On the other hand, for POEM (single-precision OpenCL), it makes a huge difference (58 secs with a free CPU core vs 8 hrs without). Your card does a POEM GPU task in 58 seconds?  Ack, what a typo! It is 55-58 minutes . What are your POEM timings like? PHEW! You scared me there for a moment. Thought I would need to scrape 5830s.  My processing times run 28-29 minutes if I run 1 at a time with 1 CPU goes free. I can do 3 at a time in 38-39 minutes but that puts the GPU load to 95% and requires 2 CPU cores. It also drags the remaining 6 CPU cores down to 97% efficiency on an i7-2600k so after testing I'm back to 1 at a time which runs the GPU at 45-50%. I also found that I can run 2 cards running 1 task each and use less power than running 1 card with 3 tasks. I'm hoping the POEM staff can work on their code to get better optimization. It's pretty CPU intensive compared to other apps and they still don't have a working app for Nvidia on Windows. On another note I'm so itching at the bit for WCG to get their HCC GPU app launched. It will be very interesting to see how quickly we burn through the project with all the cards that are standing by.

Hi Brink and kateiacy, Keep us informed. I have been running Mint 11, but that will be out of support soon if it is not already. So far it has been rock solid. I really hate having to to do any upgrades. I am not too smart about Linux, but so far Mint has made it easy. If Xubuntu is just as easy I may have to give that a try. Cheers I couldn't take it...I installed xubuntu 12.04 64bit. So far I like it a lot more than ubuntu. One thing is I still can't get boinc to work. When I select "attach to project" it immediately closes. This was the same in Ubuntu. So I did a end run and installed wine and boinctasks and attached that way. It attaches but every work unit gets a computation error. ARRRGH! Trying some other things to see if I can't get it. I won't be beat by a cornfuser, I mean computer.   |

How did you get Ubuntu or xubuntu? I used the repositories to install ubuntu with out a hitch. Weird that happens to you. Once I get my mini's external drive fixed, going to go back to Ubuntu on the dually. Just haven't decided on keeping 10.10 or trying 12.4.

Just installed boinc, boinc-client, and boinc-manager through the normal repositories using Synaptic.
----------------------------------------To install both ubnuntu and xubuntu I used a cd. Fresh install. [Edit 2 times, last edit by Former Member at May 1, 2012 2:04:50 AM] |

Brink, BOINC crashing when it tries to attach to projects sounds like a firewall issue. I wonder whether it's triggered by something about the security at your workplace.
----------------------------------------I've never had that happen to me with BOINC and any flavor of Ubuntu, but it happened when I tried Fedora a while ago. Internet searching turned up two steps that I had to take to make BOINC successfully connect with project servers under Fedora. My memory is way too feeble for me to remember what I had to do. Sorry! Glad that otherwise you're liking Xubuntu pretty well.  [Edit 1 times, last edit by kateiacy at May 1, 2012 2:20:04 AM] |

My processing times run 28-29 minutes if I run 1 at a time with 1 CPU goes free. So mine take right on twice as long with the same set-up. That's not bad for a very low-power card. I'm hoping the POEM staff can work on their code to get better optimization. It's pretty CPU intensive compared to other apps and they still don't have a working app for Nvidia on Windows. Agree, but I also am impressed by what they already have accomplished. I read that the latest 12.x Catalyst drivers make OpenCL less of a CPU hog. I think I still have the last 11.x, so I want to do the upgrade. On another note I'm so itching at the bit for WCG to get their HCC GPU app launched. It will be very interesting to see how quickly we burn through the project with all the cards that are standing by. Amen to that! And I sure hope it will include Linux! |

Going to move my systems over to Xtreme systems for a week to give them a hand on their super computer week. Will be back for sure though.

----------------------------------------Enjoy your time XS. As long as you're crunching it is good. I just acquired a Dell 1950 with one xeon e5410 in it and will be looking to add a second one. It has 4gb of memory and I am wondering if I also need to upgrade that to 8gb or if the 4gb will be sufficient. I also need to find a drive for it. I plan on putting some flavor of linux on it. I believe you had/have something similar so any advice will be appreciated. I think I can have it up and running for under $100. Thanks

Dual processor board or adding another complete system? 4 GB should do you. Those FSB dimms are still pricey. I had E5410s installed in my 1st Mac pro I upgraded from dual core. Not bad chips. With wu's eating more memory, and if that is a dual processor board that your going to add to, upgrade the memory.
----------------------------------------Was looking on Craigslist recently and saw a bunch of harpertown systems for sale pretty cheap. Solid systems for crunching, but eat the juice to. Let me know how well it crunches. Wasn't sure about jumping ship but it's only for a week. I learn allot from XS so my small contribution to them. Learned how to upgrade my AMD 6950 to basically a 6970. Can't wait to see how well it crunches WCG GPU wu's.
