All of my HFCC stayed between 19 to 24 hours. Here is the final server setup: Server 1: 2x Intel Pentium III @ 1.26Ghz 512Kb L2 Cache Server 2: 1x Intel Pentium III Xeon @ 1.00Ghz 256Kb L2 Cache Both servers have an SCSI 40GB Hard Disk @ Volume config on the RAID controller. While the Xeon is lower in Ghz, it performs a little faster (1 to 2 hours less time per HFCC workunit) than the regular Pentium III which is clocked higher and has more cache. Of course Server 1 processes 2 workunits at a time since it is dual processor. One thing to consider is the physical size of the workunit for each project, as long as it fits into your L2 cache it will be fast, if it doesn't fit it will be swapping to the hard drive all the time and taking longer to crunch. With two different cache sizes there you might have to be careful with how you allocate your resources.   |

No idea how you fit an "in RAM" work unit occupying 50-500Mb into an L2 of 512Kb, but maybe [offering an escape], you were thinking of the data blocks exchange to swap file [which on Linux is mostly in RAM]? Anyway, no ho capiscono how it's worded here.

I would be curious to have some power consumption figures for the servers. If there is the possibility to measure at the wall socket the wattage I would be interested to see how those old servers behave.

Anyway, no ho capiscono how it's worded here. Well for instance I am running HCC units right now and each one is using about 31k of memory, that easily fits into my cache so there is no swapping to the much slower hard drive. I am actually running six of those at once on this pc and am finishing them in just under 1.5 hours each, I am running 64bit Win7 Ultimate with 16 GB of ram. I am also running two gpu units, from Moo, which take about 41k each, but all of that fits into my gpu memory, making them essentially stand alone also. A small of the cpu is needed to load and unload the gpu units to and from the gpu, once on the gpu the units finish without any more help from the cpu, or pc memory, until a new unit is needed. |

31k for an HCC job in core RAM? You're sure?
----------------------------------------edit: This is what I have on the matrix sheet, in Megabytes: 35 / 57 or variable from 37 to 57 in observational, mind you that's a while ago. These are the official numbers [worst case maximum]: http://www.worldcommunitygrid.org/help/viewTopic.do?shortName=minimumreq [Edit 2 times, last edit by Former Member at Aug 22, 2012 4:11:34 PM] |

Well, the university servers all have 1GB of RAM, and they are very efficient in processing the workunits. They perform just great. I don't know how much ram the workunits takes since I haven't looked into that.

So YOU are correct it is 31 THOUSAND K, NOT 31 K as I said above! |

Team, these are my benchmarks, would it make a difference if i buy more RAM with the WU handling performance ?

No, you should not need any more RAM if you are only crunching. If you are doing other things in addition to crunching it may pay to upgrade. All of the WU are CPU bound, not memory bound. (In addition CEP2 may be disk I/O bound if running several at a time.)
