So when did they start and do we have any more info.

I knew they were in the plans, but don't have any more knowledge.

Snagged my 1st one last

Snagged my 1st one last night, running on my i7. Its estimating 9 hours 25 mins to process. The All Sky GW ones are between 6 and 7 hours. Will have a better idea once its crunched it.

The initial estimate for the one I got and have now completed was accurate. Completed in ~6.5hrs on q6600 @3GHz.

It took the i7 8:41 to process it. One of my quaddies (Q6600 @ 2.4Ghz) got a bunch of them and they took 7:45 each.

I have one that's completed,

I have one that's completed, and has been unsuccessfully trying to upload for the last several hours. Yet, the regular Einstein workunits have been uploading okay. Has anyone else had this problem?

One ran in 7:30 on my stock

One ran in 7:30 on my stock (2.4 GHz) E6600 Conroe-generation host
Another ran in 6:22 on my stock Q9550 (2.83 GHz) (Penryn-generation)

I had one or two error out when I was not around for their first run. The firewall I run (Comodo) asks me to authorize first run of new executables. I don't know how long the period of grace is before it errors out, but it appears to be no more than a couple of minutes.

I returned several of them

I returned several of them already and they validated o.k. Although they take much longer (32,000 sec. vs. 25,000 sec. both on 8-core MacPro Nehalem 2.66) they receive much less credit (160 vs. appr. 189).

I detached them for now.

Yes, the credit inequality has been noted by another user as well, see the dedicated thread for this. The credits will be re-calibrated soon to get a better match between the two searches, stay tuned.

Thanks for reporting this
