Bobrecki Post: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.119.075001 Are these relatively new findings have any impact on the ULX models we have computed?
2) Message boards : Number crunching : extreme long wu's (Message 2060) Posted 23 Mar 2017 by Sebastian M. Bobrecki Post: From beginning of march i have computed over 19k of task and only less than 3% have this issue. So for me it is not a big problem. Of course it will be good to have this fixed, but I remember times where projects that are bigger, with better financing and having opinion that they are stable have a lot bigger fail ratio.

Run it from cron for example every 5 minutes and voila.

5) Message boards : News : New QuarkStars application (Message 1288) Posted 2 Aug 2016 by Sebastian M. Bobrecki Post: Will there be another tasks for this application? Or maybe it was just a single shot?

8) Message boards : Science : Universe X-ray sources (Message 540) Posted 15 Sep 2015 by Sebastian M. Bobrecki Post: What's new/different with v3 application? Some tasks have name like "universe_xray_3_Paulina_...". Are they something special?
9) Message boards : Science : Typical evolutionary routes of EULXs (Message 429) Posted 20 Jul 2015 by Sebastian M. Bobrecki Post: Thank you for your explanation Grzegorz. If I understood it well, models shows that, IMBHs are not needed to create so bright sources. It also seems that in case of NS brightness can be even higher, but they will last a very short time (on a cosmic scale), which may hinder observation of such objects. I also have question, what exactly are the times in the charts 3 and 4? Is this the age of the galaxy model, the age of the system, or the time since ZAMS? P.S. Is it possible that predicted difference, about factor of 10 (NS: ~10^44 vs. BH: ~10^43), in maximum luminosity between systems with NS in relation to systems with BH, is a consequence of that most of the energy is absorbed by the BH?

11) Message boards : News : Work Units cancelled (Message 225) Posted 31 Mar 2015 by Sebastian M. Bobrecki Post: I have some task form 10 series, and it looks the same. 0% progress after ~40 minutes.

16) Message boards : Science : Universe X-ray sources (Message 156) Posted 12 Mar 2015 by Sebastian M. Bobrecki Post: What is difference between the old and new (v2) version of application? In addition to the obvious fact that the result files are smaller? Are we computing something different with it? Or maybe, it is just rejecting/losing/filtering some results?
17) Message boards : Science : Universe X-ray sources (Message 78) Posted 24 Feb 2015 by Sebastian M. Bobrecki Post: There's always that someone has to start, so... what exactly "Universe X-ray sources" application is doing?
