DENIS@home

New v1.05 DENIS Application

We have launch recently the new 1.05 version of the CRLP2011EPI app.

With this version checkpoint seems to work correctly
and coupled with the new validator
all the platforms seems to give us equal results.

We encorage to crunchers to switch all to the new version of the app.

Il y aura Lundi 6 juin des Wu d' ATLAS dispo

"ATLAS@home: WU running out shortly - more on Monday 6th
Hi all, just a heads up that we will likely run out of WU in the next few hours. We should get some more back in the system on Monday.

VirtualLHC@home: CMS Jobs Available Again
There was a fault with a server at CERN last night, which meant that we could not submit new CMS jobs, so we ran out.

However, the problem has now been fixed and CMS jobs are available again. Many thanks to the staff who worked Saturday night and Sunday to fix the problem.

VirtualLHC@home: vlHC Theory Application 64bit upgrade
We have put the new Theory 64bit Application into production today.

Please note the following important changes:

As it is a 64bit application, you must have VT-x / AMD-V acceleration enabled:

- To check this, in your VirtualBox Manager select "Settings -> System -> Acceleration" and make sure that "Enable VT-x/AMD-V" is activated. Also make sure another hypervisor isn't installed or running like KVM or Hyper-V.

For volunteers with 32bit hardware, the legacy 32bit Theory Application will be retained for a while:

- (subject to CoPilot continuing to run on a best-effort basis, as our CoPilot support person has just left CERN).

The CoPilot job scheduler system has been replaced by Condor:

- This enables us to unify both Theory and the LHC experiment applications going forward. (Condor is already implemented in the CMS Application here).

SETI@home Beta Test: Arecibo still threatened with closure.
Recently the NSF announced its intent to start the process which could lead to the partial shutdown, mothballing, or complete disassebly of the Arecibo Observatory. As most of you know, this is not a new discussion in the scientific community. Several years ago we had asked you write letters to Congress in hopes of averting this fate.

A petition has been started on whitehouse.gov to ask the President to ensure it is funded. I'm pessimistic about the chances that it will change anything, as the President cannot change Congressional budget priorities, and only has limited ability to move money between NSF programs. However, bringing attention to the issues of science funding in this country cannot hurt.

Einstein@Home:
NOUVEAU TROU NOIR BINAIRE DETECTÉ ( LIGO )
LIGO Does It Again:
A Second Robust Binary Black Hole Coalescence Observed

The two LIGO gravitational wave detectors in Hanford Washington and Livingston Louisiana have caught a second robust signal from two black holes in their final orbits and then their coalescence into a single black hole. This event, dubbed GW151226, was seen on December 26th at 03:38:53 (in Universal Coordinated Time, also known as Greenwich Mean Time), near the end of LIGO's first observing period ("O1"), and was immediately nicknamed "the Boxing Day event".

In GW151226, the two black holes weighed in at 14 and 8 solar masses and merged at a distance of some 1.4 billion light years from Earth. Get all the info from the LIGO science summary .

Thanks for your continuous support in these exciting times!

Oliver, for the whole Einstein@Home team

CERN Summer Computing Challenge - SOFTWARE STOPPED
The software which supported the CERN Summer Computing Challenges in 2014 and 2015, and continued to run Theory jobs with minimum support, has now been halted due to lack of developer resources for this activity.

PLEASE DO NOT RUN CHALLENGE SOFTWARE UNTIL FURTHER NOTICE AS YOUR JOBS WILL BE LOST.

Many thanks to all Challenge volunteers who have contributed to this project and helped to explore new Web and CernVM technologies. We do have plans for a new WebAPI system for running multiple vLHC jobs inside a single multi-CPU VM and will announce this in due course.

LHCb Nouvelle APP

VirtualLHC@home: LHCb beta application published
A new application to simulate Beauty physics at the LHC from the LHCb experiment has now been made available for those accepting beta applications.

Like the CMS application and the 64-bit version of the Theory simulations app,
the Beauty simulations require a 64 bit computer with virtualization extensions (VT-x) enabled.

Please refer to the instructions in the box on VT-x on the page: http://lhcathome.web.cern.ch/join-us for more information.

Specific discussions on the Beauty simulations can be done in the forum thread dedicated to the LHCb application .

The team.

Quake-Catcher Network:

QCN Move To USC Complete - New Address is quakecatcher.net
The move to the University of Southern California is complete. Thanks to Stanford and CalTech Earth Sciences for hosting us over the years. QCN is now supported by IRIS (Incorporated Research Institutions for Seismology) and the SCEC (Southern California Earthquake Center) based at USC. You may want to "Remove Project" and then re-attach directly to our new BOINC project address http://quakecatcher.net

VirtualLHC@home:

Scheduler and vbox update to detect 64-bit enabled computers
The BOINC scheduler has been updated to detect 64 bit machines that do not have the virtualization hardware extensions enabled. Also vboxwrapper has been updated for better error handling, and vboxwrapper 26193 is now deployed for Windows and Linux for the Theory application. This setup has been tested in our dev project.

Similar updates will follow later for other applications.

Many thanks to Rom Walton for providing these changes to the BOINC code.

Many thanks to Rom Walton for providing these changes to the BOINC code.

Update: As a number of volunteers have reported issues with the latest Theory simulations vboxwrapper 26193, we have disabled this version for now.

The CMS and LHCb applications seem to run fine with the new wrapper.

ATTENTION Sierpinski Problem ESP/PSP/SoB (Sieve) PrimeGRID se Termine le 31 Juillet

PrimeGrid: ESP Sieve shutting down July 31st
The ESP-Sieve has reached its optimal sieving depth and will be shut down soon. If you're close to that next badge level, now is the time to get it. The actual date will be depend on when work runs out, but we will make sure there's work until at least the 31st.

ATLAS@home: ATLAS@home releases a beta application for the multi core jobs
We have released a beta application named "ATLAS_MCORE" for the ATLAS multi-core jobs.

If you are interested in testing it on your machine, you need to allow test task in your project preference to receive jobs from this new application.

This can be enabled by login to your account on the atlasathome webpage, then click on "Your account", then click on "ATLAS@Home preferences", then check the box next to "Run test applications".

The multi-core version will check the BOINC client for both the available CPU cores(the number of CPU cores the client is configured to give to BOINC to use) and available memory size(the number of memory size the client is configured to give to BOINC to use) to decide how many cores will be allocated to one virtual machine which runs the ATLAS job.

For the ATLAS multi-core job, the relation between memory size and number of CPU cores is defined in this formula:

Total_Memory=1300MB+1000MB*Number_of_CPU_Cores

For example, a 1 core job requires 2300 MB memory, and a 2 core job requires 3300 MB memory.

The number of CPU cores which will be allocated to the virtual machine is also calculated according to this formula.

Number_of_CPU_cores=(Total_Memory-1300MB)/1000MB

The minimum number between Number_of_CPU_cores and the available CPU cores from the client is used to allocate to the virtual machine.

Currently, this test app can utilize from 2 to 8 cores of the client depending on the available CPU cores and memory size from the client.

By using multi-core jobs, we expect the runtime of jobs is close to runtime_of_single_core_job/number_of_cores, and it can significantly saves the usage of memory for clients which offers multi-cores to BOINC.
