2nd cpu now up and running - 1700XP running linux.

Twice now since I've been using F@H, it'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'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'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't cure the crash but it may stop you from losing your work.
Sort out your system instability - I'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.

try updaating your graphics driver,

has it always done this? or just recently?

Nothing wrong with my driver.
I happened this morning after my modem resets himself.

If i leave the Icon alone it's ok. Right-clicking is allowed, left is not.
As long as it's running it fine by me.
Hoovering over the icon gives all the info i need anyway.


Thanks for your help Ivy. ;)
 
im back!

i was gone to india for 2 weeks and couple of dayz.....was fun but got sick and had to get a shot on my butt :angry: :(

well now im back to my 24/7 folding...

lots of things changed....

i saw the new site and stuff...

crazy stuff keep it up guyz :)
 
30,000 over here, :)

also team just passed 6000 wu mark.

ive taken 2 of my machines of full time folding for electrcity use, which isnt much as there laptops, and the noise, so they get put off at night now. :(
 
Each type has it's own core, that's the very thing that differentiates them.

I've got a core 79 on one machine and I'm pretty sure that's Dgromacs. Not sure what cores Ambers and QMDs use.

QMD cores may use up to 1GB of main memory (source), possibly even more, but they will only run on Intel chips.
 
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.
 
dose eny1 know about overclocking ?How dose it work?do i need a prog?to check my cpu heat level do i need a senser?sorry to ask so much Q's but i want to learn about this stuff. :D
