Dear crunchers.

The project was developed a few years ago with an intern and a very limited budget. Despite many project submissions, we did not get any funding. Sometimes we are told that our project is too ambitious, sometimes not enough... It is discouraging! The truth is that the public funding of research in France is extremely low.

Our prototype programs are outdated. At the beginning, I struggled with VMs, then security changes in the Linux kernel started to prevent the application from running properly.

Despite everything and thanks to you (thank you!), we are coming to the end of a computing campaign and the integration of the data will take me a lot of time. The project is obviously not finished and we could still submit many calculations. But today the priority is to analyze and valorize what we already have. I'll go through the last calculations that had problems and see if I can resubmit some tasks, but very soon there will be no more WU.

We have made a lot of progress with little funding, we will continue to share our scientific publications with you. Moreover, we are currently finishing writing an article and I can already tell you that we have developed a way to greatly reduce the calculations of unstable molecules.

See you soon
Kind regards,
Benoit

hi,

the service provider say that problem on network should now be resolved.

Thanks

hi,

Murphy law is always in on modality!

Last year I did not went to holiday and all was fine.

This year I takes 15 days holiday to compensate the last years, and something goes wrong!

I leaved on 6 and the day 7 I got an email notification that my weather station (that every five minutes put online the collected data), was not online (it uses the same internet connection of the server).
However when I check the station and server connectivity from the cell all was fine.

But every days/few days, I got that the weather station was going offline for 2 to 8 hours, but always when I check it it was back online, so I suppose the station has some problem (maybe low internal battery).

When I come back last day, I see that weather station was ok, but I got no internet connection instead!

So it happens that for 15 days connection to server has some blackout (fortunately that was not for more that 8 hours in some days, so all can still get credits).

Now the service provider is investigated the issue, so if you get some hours of not connection to the server this is due for this problem that I hope will be fixed soon.

Thanks

I've been procrastinating in sharing some news and I finally got around to doing it.

My old thesis advisor who has been backing this project retired in May. I don't actually work for the university, so this means the project has lost is primary benefactor.

The good news is that the university has allowed the project to continue. The bad news is that they will not be supporting any more hardware upgrades. This means when the current hardware fails the project will come to an end.

I'm hoping the current hardware can last several more years. One of the most critical parts is the hard drive, and we just got a new one about 1.5 years ago. Given that the previous hard drive lasted over 4 years, this is a positive.

This news has played into my reasoning on the order of the searches. Given that sf3 is practically guaranteed to be complete, I though it was prudent to use our finite time to first concentrate on sf7. The short term goal is to get sf7 to the same state that sf3 is currently in, which should take us into early next year. At that point, we can either spend the time to finish off sf3 and sf7, or continue on with sf6. Doing sf6 will allow us to find more fields in the finite time we have left, but finishing off sf3 and sf7 will allow us to say with 100% certainty that they are indeed complete. I am leaning towards finishing off sf3 and sf7, but that may change as time goes on.
