Guess I'll have to wait on a new build. Tiger direct has a 24 hr sale on a Asus i5 laptop for $399 after rebate. Here is a link if interested. http://www.tigerdirect.com/applications/Searc...No=3924783&CatId=4935 Looks like a nice machine, Bearcat! Let us know how you like it! I crunch on laptops. I have to monitor the CPU temps. The default "standard setting" from WCG generally work ok, although if the room is warm, I have to reduce below the default 60% CPU usage or cut out some cores. GPU crunching has generated too much heat for my one laptop that can do it, so I gave up on that. I crunched 24/7 on one laptop for a year when I first joined WCG. Now I have it crunching only when I have it on during the day. It is still going strong, but now that I have desktops to crunch with, I wouldn't push a laptop as hard as I did that one at first. Our new AMD desktop arrived yesterday. I didn't have a chance last night to do more than install BOINC and attach to WCG. My husband was busily installing Dragon Naturally Speaking and the other software he uses. So far he's really pleased with the speed. I'll tinker with the BOINC settings tonight, and hopefully get POEM running on it. I'll let you know how it all goes. ![]() |

I suggest taking the battery out for crunching...or it will be worthless within a year or two from the heat (batteries #1 enemy). Speaking from personal experience. Other than that try to place it on a surface with unrestricted airflow to the bottom (like a metal grating or something) and you shouldn't have any issues running 24/7 with it.

Supposed to be better than bulldozer. So far am liking the laptop. Thought it was a real good deal to good to pass up. Have only owned 2 laptops ever, a mac G4 and a Dell single core in 2005. This laptop had windows 7 premium. Both my big rigs have pro so contemplating bumping up if i find its worth it. Thanks for the info on crunching with a laptop. Ryan, thanks for the info too.

OK, I'm pumped. I came home from work to find that the new computer had received 4 GPU beta test WUs. I bumped them to the head of the line, and two have completed and uploaded. I knew this APU's GPU was supposed to be OpenCL capable and double-precision; now the OpenCL part is already confirmed. I am very excited about *finally* being able to participate in WCG's GPU efforts. My machines are Linux; glad I can share this Windows machine of my husband's.
----------------------------------------Yes, Bearcat, this is one of the new Trinity family of desktop APUs. I think it's going to be replaced with an even newer family later this year (which is why I could get this machine for less than $500 with 10 Gb of memory and a 1 TB hard drive). The CPU is not fast. CFSW WUs are taking about 43 minutes when running 4 at a time (or 3 + a GPU beta). But if a 65-watt chip can support 3 CPU threads and a GPU all crunching at once at a reasonable pace, that is a lot of FLOPS per watt. Once these exciting betas are done, I'll set BOINC not to run the GPU while the system is in use -- I don't want anything to interfere with my husband's use of the machine. ![]() |

Pull the battery out when your crunching. I also bought a cheap laptop base thingy that has 2 fans in it blowing up. Runs off a USB connection.

Thanks Brink. That looks pretty cool. Don't think I'll crunch more than one thread at a time at first, until I can see how it goes. Would be nice if WCG had projects for laptops that had a 30 day return time. Will have to find a project that has short run times, like HCC was.
----------------------------------------This laptop has the intel 4000 integrated gpu. Anyone try gpu crunching with this? Curious if it's any good. Thanks for all the help.

Kate, looks like a good deal on that pc. Am hoping AMD can get there processors back to competing with intel. Their bulldozer chips flopped pretty bad considering all the hype they gave it. Their new APU coming out is supposed to be pretty good.

Brink, just looked at our team stats. I just moved into 3rd place on points. I'll be knocking on your door in the near future.

I have solve heat problem removing DVD -station, so literally one end of my laptops are wide open. When ever need it (very rarely), just plug it back. Does not look cool on meetings, but I'm way too old to look cool. More important is inner coolness. As far as I can say, best way protect battery is keep it on full charge all the time. A.k.a. always when possible, plugged. This one is two years old, but is absolutely on mint condition. When I need to lean on this baby, I still sure can ![]() ![]() |

When I need to lean on this baby, I still sure can The best longetivity for Li-ion batteries is to keep them 40-60% charged and located in a cool but not freezing area (like 40-50 degrees F, 5-10C). Given these conditions a battery loses about 2-6% of its charge capacity per year. A battery charged to 100% most of the time will lose about 20% of its charge capacity per year, and even more once significant heat is introduced. ![]() [Edit 1 times, last edit by ryan222h at Sep 15, 2012 12:47:54 PM] |
