1) Questions and Answers : Unix/Linux : BOINC 7.18.1 causes invalids (Message 1744) Posted 9 May 2022 by Tullio Post: I am using BOINC 7.18.1 on a Linux Virtual Machine running SuSE Tumbleweed, a development version of Linux updated very frequently. Now its kernel is 5.17.4. When the kernel is updted I have to reboot after installing it. It is running Einstein@home and QuChemPedIA@home. When rebooted it warns that 7.18.1 is a development version and might not work, but it does. Tullio
2) Message boards : Number crunching : Stuck tasks (Message 1718) Posted 1 Apr 2022 by Tullio Post: This looks the what happens on LHC ATLAS@home ,when I allow a single task to run on two processors.The CPU time is a double of the runtime. Tullio
3) Message boards : Number crunching : Inconclusive validation (Message 1712) Posted 13 Mar 2022 by Tullio Post: My Linux Virtual Machine runs SuSE Tumbleweed and, BOINC 7.18.1. Both nwchem and Einstein@home CPU tasks run on it. Tullio
4) Questions and Answers : Unix/Linux : BOINC 7.18.1 causes invalids (Message 1685) Posted 28 Feb 2022 by Tullio Post: I am using BOINC 7.18.1 on my Linux Virtual Machine running OpenSUSE Tumbleweed, and nwchem runs fine. Since the Tunbleweed kernel is frequently updated and I have to reboot, a message comes out that 7.18.1 is a development version and could cause errrors. Tullio
5) Message boards : Number crunching : Stuck tasks (Message 1643) Posted 27 Jan 2022 by Tullio Post: Om a Windows 11 PC with 12 GB RAM I have 3 QuChem tasks running plus a rosetta python which uses much RAM. Tullio
6) Message boards : Number crunching : Stuck tasks (Message 1642) Posted 27 Jan 2022 by Tullio Post: I am running QuChem on a Linux Virtual Machine on a Windows 10 host. The OS is OpenSuSE Tumbleweed, a development OS frequently updated.Kernel is 5.16.1. Tullio

8) Questions and Answers : Unix/Linux : Linux vs Windows (Message 1616) Posted 5 Jan 2022 by Tullio Post: I am using VirtualBox on QuChemPedIA@home, with 1900 MB RAM usage, Atllas@homw on LHC@homw, 4899 MB RAM, rosetta python, 6144 RAM, and I don't jhave any problem on Atlas and rosetta python. Onlu on QuChem i get some unmanageable task and I exit BOINC and restart. I am running nwchem on a Linux Virtual Machine using OpenSuSE Tumbleweed, which is a development version with BOINC 7.18.1, kernel 5.15.12 so ifrequently updated that I have to reboot almost daily, with no problem. It als runs Einstein@home. Tullio
9) Message boards : Number crunching : Why does this project only want to support Vbox 5.4.x? (Message 1610) Posted 29 Dec 2021 by Tullio Post: Electricity prices are raising also in Italy. I am paying 0.088 euro/kWh plus some fixed costs including the decommissioning of the 4 spent Italian nuclear reactors. I have been informed that from March 1 I shall pay 0,093 euro/kWh plus a fixed monthly cost of 9 euro, this because I am a long time user. But new users pay much more as I see from advertisements. Electricity producers often offer Amazon bonuses to appeal to customers. Tullio
10) Message boards : Number crunching : Why does this project only want to support Vbox 5.4.x? (Message 1608) Posted 28 Dec 2021 by Tullio Post: I have Einstein on another PC, a recent laptop with an AMD CPU with graphic capabilities . Another, my fastest AMD PC, runs WCG but also a Linux Virtual Machine running both Einstein and QuChem on a SuSE Tumbleweed Linux, which is a Development version and has a 5.15.8 kernel. It is frequently updated and I have to reboot it. On the Intel PC from which I am writing I run QuChem, Rosetta@home and, alternating, LHC@home. Another older laptop runs QuChem on a SuSE Leap 15.0. I am trying to distribute my BOINC projects on 4 PCs plus one Virtual Machine.All this hardware costs me about 50 euros/month in electricity. Tullio
11) Message boards : Number crunching : Why does this project only want to support Vbox 5.4.x? (Message 1606) Posted 28 Dec 2021 by Tullio Post: I have 12 GB RAM on an Intel i5 CPU 9400F running Windows 11 home edition and I am running two tasks at a time.The same PC can run two rosetta python tasks at the same time which need much more RAM. VBox uses 6344 MB. Tullio
12) Message boards : Number crunching : Why does this project only want to support Vbox 5.4.x? (Message 1603) Posted 27 Dec 2021 by Tullio Post: I am using VirtualBox.6.1.30 on this project, on Rosetta python and LHC@home without any problem. Tullio
13) Message boards : Number crunching : Waiting for memory (Message 1585) Posted 27 Nov 2021 by Tullio Post: I use GPU-Z to control my memory usage. Yes, i still get "waiting for memory" while running both QuChem and Rosetta python on VBox tasks. But I only have 12 GB RAM on this PC. On another I have 24 GB RAM but only 11 GB available on disk for BOINC, so Rosetta python will not run on it.It needs 19 GB. Tullio
14) Message boards : Number crunching : Waiting for memory (Message 1582) Posted 26 Nov 2021 by Tullio Post: In QuChem VBox uses 1900 MB RAM, in Atlas@home 4800 MB RAM, in Rosettta python 6344 MB RAM. So if you add them no wonder RAM is missing. Tullio
15) Message boards : Number crunching : Virtual enviorment unmanageable (Message 1580) Posted 25 Nov 2021 by Tullio Post: Now I am back in position 36. I am running also LHC@home and Rosetta python on the same VBox version. On "Nature" I've read tha Rosetta is RoseTTA and makes use of AI, following AlphaFold2 by Deep Mind (Google).: Tullio
16) Message boards : Number crunching : Virtual enviorment unmanageable (Message 1578) Posted 23 Nov 2021 by Tullio Post: Still absent, with 2 tasks running and 13 ready to run, none "unmanageable". Tullio
17) Message boards : Number crunching : Virtual enviorment unmanageable (Message 1577) Posted 23 Nov 2021 by Tullio Post: My RAC is now 2955 yet I am out of the credits list. My last position was 40. Tullio
18) Message boards : Number crunching : Virtual enviorment unmanageable (Message 1575) Posted 22 Nov 2021 by Tullio Post: Neither LHC@home nor rosetta python.which requests 6144 MB of RAM, ever signal an "unmanageable VM job". Only QuChem does and I kill and restart BOINC. Tullio
19) Message boards : Number crunching : Virtual enviorment unmanageable (Message 1569) Posted 21 Nov 2021 by Tullio Post: I am using VBox 6.1.28 on three projects, this one, rosetta python and LHC@home. When I get the "unmanageable" error I simply exit BOINC and restart it. My BOINC is 7.16.20. Tullio
20) Questions and Answers : Windows : how to solve problems related to virtualization (Message 1561) Posted 11 Nov 2021 by Tullio Post: I am runing 6 BOINC projects on 4 different CPUs,3 using Windows 10 and 11, one Linux and a Linux Virtual Machinwe. I am an old UNIX user in my professional life, and I was surprised to see that on QuChem most, if not all, Windows tasks using VirtualBox are faster than their Linux wingmen. So I stuck to Windows on ths project. Tullio
