Great news! I have my machines attached, and signed up for beta testing. If this fix is successful, can/will it be applied to the OSX app? I seem to recall my Macs having the same problem. zombie67, all affected get their turn I'd expect.... it's a long running project so if efficiency improvement can be achieved or material inequity it will be taken care off. Work I'd do in order of materiality so given Linux is 3x bigger, suppose they are next in line to get applied what was/is being learned from the Windows code adjustments and betas. cheers PS, see knreed adding a note that the Linux Beta was send out prematurely and withdrawn, so now we know it's in the works as thought.

Oh happy day! I have one of these Beta tasks sitting in my queue, and I will report anything of interest later today.

Please do report in the Beta Forum. Opened a thread for that this morning.
----------------------------------------http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=18567 90% done it's looking good (for me on Vista it's actually same as before but running a little longer without a single PF Delta hit)

Just wondering.
Was beta testing performed on the first HCC work issues? If not, why not? |

Sorry, vaio, I don't quite follow your meaning.
HCC was beta tested before the project launched, and no critical issues were found. There were a couple of problems that were flagged for further attention, and if you remember, one of the bugs was serious enough that HCC on Linux was suspended for a while. |

I worded my post badly.
I was asking if it was beta tested before being released into the wild. Apparently it was so, fair enough. |

After the rocky launch experienced by HPF2, all new projects and all application updates go through the public beta process.

I can see how this problem would pass a beta test. It sits in a fringe few percent of the overall stats if you don’t run HCC exclusively. The issue though, when spread out over the grid, could be seen as significant if all in one place. For every 1% is 1000's of points and results in lost efficiency.
----------------------------------------The other side of this coin is still to be determined. The crashing of slower systems. This was common in memory challenged pc100 machines. I hope that with the current fix that this class will also see improvement. If not, just raise the minimum to 1gig for HCC. Then we will be out of the woods. No matter how you look at this, what has happened has peaked awareness of a problem and the techs have returned in kind. What this has shown is a key element between this being just a website full of geeks, to being a society that cares about itself. A society worth joining!     |

Thanks for the kind words, courine.
----------------------------------------I have had three betas running together in my new XP quad and everything went fine: page faults about 200,000, 40 MB in RAM and something about 150 MB of total VM. As it has always been, even during the page-fault time, HCC has the smallest memory requirement of the projects currently running at WCG. Therefore raising its requirement to 1 GB for whatever reason would be totally absurd. If you have older machines with little RAM HCC is the best project for them. On the other hand if they are running too slow for returning results in time it's a different problem which must be addressed for itself. I think that WCG's servers are able to take this into consideration once they have enough history for evaluating the profile of a given machine. If I am wrong another CA will probably correct me. Otherwise warn people with so slow machines that they are no longer worth the electricity that they are burning and that they would better stay away from this project. This too we are saying regularly in this forum, so people should not be disappointed. Cheers. Jean. |
