Dear users, we are submitting several WUs (*EGF*) directly related with colorectal cancer research. We are collaborating with MDs & researchers at the Hospital del Mar here in Barcelona to characterize some previously unreported effects of a well-known drug for cancer. Thanks for your precious contribution. | |

Are these short, long or beta Wu's? | |

I'm currently processing a p27-IBUCH_4_wtEGF_110726-0-10-RND2134_1 WU, which is a long one. | |

I've got another piece of this very rare kind of long WU: p36-IBUCH_2_wtEGF_110726-0-10-RND6674_1 | |

Hi, I have also tried one of these tasks lately, are longer and less credit. Greetings. | |

Application: Long runs (8-12 hours on fastest card) | |

Application: Long runs (8-12 hours on fastest card) I'm not complaining about the running time, I wanted to say "at long last!" But when this running time will become frequent, I have to reduce my task queue length, if I don't want to miss the 24h bonus. (and many others will have to do it too) Anyway, it might take 12h exactly on a GTX580 optimized under Linux-x64. Venec's Linux host completed two of these: p10-IBUCH_4_cetumutEGFR_110912-0-10-RND9933_0 13h p1-IBUCH_4_cetumutEGFR_110912-0-10-RND6052_0 13h04m My (overclocked) GTX580 finished just as it was predicted: p47-IBUCH_2_cetumutEGFR_110912-0-10-RND9228_0 12h45m There are many different task types so there will be variety in run lengths, and they don't all fit the same performance/credit scheme due to differences in the calculations and amount of CPU usage. Of course, but it would have been great to read about these really long workunits in the news section before they strike me (and others) with their running time. Anyway, I did posted about them to welcome their length, and also to warn the others about it. | |

I share your concern about task lengths, after seeing several tasks take over 1day on a GTX260. However having a low cache has always been recommended for GPUGrid. Perhaps this time some notice would have been useful as these are so long but I am not sure we generally need an announcement every time a task has a different length. If we do then we need a table of different task types and expected completion times for different cards on different systems (XP or Win7). That would require a lot of maintenance. | |

Perhaps this time some notice would have been useful as these are so long but I am not sure we generally need an announcement every time a task has a different length. As I see this, in one end there are the enthusiast crunchers, who will adopt to anything the project they are crunching for will require without any communication from the project personnel. In the other end, there are the common crunchers, who like to be treated like a part of a community they are crunching for. I understand, that this project is more for the enthusiasts, than the common crunchers, but even an enthusiast like me likes to be treated as a part of a community from time to time :) So I think I would like to have announcements about new task types, even if it's only a single sentence. If we do then we need a table of different task types and expected completion times for different cards on different systems (XP or Win7). That would require a lot of maintenance. Good idea. I was about to recommend something like that. It wouldn't have to be complete, but it's a good basis for checking the performance of someone's system. | |

I think that the idea of Ignasi was to announce the new project EGF, not every single batch that it is put online for that project. Of course, this can be done as well. It should not require too much time. | |

Hello: I just finished one of these tasks (p20-IBUCH_5_cetumutEGFR. ..) on my GTX295 in more than 27 hours. | |

...It wouldn't have to be complete, but it's a good basis for checking the performance of someone's system. It should be possible to create a calculation for this, so that people could enter their GPU and work out how long a task should take; the GFlops peak are static constants. So with a known task type and given steps someone could create a calculator to display this. You could even account for OC/UC'ing, as this has a linear influence. Hello: I just finished one of these tasks (p20-IBUCH_5_cetumutEGFR. ..) on my GTX295 in more than 27 hours. This is my concern. A high end (GTX200 series) GPU taking over 24h to complete a task. It's too long to claim the 50% bonus. If I had known a few weeks in advance I might have even sold my GTX260 and replaced it with a Fermi, so that I could finish said tasks within 24h. All that said, I'm sure Ignasi did not mean to create tasks that would not return within 24h or 12h for respective GTX200/GTX500 series GPU's, and there are limited numbers of these Looong Cancer tasks, so I don't want to bang on about it. In fact, as Zoltan said, I'm happy to see them in the Long format, if that helps, and I will adapt accordingly. Good luck, | |

Presuming appropriate optimizations/recommended settings are in place, and stock cards. | |

My XP machine with a GTX 285 card without the SWAN_SYNC 0 finished in 86,172.64 seconds or just under 24 hours. | |

After looking at a few tasks I think the chart might be out by about 27% for the GTX200 series cards. I will correct it below. | |

Should we abort the *cetumutEGFR* tasks? | |
ID: 22103 | Rating: 0 | rate: / Reply Quote | |
Abort them if they haven't started or you don't want to keep crunching them. | |

I am submitting *1_cmEGFR* only 51 WU literally half as long. Confirm that you see the reduction please and I'll submit the 200 remaining for this calculation. I got one running on my slowest GTX480 for 1h47m21s and it's at 27.376%, so it'll take 6h32m to complete. | |

Hi criadoperez, thanks for completing the very long task. | |

I've read about this research, and I wonder if GPUGrid can help in its progress. If your method is applicable, do you plan to (or are even allowed to) contribute to this research? | |

I've read about this research, and I wonder if GPUGrid can help in its progress. If your method is applicable, do you plan to (or are even allowed to) contribute to this research? It's certainly a very nice piece of work. In theory, one could simulate all the chemicals, the transporter, the membrane, (not the milk I am afraid) and try to visualise and measure the binding and competition process that they describe. In practice it is not feasible yet: 1) AFAIK, the structure of the transporter protein (NIS) isn't solved. This means that we don't know how its atoms are arranged in space (a requirement for molecular simulations). Alternatively, one has to build homology models which is like doing "patchwork", trying to reconstruct an unknown structure, from already known structures with which it shares a fair amount of amino-acid (subunits of proteins) sequence similarity. This, in itself is another field of study and a large amount of work unrelated to molecular simulations. Preferably, we always work with experimentally-determined (solved) structures for a start. 2) AFAIK, breast milk hasn't been really modelled yet as a solvent for molecular simulations. We should add to the existing water models all components of milk. Right now, physiologic type of simulations containing water only include sodium chloride (salt) or other ions/types of salts. 3) The timescales of the transport for the chemicals is way too slow for the computation times we can afford. The plot in this figure shows the curves (concentrations) of the chemicals in their test. If you see the timescale of the exchange is of the order of hours. Currently the slowest molecular process that we can simulate and measure using GPUGRID is of the order of several microseconds. Personally, I don't think we are ready yet to handle such system/process using molecular dynamics simulations. Thanks for the interest! | |

WRT the structure of the NIS protein, I found a description of the Putative | |

Indeed. Nice contribution skgiven. Predicting secondary structure is pretty straightforward nowadays. But as you say, unfortunately not enough to understand its tertiary structure in the membrane. Let me emphasize that transmembrane (insoluble) proteins are typically the hardest structures to solve. Have a nice weekend, | |

I've read about another interesting publication. I think it's closer to the timescales of GPUGrid. | |
