Hello All,
Does anyone know if WCG projects work better on Linux (specifically Ubuntu) or on Windows OS (Win 7), or does it depend entirely on how the researchers developed things on their end? Thank you for your input. |

Linux will run the VINA jobs for FAAH about 50% faster than Windows on the same hardware. I think the MCM1 jobs are comparable on either OS.

Great, thanks Sgt.Joe. What about the Clean Energy Project? Have you noticed if those tasks work with the same speed?

Hello vitali.dedkov,
Linux 64 bit is faster running CEP2. Lawrence |

Ok thanks guys. Does anyone know why those run faster in a Linux vs Windows environment?
I do not have much experience in Linux so I am not familiar with it and just stumbled on Ubuntu recently. |

Hello vitali.dedkov,
The Linux compiler builds faster programs. Also, CEP2 uses the disk I/O a lot. Linux has faster I/O, which is rarely noticeable, but most programs use very little I/O compared with CEP2. Lawrence |

Lawrence Also for this reason, and slightly off-your-original-topic, if you can move your BOINC/slots folder to RAM (presuming you have enough), your CEP2 work units should complete a little quicker as well (and save HDD or SSD wear and tear), regardless of if running Windows or Linux  |

Could you also explain what you mean moving the folder to RAM? I did notice that when I start my task manager all the of Vina, Clean Energy, and Mapping tasks are set to low priority instead of normal. Would that affect their speed in any way. Basically what role does CPU/Ram play in Crunching. Sorry if that is too general a question. I am not an experienced cruncher and would welcome any tips. That is okay if it is of the original topic, that is how new ideas come up all the time :). |

I did notice that when I start my task manager all the of Vina, Clean Energy, and Mapping tasks are set to low priority instead of normal By design, they are supposed to run at low priority so they do not interfere with any of the other work you do on the computer. When other jobs in a normal priority start, the BOINC jobs are supposed to get out of the way. As long as you have enough RAM to run comfortably, you are fine. Any addition RAM over and above what BOINC and your other programs are using is just not being used. For instance I have 4gb of memory of which the peak usage for BOINC is about 400 mb ( 1/10 of my total) for 4 concurrent MCM1 jobs. Other BOINC programs may use more or less. More RAM than the programs use will not speed up their progress. Cheers
