Now to BOINC:


o Credit is awarded hourly for processing done within workunits.
o Workunits are placeholder dummies of non-defined duration with no required validation.
o Percentage progress can be ignored as is meaningless for tasks of non-defined duration.


And that's it! We hope you enjoy our project!



If you'd like more details keep on reading...


o DHE runs a Genetic Algorithm on your computer. These run for a non-defined time until a good solution is found. Hence "progress" within a workunit is meaningless and in fact workunits are dummies and do not represent actual work done.
o The DHE BOINC app will connect to our servers every 15 minutes and upload their progress. You can check how much you have made today (and yesterday) at: http://dhep.ga/statsdailyrankings.php. You can check how many of your cores are actively crunching by checking how many times your username (with spaces as _) appears at: http://dhep.ga/statstopology.php.
o Credit is awarded by a Validated Trickle system and is not awarded on workunit completion, because as mentioned above workunits are dummies. Hence you will receive credit by how much work is done within a workunit.
o Credit is awarded proportional to how much is contributed scientifically. This is roughly proportional to Ghz core/hours. So a core twice as fast will receive roughly twice the credit. Credit is awarded hourly.
o Restarting your BOINC client will show workunits resuming at 0%. This is normal and no work has been lost because you have already been awarded credit for all previous work done within the workunit. Remember the DHE BOINC app connects to our servers every 15 minutes to upload its progress. There is little value in having a percentage completion figure for a task with a non-defined processing time.
o All that said, workunits will occasionally end. This is when the goal at http://dhep.ga/statsgoal.php is changed which is roughly every two to four weeks.
o Computation Error will occasionally be the outcome of workunits. In most cases this is normal: when the server restarts with different class files the client will detect this through a NoClassDefFoundException. This will trigger the client to shutdown and restart as another WU to pick up the new class files.
o Workunits can be aborted at any time without any loss of progress or credit. However a Genetic Algorithm is more efficient when islands are connected continuously.
o Badges will be awarded and there are a variety of stats on which they will be based such as the number of times the Best of all Islands was arrived at on your island (aka 'Who's got the Knack'): all stats visible here: http://dhep.ga/statsrankings.php.
o You can also view live progress of the current run at http://dhep.ga/statsgoal.php and live genetic strains analysis at http://dhep.ga/statsstrains.php, and a list of GPL licenced results at http://dhep.ga/statstschof.php including an online circuit simulator to try them out.
o Any further questions may be answered at http://dhep.ga/faq.php and will be more than happy to help if not.

For some reason I am unable to attach DHEP on Linux Mint 19.1 for some reason.
Boincstats are set to attach project to the host, yet boinc manager is not downloading anything. If I try to add project manually boinc manager is freezing and I have to terminate app.

I tried boinctui as well but after typing in login credential nothing happens for about minute or so and 'Error' is displayed on top of the window.

Using boinccmd result in 'Authorization failure: -155'

Any clues?

boinccmd [--host hostname] [--passwd passwd] command
If you run boinccmd in the same directory as the BOINC client, you don't need to supply either a host name or a password.

Sounds like you may be running Boinccmd in a different directory to the boinc client?

boinccmd [--host hostname] [--passwd passwd] command
If you run boinccmd in the same directory as the BOINC client, you don't need to supply either a host name or a password.

passwd is rthe value in the gui_rpc_auth.cfg file.
