1) Message boards : Number crunching : GPU not being used... (Message 2508) Posted 28 Nov 2017 by Rasputin42 Post: Because this Project does not have apps for GPU use. https://universeathome.pl/universe/apps.php
2) Message boards : Number crunching : Wrong type of app (Message 1551) Posted 11 Sep 2016 by Rasputin42 Post: The initial time estimate is waaay too low.(9 min instead of 5h) Therefore too many tasks are downloaded for any given work buffer. You should increase the estimated FLOP count for the tasks, to avoid that.
3) Message boards : Number crunching : Wrong type of app (Message 1546) Posted 10 Sep 2016 by Rasputin42 Post: How many tasks does it usually take? A 64-bit app has to be much faster.
4) Message boards : Number crunching : Wrong type of app (Message 1544) Posted 10 Sep 2016 by Rasputin42 Post: I have a 64-bit windows Computer, but appear to be getting 32-bit tasks. BHspin2_1_windows_intelx86.exe. The applications page states, that there is a 64-bit app. Why am i not getting any?
5) Message boards : Number crunching : Very high disk activity (Message 343) Posted 1 Jun 2015 by Rasputin42 Post: Thanks for recognizing the issue.I only noticed it, because i am using a usb flash drive for boinc.However, this continuous writing is especially bad for flash or ssd drives, in the long run.
6) Message boards : Number crunching : Very high disk activity (Message 336) Posted 31 May 2015 by Rasputin42 Post: These are the files, the 4 executables are constantly writing to. The rate of saved data NEVER falls below 25000 Bytes/sec. 4x (universe-xray_sources_v2_3_windows_intelx86.exe) Datei Write (B/s) -0 23.491 -0 18.736 -0 18.512 -0 16.665 G:\Boinc\ProgramData\BOINC\slots\9 13.377 G:\Boinc\ProgramData\BOINC\slots\11 11.277 G:\Boinc\ProgramData\BOINC\slots\10 11.133 G:\Boinc\ProgramData\BOINC\slots\12 10.097 G:\Boinc\ProgramData\BOINC\slots\9\tmp5467.dat 696 G:\Boinc\ProgramData\BOINC\slots\10\tmp5467.dat 588 G:\Boinc\ProgramData\BOINC\slots\12\tmp5467.dat 521 G:\Boinc\ProgramData\BOINC\slots\11\tmp5467.dat 405

8) Message boards : Number crunching : Very high disk activity (Message 333) Posted 31 May 2015 by Rasputin42 Post: I am using 7.4.42, the latest version, win 8.1 64 bit
9) Message boards : Number crunching : Very high disk activity (Message 331) Posted 31 May 2015 by Rasputin42 Post: Hi, It seems universe uses very little memory but extreme number of disk write activity. This strikes me as very very inefficient. Why don't you do this in memory and write the results to disk, instead of constantly having a large number of small data chunks being written to disk?
