* Initial benchmark support.Andreas Grois2018-03-212-6/+22
| | | | Finally no more manual stopwatch usage...
* Fix build error regarding debug log clockv0.0.3½-speedAndreas Grois2018-03-181-1/+1
|
* Undo splitting of buffers in three. Makes buffer access much fasterAndreas Grois2018-03-182-27/+13
| | | | | Not kidding here. For the default parameters this increased the maximum pixel brightness in the image by a factor of 2.25. This has the drawback that the maximum possible image size got reduced, but hey, there's a command line switch to ignore all size limits ;-)
* Move totaliterations calculation to CPU. This frees 4 VGPRs.Andreas Grois2018-03-181-1/+4
| | | | | Now the code is back to the limit of 32 VGPRs without the need to directly operate on the state buffer. This means that now it's bound by memory access.
* Undo change to directly work on buffer. Causes about 30% slowdown...Andreas Grois2018-03-181-2/+3
|
* Add option to skip short orbits. Add option to print debug output.Andreas Grois2018-03-182-2/+20
|
* Adjust default workgroup sizes to better match recommended values.Andreas Grois2018-03-171-5/+5
| | | | AMD recommends a local workgroup size of 256.
* Properly calculate required buffer size. I'm starting to think that std140 ↵Andreas Grois2018-03-171-3/+8
| | | | would have been the better alternative...
* Fix memory allocation for state buffer. How could that ever work?Andreas Grois2018-03-171-1/+9
|
* Seems vec2 needs 16 bytes on nVidia...Andreas Grois2018-03-171-1/+1

* Improve parallelization by not storing the offset, but instead ↵Andreas Grois2018-03-171-1/+1

* Tweak PID a bitAndreas Grois2018-03-161-2/+2
|
* Fix endless loop in shader and make framerate adaptiveAndreas Grois2018-03-152-4/+21
| | | | | | It seems forcing points outside the cardioid and bulb with a bad random generator can take really long... Also, now framerate adjusts based on time it takes to render frames.
* Prevent even more waiting by storing a more complete stateAndreas Grois2018-03-151-1/+1
|
* Speed up computation tremendously, by having each worker (nearly)Andreas Grois2018-03-151-27/+2

* First commit with compute pausabilityAndreas Grois2018-03-142-12/+35

* Split buffer in three, one per color (as OpenGL guarantees that one can at ↵Andreas Grois2018-03-112-18/+33
| | | | | | | | least have 8 SSBOs), to allow three times larger images. Also make it possible to ignore maximum buffer size reported by the driver. The maximum buffer size limitation is rather strict on radeonsi, so I decided to split the buffer in three, effectively increasing the maximum image size by a factor of three. While doing so I realized that at least on radeonsi the reported maximum buffer size seems to be off. For this reason I added a new command line switch, that allows to ignore the maximum buffer size check. For those curious: radeonsi reports a maximum buffer size of 128 MB, but I had no problems when using three buffers of 1098 MB each.
