Posted 30 May 2020 by Sesson Post: The jet charge plots at http://mcplots.cern.ch/?query=plots,ppppbar,jets,jet_charge look so bad that all of these generators are off by huge differences.  However the referenced experimental article from CMS said predictions of PYTHIA8 and HERWIG++ matched almost perfectly with experiment results. Quite strange.  http://cms-results.web.cern.ch/cms-results/public-results/publications/SMP-15-003/ |

Posted 13 May 2020 by Sesson Post: LHC@home sends tasks directly from HTCondor to your VirtualBox, BOINC server only sends you pseudo-task that just means there is something to do using VirtualBox. I can't believe Folding@home is more complex than LHC@home, and yet LHC@home is a BOINC project. |

Posted 29 Apr 2020 by Sesson Post: Yes, I run say 50 tasks. In assume in theory yes but seems like for LHC, more cores is better, clock speed doesn't see so important. Believe it or not, I see identical credits/elapsed time ratio when I underclock my CPU to 800MHz from its stock frequency of 2500MHz. It seems LHC@home gives credits only based on your total time and BOINC benchmark. Your actual contribution to LHC@home can be seen at mcplots website. So if you want more science results, boost all your cores and improve your network speed, or even better install linux inside your VirtualBox and run natives there. But if you just want more credits/W, underclock your CPU, make your network slower, and run as many tasks in parallel as possible without regard to cache performance. |

Posted 28 Apr 2020 by Sesson Post: Thank you for providing such a great educational resource at http://mcplots.cern.ch/ where anyone can see how our research in particle physics has progressed so far and what is the current state. Until now I was assuming scientists has modeled the LHC experiment to a precision on the order of 1e-10 or better, but the plots and predictions at mcplots is a bit of, disappointing. It is not uncommon to see theorical prediction go completely off the experimental uncertainty, sometimes by an order of magnitude! No wonder why scientists need such a strict standard of 5σ confidence in order to announce a discovery. I have been diving in CERN publications in the hope that I can interpret these plots which I contributed to one day. But apart from authors of LHC@home team, I failed to see any "mcplots" being published. Then a big question arises: are these resources just "educational"? Has any scientist not from LHC@home team published one of these plots? |

Posted 17 Apr 2020 by Sesson Post: While one of the reasons for my participation in LHC@home is its less CPU utilization to keep power in control, I'm tired of waiting and watching these uncached tasks. I should better set up a linux in my VirtualBox and run native tasks there. |

Setting up a local squid cache for a home cluster - old comments
(Message 42190)
Posted 16 Apr 2020 by Sesson Post: I am using the following conf from the example squid.conf. I decreased the disk cache min size to keep more data in squid. The squid installation is not very big, but it is now 1.21GB including everything cached inside. # You don't believe this is enough? # For sure, it is! cache_mem 192 MB maximum_object_size_in_memory 24 KB memory_replacement_policy heap GDSF # Keep it large enough to store vdi files in the cache. # See extra section 1 how to avoid onetimers eating up your storage. # min-size=xxx keeps very small files away from your disk cache_replacement_policy heap LFUDA maximum_object_size 6144 MB cache_dir aufs /var/cache/squid/0 32000 16 64 min-size=200 The squid was mostly working fine but some tasks still don't like it. Here is an example from access_squid.log when an uncached task started: 192.168.1.236 3128 - - [16/Apr/2020:13:21:32 +0800] "POST http://lhcathome-upload.cern.ch/lhcathome_cgi/file_upload_handler HTTP/1.1" 200 960 "-" "BOINC client (windows_x86_64 7.16.5)" TCP_MISS:HIER_DIRECT After that access_squid.log doesn't log any activity until an Einstein@home GPU task finished, but the network is busy, netstat shows VBoxHeadless.exe is connected to Cloudflare, not squid.exe. |

Setting up a local squid cache for a home cluster - old comments
(Message 42184)
Posted 15 Apr 2020 by Sesson Post: I set up squid on Windows on the same machine running BOINC just yesterday and it is working. Here are steps: 1. Download Squid from https://squid.diladele.com/ and install it. I'm running Rosetta@home and Einstein@home as well as Test4Theory and the squid cache is about 1GB in size, please install it on a drive with sufficient disk space. Let's say it is installed at C:/Squid/ for the sake of simplicity. 2. Right click on the squid tray to stop squid service and open squid.conf. Copy the example squid.conf into your squid.conf. 3. Search for http_port setting and change it to http_port <LAN IP Address>:3128. Here you cannot use "localhost" nor "127.0.0.1", you must use a IP address that is accessible from within the VM. You may configurate your LAN router to assign your computer a fixed LAN IP such as 192.168.2.1 and use that. An IP that is in a VirtualBox LAN might work. 4. In command prompt under C:/Squid/, run bin/squid -zto create subdirectories. I created C:\Squid\var\cache\squid\0directory manually before, but it might be not necessary. 5. Now configurate BOINC to use a HTTP proxy at <LAN IP Address>:3128. You can now start downloading LHC@home tasks.

(Message 40872)
Posted 9 Dec 2019 by Sesson Post: Please don't send me these tasks with deadline of just 7 days. I just completed my first 1e7turns task with more than 96 hours of processing by turnning on my computer when it should be powered off, and allowing it to use single core boosting which is not productive overall. I'm completing my second 1e7turns task now. No new tasks. |
