Here's your chance to contribute to a FAQ table. Please stay strictly on the topic as I'm brewing over a few more tables like the file sizes transmitted for each project (ripping other's ideas ;>).
----------------------------------------Input needed is: 1. Operating System 2. Agent and if BOINC, the version. 3. Project (FA@H, GC, HPF2) 4. ACTUAL MAX/PEAK RAM use by the science process (they start in taskmanager with WCG) 5. ACTUAL MAX/PEAK Swapfile(Virtual Memory Use) 6. BOINC PREFERENCE % for Busy(work) and IDLE Crunching time 7. Actual physical RAM 8. 'Leave in Memory' On or Off (really outdated as project switching is checkpoint dictated). What you see below is what was pulled from the lengthy Systems Requirement page with a few adjustments for a few projects from recent observation.... sizes change. Footnotes will be added if more ideas come to mind. If you ran 5 or 50 of the same project, does not matter.... I think there is some nifty tool to record the highest values, rather than staring at Task-Managers 'Peak Use' columns before a job ends. (someone will tell me) AND, the values will be the max and not the averages as tables elsewhere have attempted to capture. These will be worst case values, with a safety margin for unexpected blips. Nothing worse than a job that runs out of space. Apologies to the visual impaired, but it's a picture.

Linux/BOINC 5.8.15 i686-pc-linux-gnu/FA@H/125MB/?/?/?/?
----------------------------------------Linux/BOINC 5.8.15 i686-pc-linux-gnu/HPF2/75MB/?/?/?/? (The ones with ? are either irrelevant and/or vary in an obvious fashion depending on the other factors. eg. A FA@H process running on a 256MB machine uses no swap space, while one running on a 128MB machine uses swap space.) HPF2 seems to take 60-65MB most of the time, but spikes up to 75MB briefly at times. This leads me to the obvious questions: Why does HPF2 "require" 256MB RAM and can you get that seemingly pointless restriction charged?

Hi Kremmen,
----------------------------------------thanks for this contribution. Why I ask for actuals IS, so the matrix can be updated and where appropriate the techs can be asked to tweak the system parameters :D The FA@H on Linux is very strange. Maybe because there is presently no graphics (?), it uses much less. On Windows it does 128 over 500 at times (actually saw highest of 453, but keeping it save). The more ram you have, the less VM is used IF you have set the BOINC parameters to allow that use! PS. Some of the specs are driven by concern over jobs taking too long and part time crunchers loosing too much progress in stop-start scenarios. The Checkpoint Save FAQ is reading material to optimize!

These are little servers that don't even have X running. They don't know what graphics is. :)
(IMHO, the whole concept of grid computing projects running graphical output is wasteful and self-defeating.) #5 is meaningless, as it's for the whole machine and depends on what other processes are running and, worse still, on how much RAM linux feels like keeping aside for cache, which in turn depends on I/O load, etc. #6 and #8 make no difference to anything that matters. (The maximum process size will still be the same.) #7 makes no difference to anything except #5, which is meaningless. |

----------------------------------------This is the message list from my slowest machine. I hope you can find it useful. The FAAH job has been running for 15 hours now and shows continuing progress, 45% done. It will be about a 34 hour job. So far task manager has reported a peak memory requirement of 86,444K. I will let you know if it finishes without a problem. Let me know if you would like any other info.

Let's go!
----------------------------------------1. Operating System 2. Agent and if BOINC, the version. 3. Project (FA@H, GC, HPF2) 4. ACTUAL MAX RAM 4.1 Average RAM observed most of the time 5. Max Swapfile (Virtual Memory) observed 6. BOINC memory usage preference % for Busy(work) and Idle Crunching time 7. Actual physical RAM 8. 'Leave in Memory' On or Off 1 2 3 4 4.1 5 6 7 8% Busy changed from 50 to 75 during last job when seeing that it was so low. But it had no effect at all on figures shown for that job. Thanks for starting this huge task and good luck. Jean. ---------------------------------------- [Edit 1 times, last edit by JmBoullier at Jul 6, 2007 12:58:32 AM] |

Linux/BOINC 5.8.15 i686-pc-linux-gnu/AC@H/455MB/?/?/?/?
This is one nasty project, from the point of view of determining minimum requirements. It spends almost 99% of its time using 125MB or less and then sporadically uses over 3 times as much RAM for a total of just over 1% of its runtime. |
