I wonder what this is all about, no info on the main page or beta and no graphics.

I've done a couple of these 2-year runs on a Linux box. They have 2 trickles but only one is shown on the task page, also 2 big yearly .zips.

It runs much slower (in Linux anyway) than hadcm3n_6.07; 0.88 s/Ts compared to 0.58 on the same setup, 66% slower.

Saw that the credit script had been running again and gave these ones 311 points, same as 6.07 for one trickle.
This has to be rectified for slowness
and only 1 trickle counted.

Yeah, I ran these fine on beta but trickles and credits stopped working sometime in March so I didn't know about these faulty things, well well..

There might be a bug somewhere. Usually the Run time and CPU time are close. On these WU, it's like: Run time(sec) 129,410.12 / CPU time (sec) 66.28! Wow, the CPU only worked 66 seconds!?
This might also explain the low cobblestones awarded...

This problem is under discussion among Moderators and staff. It has to do with when, in the process, the second .zip is generated. The clock gets reset and small CPU time covers what is done as the things are wrapped-up. (Thyme Lawn did great diagnostic work to sort things out.)

As best I can tell, both .zips are sent home and acknowledged properly. If that is correct, all is well and credits, et al, should be sorted out eventually.

Fortunately, CPDN credits are awarded per Trickle, not CPU time.

From the front page, I guess it's the http://www.climateprediction.net/projects/geoengineering/solar-radiation-management/, since it's the one that that uses HadCM3S.

Credit requires special scripts to be run, and this has apparently not happened recently.

And, it being a bank holiday in UK today, no one will be around to kick start the scripts till tomorrow morning at the earliest.
