Didn't think about that. Would I need to reinstall win7 or can I point the VM where win7 resides? Both are on separate disks under dual boot. Or, would a disk image work if a reinstall is required?

ken. et al,
The [arbitrary] benchmarks are [as a basis for credit claim] no longer used by WCG. Since conversion to server 700 the original claims are binned and the servers keep their own performance statistics for each device and compute a "claim". What it means is that for the most part, the claims and grants between Windows and Linux particularly latter with it's very high Integer benchmark, have largely aligned. Meaning, that if e.g. CFSW on both in dual boot on same machine take equal time, pretty equal credit is granted... which is fair. --//-- |

Agree on equal credit if both OS's complete a wu in same time. But if most projects lean toward Linux for faster completion times, would prefer Linux over bloated windows to crunch with. If it wasn't for a few programs I need to run under windows, I would not hesitate to crunch with Ubuntu. Just need to figure out the most efficient way to run both at the same time on same machine.

My question as a relatively non-technical cruncher is this: what CPU/memory combination will beat my current Phenom II 1090T X6/8GB/Win7 64 bit Ultimate machines? I want to add a third PC, and having had endless issues with Linux, want to stay with Win7. My project mix is:
----------------------------------------Project Computing for Sustainable Water Say No to Schistosoma GO Fight Against Malaria Drug Search for Leishmaniasis Computing for Clean Water Help Fight Childhood Cancer Help Conquer Cancer Human Proteome Folding - Phase 2 Discovering Dengue Drugs - Together - Phase 2 Beta Testing POEM- GPU version AMD or Intel are all the same to me: I want maximum output/minimum energy input. I will have a fight with my system support engineer (a retired electrical engineer) if Intel comes out on top, but I will cross that bridge should it be necessary.

Anyone ever try running Linux in a virtual machine on win 7 64? Am set up dual boot but need to run win7 for other things. Just curious how the benchmarks would compare. Why not run win 7 in a virtual machine under linux ? I checked with someone way smarter than I am and they stated it is easier to run linux in a vm under win 7 than the other way around. I did not ask why, but even if they had explained it I would probably not have understood all the details. Good luck. Cheers

Thanks Joe. Had a feeling about that but wasn't sure. What would you recommend for vm software for a noob? Last time I messed with vm was with fusion on the Mac a few years back.
----------------------------------------John, I would say intel will be better than AMD for maximum performance. Ivy bridge processors are looking pretty good from what I have been reading. Good power, less energy consumption. Check out movieman's thread on his dual 8 core beast. They are xeons but should give you an idea how well intel is working out.

Thanks Joe. I hang around on that site allot to learn win7. I did peek at that awhile back to get info on the different software to run a vm. Looks like I'll try virtual box.
----------------------------------------Next question. Already have dual boot set up. How much of a bag of hurt will it be to uninstall Ubuntu? Hate to have my MBR screwed up. Plan on reformatting my second drive to put the vm on it.

"How much of a bag of hurt will it be to uninstall Ubuntu?"
----------------------------------------It's pretty easy, use a Win7 disk to repair the MBR and de-GRUB the drive: http://support.microsoft.com/kb/927392 bootrec /fixmbr, if the 'Startup Repair' option doesn't work. Once done, you can go into W7 Admin/ Disk manager to delete the Ubu partitions. [Edit 1 times, last edit by Hardnews at Jun 7, 2012 6:36:50 AM] |
