21) Message boards : ATLAS application : Tasks download 1.9 GB EVNT files (Message 45478) Posted 20 Oct 2021 by tullio Post: I have downloaded two 1.9 GB Atlas tasks. Completed and validated. Max disk usage 4.04 GB. Tullio
22) Message boards : CMS Application : New Version v60.00 (Message 45432) Posted 15 Oct 2021 by tullio Post: No, but I am glad to see something working on my PC. Recently I had to stop my ccoperation with QuChemPedIA@home because of a problem with security certificates, as outlined by Dave Anderson on the BOINC home page. I wrote them that I have 4 projects working on Windows and VirtualBox. I am glad that LHC@home has no such problem Tullio
23) Message boards : CMS Application : New Version v60.00 (Message 45428) Posted 14 Oct 2021 by tullio Post: After years of trying, I finally completed and validated a CMS task on my Windows 10 PC. Congratulations! Tullio
24) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45420) Posted 4 Oct 2021 by tullio Post: On QuChemPredAI@home, which is a Linux project, most Windows tasks with VirtuaBox are faster than their Linux wingmen on my Intel i5 9400F. But a problem with Windows certificates is blocking all Windows uploads, so I have switched to an old Linux laptop with an AMD E-450 CPU, vintage 2014. Tullio
25) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45417) Posted 3 Oct 2021 by tullio Post: CMS is the only CERN program which does not run on my Windows PCs. It stops saying that Condor exited after about ten thousand seconds.I have been running Test4Theory@home since its begining. I was invited by Ben Segal to take part in the Alpha version in Linux.

26) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45415) Posted 2 Oct 2021 by tullio Post: In 1969, when I was working as a physics and astronomy at Mondadori Edizioni Scientifiche in Milano, I inteviewed Bruno Coppi at the International Center for Theoretical Physics in Trieste, later named for Abdus Salam.. A colleague of mine at Mondadori had a brother working at the Joint European Torus in Culham, UK.This is still doing research in spite of Brexit..I know that an Italian lady ls leading fusion rresearch at Fermilab in Chicago.

27) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45413) Posted 1 Oct 2021 by tullio Post: I know that a divertor is being built in the Frascati laboratory of the Istituto Nazionale di Fisica Nucleare. Frascati built the first Intersecting Storage Ring, ADA, designed by an Austrian physicist, Bruno Touschek and also gravitational wave detectors at cryogenic temperatures of the resonant mass type. The Tokamaks face big engineering problems, not only plasma physics issues. Tullio
28) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45411) Posted 30 Sep 2021 by tullio Post: The biggest fusion experiment is ITER being built in France. It should give the first plasma in 2025. Commonwealth Fusion Systems says that their power goal is one fourth that of ITER but their size is one 64th of ITER. The ITER magnets are being built also in Italy besides Japan and are ferried by ship from Riviera Ligure to Provence, since they are too big to enter the railway tunnels.The idea of using high magnetic fields (20 Tesla) goes back to Bruno Coppi and his Alcator, but of course there has been a development in superconducting materials.Let the best win.

29) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45405) Posted 29 Sep 2021 by tullio Post: A fusion reactor produces 14 MeV neutrons, not electricity. To produce electricity you must boil some water and produce vapor which turns the turbines. You are constrained by the laws of thermodynamics. I think the part of a fusion reactor needed to obtain this result is the divertor, which is being developed at Culham, UK, and at Frascati, Italy. It's a long way to Tipperary... Tullio
30) Message boards : LHC@home Science : Tokamak Energy develops new magnet protection technology (Message 45403) Posted 29 Sep 2021 by tullio Post: ENI, the Italian State oil firm, is advertising a fusion project called Sparc, wiith a spinoff partner from MIT, Commonwealth Fusion Energy. It boasts new superconducting magnets on a Tokamak reactor. Naturally MIT has a long history in fusion projects, starting with Alcator (Alto Campu Torus) designed by professor Bruno Coppi, whom I interviewed in 1969 at the Internationl Center for Theoretical Physics in Trieste, now named after Abdus Salam.The Alcator project was followed bu Ignitor, a joint Italian-Russian project. It should have been built at the Kurchatov Institute in Moscow but the project seems to have died. Tullio
31) Message boards : ATLAS application : Bad WUs? (Message 45301) Posted 7 Sep 2021 by tullio Post: They are taking about 6 hours on two cores (or processors?) of my Intel i5 9400F. It is a 3 cores CPU and six processors. OS is Windows 10. Tullio
32) Message boards : CMS Application : Condor ended after 9343 seconds. (Message 45229) Posted 19 Aug 2021 by tullio Post: Condor exits after 53351 s. Atlas tasks complete and validate. Tullio
33) Message boards : ATLAS application : queue is empty (Message 45139) Posted 19 Jul 2021 by tullio Post: Upload failed. Server is out of disk space. Tullio
34) Message boards : ATLAS application : queue is empty (Message 45131) Posted 17 Jul 2021 by tullio Post: I got 7 ATLAS tasks plus a number of SixTrack tasks, all completed. Tullio
35) Message boards : Number crunching : Porting Atlas to Aurora (Message 45053) Posted 10 Jun 2021 by tullio Post: Microbiome Immunity project of World Community Grid sais that it it was closing the BOINC project since the computing has been ported to Artificial Intelligence capable mainframes, such as the Perlmutter. Maybe SETi@home Nebula project should go the same way. Tullio
36) Message boards : Sixtrack Application : Sixtrack BOINC application on track to be ported to GPUs? (Message 45006) Posted 25 May 2021 by tullio Post: GPU tasks on OpenPandemics at WorldCommunityGrid take about ten minutes on my GTX 1060, I believe a Pascal chip board. On GPUGRID I have a task running since two days on a GTX 1650 board, which uses a Turing chip. GPU tasks running times depend on many variables, they are not always a solution. Tullio
37) Message boards : Number crunching : No Tasks Available (Message 44946) Posted 14 May 2021 by tullio Post: I am getting only ATLAS tasks on my Windows 10 PC, using VirtualBox. That is OK, since all CMS tasks would fail, for no known reason. Tullio
38) Message boards : Number crunching : VM Applications Errors (Message 44899) Posted 6 May 2021 by tullio Post: I can run SixTrack, Atlas and Theory tasks on my Windows 10 PC with 12 GB RAM with no problem, always using VirtualBox, its latest version. But CMS tasks all fail after about ten thousand seconds of Condor . God knows why. I have a 30 Mbit/s connection to my Internet provider and a WiFi connection from modem to PC which reaches 250 Mbit/s. Tullio
39) Message boards : CMS Application : A Heads Up for Vbox Extension Pack Users (Message 44792) Posted 22 Apr 2021 by tullio Post: I have downloaded the latest version of VirtualBox without downloading the Extension Pack. After installing it when I opened it it asked me if I wanted the Extension Pack and I said yes and Installed it. Tullio
40) Message boards : Number crunching : ghost tasks ? (Message 44759) Posted 16 Apr 2021 by tullio Post: No, I am running LHC@home on a PC with Intel i5 9400F. The Ryzen machine is crunching WCG and Rosetta@home. It also hosts a Linux Virtual Machine with SuSE Tumbleweed and kernel 5.11.11. It is running SixTrack with good results. Tullio
