On our server just start new BHDB (Black Hole Database) application.
First work units release will be testing one, to check if everything is ok with application and points system :)

In near future we will publish more information about it.

Why do you keep cancelling the WUs at the server ?

Edit: is this why ?

I had cancelled two series because application store bigger temporary data files then was set in template file.
This is fixed now for number 3 batch.

The most recent ones have completed for me without error, and are awaiting validation.
https://universeathome.pl/universe/results.php?userid=2317&offset=0&show_names=0&state=2&appid=

These were run under Lubuntu 17.10.1 on a Ryzen 1700, which might make a difference. I will try my Haswell machine again shortly.

Just stopped sending new units from "3" batch, changed files size restriction bit higher and generated batch 4.
From third batch less then 10% units override file size limits from template.

I hope, some day we can use Black Holes and Quasars energy for our travels in Space. My be we will live on them some day. Yes, I know, it is a fantasy now, but iron ships was fantasy too many years ago. I hope DB BH and Q is useful now and can help us.

Are tasks from 3 OK? I just received some and some 4s. Of the 26 I downloaded, not a single one was an original task. None were _0, all were _2 to _4. What's this like the 4th-5th consecutive app so start off bad?

Please run some of these tasks yourself before releasing to us. There used to be a Universe Test project.

I'd like to support this project but the bad app released and tasks that never end w/o a fix after 2+ years make it hard to contribute.

Message 2642 - Posted: 9 Mar 2018, 23:49:35 UTC - in response to Message 2641.  

I leaved some "3" tasks to go on (the already sent ones) to check it.
I have used my 90+ threads (45 CPU cores with multithreading) on various machines to test it, but when 50+ tests are ok I sent it to server...

What I found just now, that on multi-thread CPU's (>16 threads e.g.) BM starts tasks and space allocated for WU's are filled at the time just before sending results to server (on my computer it was 99.995% of wu time).
This was not predictable before in oot of BOINC tests :(

On my Win7 the WUs break up around 60-70%.

My Diskspacelimit for Boinc is higher than the WUs needed....so it can´t be the problem. When i look into the Boinc-dir, /Slots....the files "Data1.dat2" and "Data1.dat3" go up to 3xx MB. Both files have the same size. Under Linux this files under 200MB and running fine to 100%.

Hmm, space required for this app is set to 900MB, so even if that both files grow to 400MB it should by not a problem (other files are small).

I just create another batch - 10 times smaller, just to see what happens (tasks will finish in about 7-10 minutes on fast machines).
