a 4.3 version. Anyone know how to fix this? It runs other boinc projects just fine though. _________________

This sounds like an issue I was playing with last year. I'm assuming you have hardware that supports secure boot. The virtualbox driver needs to be signed which virtualbox can't do on linux. I did find a workaround for this, I will try and find it for you tomorrow if you don't beat me to it.
Basically it's a conflict with secure boot UEFI.

Thanks for the link Yankton, I appreciate it. through that link i found this which outlines steps to sign it without turning off secure boot http://gorka.eguileor.com/category/technology/linux/
the only problem is that I have created the key successfully but cannot get it to sign the driver. It says it cannot find the path or filename /usr/src/kernels/$(uname -r)/scripts/sign-file sha256 ./MOK.priv ./MOK.der $(modinfo -n vboxdrv) and i am not totally sure if i have messed up the command or not.
I am a linux noob, so please forgive my ignorance
EDIt: It cannot find this file because apparantly there is nothing in /usr/src/kernals/ ............... not sure why it is empty _________________

Plomos,
first try Code: | sudo yum install kernel-devel kernel-headers |
