    March again, as always at least two days earlier than you expected. What are we to do this month?
    First the still ongoing LHC Classic challenge, where NeoGen shows such a fine pace that he has climbed three places on the team ladder over the last few days.
    I had to cut one image file, so away with that of LHC, you've seen it for a month now...


    February 26 to March 05 - Hurrah for Prof Peter Higgs! LHC Classic Challenge
    The Scottish BOINC Team organizes a challenge in honour of the man with the most famous boson of all: Peter Higgs.

    March 01 to March 06 - Rosetta Flyby Challenge
    BOINCStats may be starting a new classic, now Simap has folded.

    March 04 to March 08 - Julius Fromm Memorial Race
    ngb:setiteam wants to honour Julius Fromm, a chemist and inventor of a process for making condoms from liquified rubber, by organizing this memorial race.
    The connection with extra-terrestrial intelligence is obvious, but I leave it to your imagination and/or dirty mind.

    March 06 to March 13 - Binary Cyclops Challenge
    If we write 27 in binary:
    11011
    and compare with 2015 (the current year in the usual calendar) in binary:
    11111011111
    we see that both have only one zero, one eye, and that this eye is right in the middle, making each number a palindrome.
    According to OEIS A129868, these symmetrical monsters are called binary cyclops numbers. More about the 27121 prime search can be found here.
    News and infos about the PRPNet client can be found here.
    To take part, you have to activate the following lines in prpclient.ini: server=27:100:1:prpnet.primegrid.com:12006
    Stats will be available at the well known place here.
    Chatter is to be found here.


    March 10 to March 14 - CRUNCHATHLON WCG [MONTHLY RUN - RACE IV]
    This challenge issued by the french team CRUNCHERS SANS FRONTIERES will take place every month at varying dates for four days. All teams are welcome Let us take forward the World Community Grid project! And those OET WUs are sure hard to get.....42 of our members were active at the start of this challenge, can we get to 50 and pass the Alliance of French-speaking Crunchers? Can we even try to challenge SETI. Germany? They want to be...but then we have to pass BOINC@Poland and Ukraine first!

    March 15 to March 20 - Need For Speed II - NFS Challenge
    SETI.USA comes with a 2nd edition of the "Need for Speed" challenge (remember the first? June 2014)
    kle got off with a rocket-start, but it seems to be on his weekend-only box, and he has now slacked off so I could get past him.

    March 15 to March 20 - Solar Eclipse Challenge
    From March 15th 07:41:00 UTC until March 20th 07:41:00 UTC we -PrimeGrid- will have a 5 day challenge running SR5.
    As seen from the Earth, a solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks ("occults") the Sun. This can happen only at new moon, when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses only part of the Sun is obscured. An eclipse is a natural phenomenon. Nevertheless, in some ancient and modern cultures, solar eclipses have been attributed to supernatural causes or regarded as bad omens. A total solar eclipse can be frightening to people who are unaware of its astronomical explanation, as the Sun seems to disappear during the day and the sky darkens in a matter of minutes. To celebrate this phenomenon, we are hosting a 5 day challenge on the SR5 subproject.
    This project is an extension of the original Sierpinski/Riesel problems (SoB/TRP). It is attempting to solve the Sierpinski/Riesel problems for base 5 by determining the smallest Sierpinski/Riesel numbers. Therefore, primes of the form k*5^n+/-1 are being sought for even k's. A distributed effort is currently ongoing in support of the project. More information can be found in the mersenneforum.org Sierpinski/Riesel Base 5 thread.
    To participate in the Challenge, please select only the SR5 (LLR) project in your PrimeGrid preferences section. The challenge will begin March 15th 2015, 07:41 UTC and end March 20th 2015, 07:41 UTC. Application builds are available for Linux , Windows and MacIntel 32 bit and 64 bit. Intel CPU's with AVX and FMA capabilities will be significantly faster than the ones without, as this instruction set allows for more computing power. ATTENTION: The primality program LLR is CPU intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your computer. WU's will take about 2.5 hours on fast/newer computers and 5+ hours on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR. Restricted airflow is one of the primary reasons for overheating. Take the time to monitor the fans and review the dust buildup. Please, please, please make sure your machines are up to the task. NOTE: Should you be lucky enough to find a prime, extra processing is required and the run-time may be as much as 10 times longer than normal. DON'T ABORT TASKS THAT SEEM TO BE TAKING AN UNUSUALLY LONG TIME TO RUN!

    March 17 to March 21 - CRUNCHATHLON GPUGRID [MONTHLY RUN - RACE VII]
    This challenge issued by the french team CRUNCHERS SANS FRONTIERES will take place every month at varying dates for four days. All teams are welcome Let us take forward the GPUGRID.net project!

    March 24 to March 31 - B@P POTM
    There's cryptic and there's cryptic, but this one is very cryptic indeed. BOINC@Poland (B@P) organizes an Einstein@Home challenge, which is their Project of the Month (POTM).

    It might be all to the good actually. Samsung could provide AMD with the much needed R&D budget.
    And AMD could provide Samsung with 64-bit ARM based products to aid Samsung against nVidia's Tegra.
