erm..although I am still on the "bla blah blah" warning from brahbarossa, I have one question, are you sure? It begins with a 3?.. Right?

then continues with a 4....

Sweet using the -forceSSE switch speed up my folding quite a bit.

[faisay]

ok i came back from school early....toaday turn over day...so u could skip classes so i came early...

ok ill expain gromacs

There are 2 cores (FAHCore_78.exe and FAHCore_65.exe) you can check which core you are running by pushing CTRL+ALT+DELETE...

CORE_78 is gromacs the new fast one...
CORE_65 is the slow one

most of you probably have core_65 so u want it to be core_78

Method:
Either make a shorcut or use the startup shortcut (which is already there) from "winFAH.exe" which is probably in your "folding@home directory" (in program files)

now go to your shortcut and RIGHT CLICK>PROPERTIES then change this:
add -advmethods -forceasm at the end of the target after the (")
just copy and paste this.... "C:\Program Files\Folding@Home\winFAH.exe" -advmethods -forceasm (if ur using the default directory..)

PIC:

it should look something like tht

then click ok and when the WU ur working on right now is done the "winfah.exe" will AUTOMATICALLY download the new core_78 and you will be folding gromacs in ur next project
u can check ur LOG file to see if it is using the gromacs are not at the beginng of a project..
but sometimes you dont always get gromacs....so then u will get the use the old core...

remember the old core projects are usually out of 400..

but you will see a big difference in the folding speed with the gromacs for sure

i hope this explains it well....
if u still have questions feel free to ask...

or someone want to do it?

Since your processor only has one Floating Point Unit, and most of the work is done by the FPU, you will see very little advantage. Pandegroup actually prefer that you don't run a HT processor in this way.

If you really want to run 2 copies you can do so:

You have to make a completely separate folder for each copy.

Create a new folder (call it something like Folding2) and copy just the console executable into it. If you copy anything else it may not work.

Now start a command prompt, change to the new folder, and run the console program. There will be no config file so it will think this is the first run, consequently it will automatically run the config. I've never found the need to use the -local setting.

It will ask you if you want to change the advanced settings as part of the config. The only thing you need to make sure is different is the machine ID - set it to 2. It will also ask you if you want to install it as a service - it's a good idea to do this.

If you decide to install it as a service, you should stop the program immediately after completing the config (press ctrl-c a couple of times), then go to control panel/admin tools/services and start the service.

Twice now since I&#39;ve been using F@H, it&#39;s crashed taking hours of CPU time with it. The first time I lost about 71% of a work unit, due to a communications error with the server:

"[06:21:45] Completed 355000 out of 500000 steps (71)
[06:33:02] CoreStatus = 1 (1)
[06:33:02] Client-core communications error: ERROR 0x1
[06:33:02] Deleting current work unit & continuing...
[06:33:22] - Preparing to get new work unit...
[06:33:24] + Attempting to get work packet
[06:33:24] - Connecting to assignment server
[06:33:27] + Could not connect to Assignment Server
[06:33:27] + Could not connect to Assignment Server 2
[06:33:27] + Couldn&#39;t get work instructions.
[06:33:27] - Error: Attempt #1 to get work failed, and no other work to do.
Waiting before retry."

Which prompted me to stop using it. I retried it the other day, got one WU completed. My PC crashed again today, and no surprise, F@H lost its WU again:

"[16:33:30] Completed 480000 out of 500000 steps (96)"

The first bit (up to [06:33:02]) indicates some sort of file system error, not a communication error. Basically it could not write the results to the disk, presumably because it thought the file was corrupt. Rather than send bad results back to the source it deleted them.

The next part (up to [06:33:27]) is an attempt to get another WU. First of all it has to connect to an assignment server. This then routes the request to a Work Unit server, but as the error messages suggest it could not even connect to the assignment server.

Both of these events occuring together suggest you have some inherent instability in your system, which is causing the crash. I&#39;m guessing that you are using FAT32 file system. When your system crashes with FAT32, the last part of the file will be lost (just like with Kazaa). So F@H thinks your results are corrupt and discards them (again, like Kazaa downloads).

Suggestions:
Convert to NTFS if you are using FAT32. It won&#39;t cure the crash but it may stop you from losing your work.
Sort out your system instability - I&#39;ve found from experience that raising Vcore slightly (0.025V is usually enough) can cure this problem, even though the system is theoretically running at the correct settings. Watch your temps though.
