I didn't see anything I recognized in your list of methods.

I double click a VMWare Player icon and pick which of the 2 VM's to start. I'm using notfred's diskless appliance and these instructions- http://www.ocforums.com/showthread.php?t=599272

Even with the stock v2.10, the VM's give me more than double the points of the Win SMP on Q6600s and a Q9550. I'd love to get the speed of the 2.08 back, but I have no idea how to do it with the setup I'm running.

Is this something I can edit into the .vmx file?

I have 3 Q6600's on XP32 and the Q9550 is vista64.

The new VMWare player can run VM using 4 cores ;) I think it could help you

I don't know notfred's ... I prefer to have full control on my VM (just in case :hehe ).

You have to find a way to get access to command line inside your VM, to be able enter the command to fix the performance issue before launching the client, and then, to launch the client manually.

If no one who knows notfred's shows up, do the rest of you have a preferred VM and Linux flavor? How about a guide for installing and running it?

Please be gentle. I had to dig out my DOS for Dummies book to figure out how to install S@H. No, really. I don't even do command line, so you can figure I'm very eager to try to learn about a terminal. [/fear and sarcasm]

I'm willing to give it a shot.:think

I'll be installing this on XP or Vista. Which VMware product would I use for the Ubuntu Server? Player is the only one I've used. Which version of Ubuntu Server?

With Player 3 (beta or RC), you could use 4 cores for your VM ;)

There's not many different versions for Server, but of course you need 64 bits version, and if you plan to use SMP client, you should use 8.04 instead of 9.04 (or wait for 9.10).

tear and Weedacres seem to be adressing this at the Folding Forum, so I'll be following that AND researching your suggestions.:top

I've been asleep at the switch and missed this new thread. Here's the comment I just posted:

If you've been following the 2.10 slowdown thread on FAH you'll see that this fix does not work on notfreds vm appliances (at least on the 3 I've tested it on). On 2 core machines it will only fold on 1 core after issuing export MPICH_NO_LOCAL=1. On 4 core machines 2 cores run at about 70% and the other 2 are idle.
tear is working to recreate this and try to come up with a fix.

Quotation:
You have to find a way to get access to command line inside your VM, to be able enter the command to fix the performance issue before launching the client, and then, to launch the client manually.


When using the notfreds VM appliance, after it's running type in "root". Change directories to the folding directory "cd /etc/folding/1 (or 2)". At this you have to stop the folding operation. I use "killall fah6". It takes a few seconds for it to wind down. Once your task managers shows flatline, you can enter the "fix" "export MPICH_NO_LOCAL=1". Then restart folding with "./fah6".

Before doing this I'd check the last couple of pages of the FAH forum on 2.10 frametimes here:
]http://foldingforum.org/viewtopic.php?f=44&t=11367&start=135]

"tear" has been working hard to resolve this issue and deserves a lot of credit for the solution he's come up with. What I don't understand is why I'm the only one reporting this notfreds problem. I can't be the only one using the notfreds VMWare appliance. :frodo:

edit: After a great deal of work by tear and uncle_fuzzy's testing the problem was a lack of the -smp paramater. When restarting the notfreds client one must use ./fah6 -smp or -smp 4.

I'm using 8 copies of notfred's with Player 2.x.x(?) on 4 quads. I just followed someone else's directions to run them. You may be the only one reporting problems because the rest are dummies like me who don't (didn't?) have a clue how to implement tear's "fix". Until installing S@H, I hadn't messed with anything aproaching DOS for years. I didn't have a clue how to "work" Linux.

I'll be watching, and perhaps trying, the work you and tear are doing. I'll also try to follow toTOW's suggestion. I've downloaded Player 3 and the ISO for Ubuntu Server 8.04. Tomorrow, I'll try to figure out what to do with them.:|

I have 3 Q6600's with XP32 and a Q9550 with Vista64. Where should I put the new VM and which gets to try tears ideas?

The 2.10 performance problem primarily effects 2 core folding. At least that's what the experts are saying. I think they are wrong and that 4 core folding is also suffering although not near as much as 2 core. My 2 core performance dropped by 18% while my 4 core performance only dropped by about 4%. The good news is that 2.10 quickly eliminated the bad wu's which were causing a lot more performance problems.

You could test it with your current Player setup. Monitor task manager before and after and if you have the same problem as I do you'll see one of the cores go idle. You'll have to restart that VM and should be back in business.

If you're going to install Player 3 then you should be folding on 4 cores to take advantage of it and probably don't need the "fix". I'd try it one any one of your quads to make sure it works and if it does migrate all to Player 3 folding on 4 cores.

Now you know why I prefer to use my own VM rather than notfred's ? ;)

Yeah, yeah, you don't have to rub it in!

...especially on 2 forums.:(

I've got Player 3 installed on one of the machines, and will experiment with Ubuntu when the current WUs finish. I tried starting just one VM with 4 cores, but the appliance I have wouldn't let me. If I can't figure out a new OS, I'll just have to find another appliance that will let me use 4 cores.

Appliance ... appliance ... you should create your own VM (Player 3.0 should allow you to do so) and then install a regular Linux distribution :p

Yeah, yeah, give the old guy a break. Some of us are tired of learning a new OS. I started with DOS 5.0, 6.0. 6.22. Windows 3.0, 3.11, 95, 98, 98SE, XP, and Vista. That's a lot in just 12-14 years. I'm supposed to get a free W7 for my new laptop. ANOTHER OS to learn!

I edited the .vmx file in my APPLIANCE to change numvcpus = "2" to "4". applied tears fix with "-smp 4", and I'm folding something with 4 cores at just under a 5 minute frame time on a Q6600@3.4GHz. My calculator says that's about 7200 PPD. Unfortunately, the only way I can monitor it is in the VM window- fahmon and my browser can't find it, anymore.

I did grab a copy of Ubuntu Server 8.04, as you suggested, and I've burned the ISO to a disk. I foresee installation being a time consuming project, so it will have to wait until next weekend, at the earliest. Player 3 does have a separate Help file on installing a guest OS in VM, but I haven't had time to study it.
