Things change fast in the IT world. Once I botched a possible career in IBM by saying that I wanted to use UNIX. Nah, they said, that is only for students...

Real IBM programmers write in PL/I (Complex ones also).

Posted 23 Apr 2010 by dulcimoo
From my understanding we are helping them \\\"tune\\\" the magnets and such [via simulation] so that the LHC can do more work faster and they have less time \\\"tuning\\\" to make things work well.

We are an operations utility rather than a research adjunct.

The work is important, but not core research.

The fact that the LHC has started to return results so soon after the restart shows that what we do works!

I don\'t think LHC@home is going to process any actual data. If the beams are not running as expected or they need to tune a mag or something perhaps, but all the science data is going to be dealt with on site.
5) Message boards : LHC@home Science : LHC@home - Out of Tasks? (Message 20969)
Posted 13 Jan 2009 by dulcimoo
The tasks are very \"bursty\". The have them in bunches, so if you only look every few days you could miss them. When you do manage to get one, make it the top priority to get processed - they only credit 60% of the WU distributed, the rest are redundant and get no credits.

Posted 22 Dec 2008 by dulcimoo
They don\'t send tasks often. Right now there are a few tasks left, just over 1000. Be quick or wait until next time. I hope you get some tasty tasks. Umm.

I have the priority of LHC set 10:1 over any other project. It seems to help.

I just got a few tasks for my Mac virtual windows 2K system.

9) Message boards : Cafe LHC : Q: LHC vs Cosmic Rays (Message 20344)
Posted 14 Sep 2008 by dulcimoo
One of the arguments for the LHC not killing us all is that Cosmic rays have already done this \\\\\\\"experiment\\\\\\\" and have created blackholes and we are still here.

So here is my question: In terms of energy how powerful are Cosmic rays in relationship to the LHC? Same Power, 5X more powerful, 100X, whatever. If someone could answer this so I can add so numbers to my arguments I would appreciate it.

Thank you in advance...

... I have some numberson the cosmic ray side which might help ... \\\\\\\"[ultra high energy cosmic rays] They are 100 million times more energetic than anything produced by particle smashers on Earth.\\\\\\\" and \\\\\\\"Ultrahigh-energy cosmic rays are considered to be those above about 1 billion billion electron volts (1 times 10 to the 18th power).

The most energetic cosmic ray ever found was detected over Utah in 1991 and carried an energy of 300 billion billion electron volts (3 times 10 to the 20th power).\\\\\\\" http://www.eurekalert.org/pub_releases/2008-03/uou-rcr032008.php

Another site quotes: \\\\\\\"Most galactic cosmic rays have energies between 100 MeV ... and 10 GeV (corresponding to 99.6% of the speed of light). The number of cosmic rays with energies beyond 1 GeV decreases by about a factor of 50 for every factor of 10 increase in energy. Over a wide energy range the number of particles per m2 per steradian per second with energy greater than E (measured in GeV) is given approximately by N(>E) = k(E + 1)-a, where k ~ 5000 per m2 per steradian per second and a ~1.6. The highest energy cosmic rays measured to date have had more than 1020 eV, equivalent to the kinetic energy of a baseball traveling at approximately 100 mph!\\\\\\\" http://www.srl.caltech.edu/personnel/dick/cos_encyc.html

So how does this range of 10^10eV - 10^20eV compare with LHC collisions at full power?

Posted 14 Sep 2008 by dulcimoo
I run windows 2000 under parallels and it works quite well. You could run linux under parallels if you wanted and perhaps get better performance. I installed parallels because I needed it for another application, but for LHC but it works well. XP is probably the best OS for parallels but I had an old copy of W2K so it was the most expedient option for me.

I run parallels in \\\"coherence\\\" mode which give me access to the windows applications and mac desktop at the same time.

My virtual windows system has been in operation since 15 Aug 08 and has processed 320 units of work.

Theoretical, its all that it is. We don`t know much its all about theories, calculated from observations and theories from many scientific minds.
In this case we can`t afford to be wrong,... anyone?

Well given that Cosmic Rays have more energy and we are still here ... I would not worry. And if some \\\"strange\\\" things happen and the earth is destroyed well \\\"It\\\'s been fun!\\\"

I believe that governments all over the world should increase their actual funds in Education to something like 90% of Anual Budget, and then perhaps less people would be saying things like this. Nonsense!!

In the US most of the budget goes to \\\"entitlement\\\" programs ... Social Security, Welfare, and the like. Increasing funding to 90% of the budget would not do much except make for some really fat cat school board members.

Yes increasing funding by some amount, say 2X-3X of current levels would do some good. 90% of the federal budget for education is just asking for waste and fraud.

I needed the emulated windows client to run SYSTRAN sp I didn't do it JUST for LHC but as long as I had it ... No work units yet however.

18) Message boards : LHC@home Science : LHC Countdown?? (Message 19715)
Posted 12 Jun 2008 by dulcimoo
I don't think so - taken from that website:

A clarification

The countdown timer was set to the 15th of May because there was no definite time given for the actual activation, recent events show that CERN wont be dividing by zero until much later on in the year, so now the countdown timer will be reset again and will be continually tweaked to go by the latest info that CERN are releasing.

So sorry to disappoint you all, but you wont be dying tomorrow.

What's up with this?


Is it a true countdown?

After millenia of religious fighting...
"We found [the] God [particle]!"

In this case I don' think the []'s can be used; well they can't be used without more context.

"After millenia of religious fighting ... we found G-d" is not quite the same as "After millenia of religious fighting we found the G-d particle".

Because the first part is not quoted at all ... it may be assumed that it could be a different person saying that.

Stationary vs. Non-Stationary "quantum" black holes. It seems to me the experiment has probably already been done by Nature. In the billions of years the earth has been around you would have expected two cosmic rays to impact each other with a vector velocity that would allow the capture of the produced partials and or black hole by the gravitational field of the Earth. Just my 0.02 euro.
