Not getting quantum chemistry work

Well, looks like the above mentioned method didn't work, the first tasks I had some minutes ago errored out also. But obviously I made a mistake on searching the correct library over the Yast-installation, now I found gcc5, installed it and it finally seems to work, the current task already went over the "magic line" of 4-5 minutes! :-) That aside, I'm not sure if it's the VM but I notice a bit more HD activity and network connection since the task runs smoothly. Does it need data from your servers? |

Wow, thank you very much for that, wouldn't have found it. I tried to install that now. Not sure if it really worked, it gave me some dependency errors but the installation seemed to have worked somehow. Unfortunately I can't test if it works now, the faulty work units reduced my daily quota to 1 and I can't get any work for today anymore. Should have stopped it earlier, totally forgot it, ouch... |

Have you tried out: Tried that now, but also doesn't work. I only get "command not found". I guess this doesn't work with my old distribution anymore, I have openSuse 13.1 in a VM, and as far as I got aware, 13.1 is not supported anymore. |

I saw that there finally is enough work to start crunching on the quantum app, but it looks like there is something wrong with it, until now every wu crashes after some minutes. Example here. I'm not sure if the problem is on my side or yours. It seems like something is wrong with gcc-5-5, if I understand that right, but I can't update my system with that, seems not to be existent. |

Hi! I just saw that there are a few WUs of the Quantum Chemistry app are available and wanted to try them out on my Linux VM, but all I get is "no work from app". Though the amount of work is still visible on the server status and slowly decreasing, why can't I get any? Are they done internally? |

How to download 1 task?

Here comes V2.0 which extracts the path of the BOINC installation folder from the registry, so it will work without modification even if you've installed BOINC to a non-default path: Great, thank you! Will see if it works. If swan_sync would be in effect, then the CPU time & the Run time of your tasks would be the same. Ah, okay, didn't know that, but I see it when I compare it to your results. :-) |

How to download 1 task?

The problem is that the deadline of GPUGrid tasks is 5 days, while the quick return bonus is +50% for less than 24h and you want to achieve that on a near-miss GPU without reducing your work cache (time). Seems pretty impossible. Not really impossible, but yes, I have to admit that it's sometimes already going over the 24h-bonus, but there are still tasks which are doable. I see this with a very sad eye, because - and that goes a bit off topic now: About a year ago I bought this GTX760 to finally go into GPUGrid more intensively, while before I put it on hold because my died GTX660 had some problems with it. The work done as I started with the GTX760 was mostly done in 10-15 hours - getting the bonus with that was almost no problem. Over the months I noticed that the tasks need more and more time to finish, first 15-17, then 18-21, and now almost 24 hours. Since I cannot buy a highend-card and also cannot afford to buy a new graphic card every year only for that (and I don't want it of course, the money is needed somewhere else), the GTX760 should do the job as long as it can. If this continues and the WUs are getting longer again I soon can get no bonus anymore anyway, so my request is probably only for a short while. The batch file should look like this: Looks promising. Will try that later the day, thanks! You should also set the swan_sync environmental value to 1 to make your GPU crunch a bit faster by assigning a full CPU thread to the GPUGrid app (reduce the number of CPU tasks by at least 1) I'm not sure currently but I think I have swan_sync on already, have to look later. I have always reserved a core for GPU crunching per BOINC preferences anyway. I tried swan_sync already with the old GTX660, but there was no crunching difference with that, so I doubt that I need it, but I try it also... |

How to download 1 task?

Well, these tips aren't very helpful unfortunately, but thanks anyway. I don't want to change any settings on my cache or work distribution since changing it this drastically would definitely blow up my entire schedule, which is perfect currently. I thought there is a way to change the download amount client-side per xml-command or something. I'm a bit experienced in that stuff, but not enough to know the entire commands etc. Someone else any idea for this? |

Hi there! I'm always getting two tasks for my GTX760 but because of the length of the long WUs, it's rarely possible that my tasks are delivered "in time" to get the perfect bonus out of it, because when one is finished, uploaded, reported and the second one has just started crunching, there is already a new task downloaded. And this one then mostly starts crunching when the time for the best bonus is almost over. It would be better if I could get only 1 task to download and it should be exactly when the other one is finished, uploaded & reported - is that possible and how? Probably per cc_config or app_config-file? How this would need to look? |
