UPDATE:
I deleted the bad WU with "-delete x" and tried downloading a new WU but got the same. It died again after 2 frames.
How do I get a different WU? Configure a new client with a different MachineID or something?

UPDATE2:
So after 3 failed attempts (and after deleting the work folder and queue.dat files 3 times) I got a different WU.
This time it's a Project: 2665 (Run 1, Clone 183, Gen 39) WU and it finished without problems.

Posted: **Wed Aug 13, 2008 6:30 pm**

Running 2665 (Run 3, Clone 165, Gen 40) I got a NaN at 19%.

This is windows smp client 5.91, stock box, no overclocking.

It's running the same WU again, now at 6%

Posted: **Thu Aug 14, 2008 8:53 pm**

I finally killed the client and moved off queue.dat and the work directory when it was running the same WU/PRG for the 4th time.

Of course, it assigned the same WU/CRG again, so I killed it again, and finally I got a different PRG, same project.

2665 (3, 165, 40) doesn't work. It gets a NaN every time at 19% on an unmodified AMD-based system with windows smp beta client 5.91

It's now running 2665(1, 377, 41). I hope this one completes.

Someone else completed Project: 2665 (Run 3, Clone 807, Gen 37) successfully ...

Same for Project: 2665 (Run 3, Clone 165, Gen 40).

@toTOW
Any idea on the client the other person used? I used 6.22 beta2 with the "SHM" fix.
Can you check this WU : Project: 2665 (Run 2, Clone 615, Gen 38)
[12:05:34] Completed 50000 out of 250000 steps (20 percent)
[12:14:16] Warning: long 1-4 interactions
[12:14:17] Gromacs cannot continue further.

I updated to R3 and it's at 7%.
I've done 13 units so far with the SMP client.
This was my second error so I don't think my machine is unstable.

Nobody has returned Project: 2665 (Run 2, Clone 615, Gen 38) yet. (this may be related to the delayed stats announced earlier today)

The data that the Mods can see doesn't tell us which client is being used. In any case, if 6.22b2-shm and 5.91 are probably both using the same version of Gromacs, and it's unlikely that the client version number matters when the Warning message is about a long 1-4 interaction.

@bruce
True, but if it was a random instability the second run could fix it.
I'm guessing here but if it was done on a linux client it could explain the fact it was completed (not sure what projects are done on the linux SMP clients).
If it fails again I'll try again.

UPDATE (August 21 21:10 UTC) : The unit finished successfully on the second run.
