I am running Win ME with 256mb memory and a P-4 1.4MZ chip with a 40MB hard drive. I thought this project may push the limits of my system, so I'm providing my experience with the new program.
Just finished my first molecule in the AutoDock system without too much stress. I thought my swap file would be used extensively, resulting in a rapid fragmentation of the HD but that did not occur. On the second run with about 6.8% completion, I had about four IE windows open reading the Scripps Institute description of AutoDock and AutoGrid. When I opened the program to see its progress, I experienced a run time error and the program shut down. I reopened it without incident, and within about 10 minutes it had progressed to 7% completion and appears all 3 AutoDock windows, A, B, and C are up and running. If this computer can manage it, I think most others should do well. |

I'll chip in with my own experience. I'm using an 800Mhz Athlon with 512MB RAM and a 20GB HD, on WinXP Home SP2. I just completed my very first WU
 in about 20 hours. No problems with the graphics. About 70% into the WU, I experienced a lock-up and had to hard reset. No idea what happened; I left the PC and had the monitor turned off. Still, the WU completed and was supposedly validated successfully (I got 381 points for it!), so all is well, I guess. |

I think the real test comes in when I put my IBM laptop to the test: Celery 366MHz with 128mb of RAM. I put the page file to 1024MB, so we'll see if it takes it. It may take a while though, I'm 40 hours into a Proteome WU and it's about 12% done.
---------------------------------------- Edit: Nevermind, just realized the min. requirement is 550MHz proc. Hmmm... Overclock this big bad machine? The proc already runs at 80*C though... [Edit 1 times, last edit by Former Member at Nov 21, 2005 4:21:04 PM] |

Thank you everyone for sharing your feedback. This kind of feedback really helps in determining from a user perspective how well we did in selecting system requirements. It seems that so far the new application isn't causing your machine to thrash too much, which is good.
In general, the application should use more virtual memory than anything, so increasing your page file usage will help windows out, but in reality it might not actually have to utilize it and swap to disk that often, depending on what else you are running. This should allow fairly good performance with lower amounts of RAM. |

I didn't push it. One machine is a Pentium III/500. I just made a profile for it to run Rosetta only.

That puts this one on the edge, I noticed the test units running over the weekend, and increased my swapfile. The change has helped, I've had no problems running the new project. No crashes, lockups, only it's a little slow processing the WUs. Rick |

I have a P4 3.2Ghz, 1Gb memory, 250gb hd. With the new AIDS@home project with the exception of a slight increase in memory usage I have not noticed much difference in system resource utilization. Total memory utilization is well below 1Gb. Processor at 100% (100F) and case temp (80F) have remained the same as with the HPF project.

Hello i've just joined this great project, with a p4 3Ghz prescott i think -HT (enabled)-512M (memtested86 ok)-MSI Neo2v 865 pe with latest bios- ati 7000 LE - XP SP1 no patches and no other bloated appz (messengers-like etc) and only GPL/BSD licenced appz.
----------------------------------------I've normally no other tasks running except SpeedFan. CPU usage shows 100% in one and 25% in the other. the PC is 7/7 24/24. until now i've noticed no problems except one freeze for unknown reasons. -I have three questions : my CPU is 75 C and northbridge 43 C, is that ok ? i mean what is the max temp a P4 3Ghz prescott can bear before desintigrating :) (without WCG they are 49 C and 30 C) (i have one alim fan, one fan for P4 from the same intel box and one 12'' in the rear of the cassis). -I'm not very experienced in hardware, so please tell me how could I know that the CPU (as it is the most stressed I think) is dying/burning/thermoexploding ? I have no prob with 1 freeze in 24h as far as this does not destroy the PC. -When the cpu freezes and the WCG launches again, will it be able to resume from last checkpoint or could that trash the results, i mean are there checksums-like algorithms built into the software in order to keep it from sending bad/false/corrupt results ? Thanks and keep crunching, burning CPUs is just a little sacrifice for this great project   |

Hello nealschim,
Maximum temperatures for a P4 depend on a number of factors. It is complicated and you have to know your package. Here is an online datasheet: http://users.erols.com/chare/elec.htm Pentiums are listed toward the bottom. Regardless of what you read, you should get that temperature below 70C. For starters, turn off hyperthreading. It is a nice feature, but you need to start cooling off. We do have checkpoints in our programs. If you turn off the computer, you will start back up at the last checkpoint. We intend to look into putting more checkpoints into the FAAH program (AutoDock). Don't worry about rebooting. Just make sure your computer stays the marathon. Here is Viktors' longest post, talking about CPU Temperature and how to chill down: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=2683 I think this should get you fixed up. mycrofth |
