Hi!

Maybe this is wrong, but I do not want to release new WUs (which are not really needed for our research) just to keep volunteers busy and attached to the project.

We have finished revision of our paper and sent it for the second review round. Now, we wait for the results. Therefore, most probably there will be no new WUs within the next couple of months.

Next, depending on the success we will need to discuss within our group whether or how to proceed with the current application. I remind that the current application is the result of collaboration between two departments of our university.

Currently, I have a proposition to deploy to the public project another application developed by master student on our private BOINC project. It is searching for Proth prime numbers. Maybe I am wrong again, but I am reluctant to do that. Personally, I don't see scientific value in such application.

Regards

Dear VGTU project@Home users,

We have decided to stop the computations with the current application for grillage optimization. Some results have been obtained. We have prepared and submitted according publication, which is currently under review. However, new ideas are needed to move forward.

Now, we stop the generation of new tasks and wait for all results to return back to the project server.

Next, we will update the server software to support GDPR - the European General Data Protection Regulation.

We thank you for active participation and wish you a Merry Christmas and a Happy New Year!

With best regards,
The Project Team

I appreciate your support, but we need to wait for the results of peer reviewing.

Fixing current minor and major issues, we are preparing a new application version. We will also try to check whether something can be done with optimization options.

Hi,

I have found your result file on the upload server. Due to some reason it was corrupted. I have deleted it and correct file was received on 9 Apr 2018, 8:54:37 UTC.

Something is wrong with your client. Please note that almost all tasks have not been started properly.

You should see in Stderr output something like:

06:15:50 (133002): Starting client application!
06:15:50 (133002): Reading input file...

Have you experienced similar problems with other projects?

First, we need to find out what is wrong with that task and eliminate the bug or error in the algorithm. This is important also from the scientific point of view. We will also rethink our validation procedure.

Thanks again.

Yes, the problem is within the task itself. This is the first time I see it. Thank you for pointing it out. We will study it and think on necessary changes to validation of the results.

I have granted the credits for this task.

Dear VGTU project@Home users,

We are constantly working on the current research problem.

Although, you don’t see changes in the client applications (versions are the same), generation of work and assimilation/processing of the results are changed from time to time.

After one of such changes, the bug was introduced into generation of tasks (workunits). We believe that we have fixed this bug in work generator on Monday, March 12. It seems that there are no problems with the tasks/workunits generated since then. However, some older erroneous work units may still be there… We don’t know exactly which to cancel them. Don’t worry, no time is lost: application simply fails to start and generates ERR_TOO_MANY_EXITS error after some number of trials.

The good news is that we have started to write a draft of the paper on the current research using our BOINC project.


With best regards,
The Project Team.

Hi,

No, no news on this topic. :-)

I know that users would really like to see project's developments like OSX, GPU application versions, badges and so on…

But I hardly have time to properly test all current developments. I’m surprised that nobody is complaining about the huge number of errors in the recent days due to the bug in a new version of work generator… We have fixed it on Monday. However, some erroneous work units may still be there… I don’t know exactly which to cancel them. Don’t worry, no time is lost: application simply fails to start.

The good news is that we have started to write a draft of the paper on the current research using our BOINC project.

Our current application is not using replication, when two tasks are sent for each workunit. We are sending only one task for each workinit.

The server 'gives up' on the not returned task and generates a new task of the same work unit, to be assigned to another client.

After this new task has been solved and returned back to the server then, even if the first task is returned, it receives the status "Task was reported too late to validate [5]" and credits are not granted.

OK, here is more information. Current problem of grillage optimization cannot be solved with some final number of WUs and closed. And the goal is not to solve the problem. We use it as so called “benchmark problem” for development and testing of parallel global optimization algorithms. Currently, we solve the problem with 55 unknowns using parallel genetic algorithm. We are testing the performance of algorithm and its modifications with different parameters.

After 2-3 months, we plan to implement and start testing algorithm based on Simulated annealing (global optimization technique). Using the results obtained on BOINC and HPC clusters, we are planning to prepare 1 or 2 publications.

So, this is the plan for the next 6 month.

Afterwards, depending on the results, we may continue with the current problem or move to some new problem, as has happened already several times in our project.

Yes, we have plans to introduce badges to our project. However, development of current application has the highest priority at the moment.

This may be complecated. Try to check your network settings, firewall.

Read also this thread:

In short, try to change http_1_0 parameter in cc_config.xml.
