# MultiPar
### v1.3.3.0 is public
### v1.3.3.1 is public
  This is a testing version to improve speed of PAR2 calculation.
Because the new method isn't tested so much, there may be a bug, failure, or mistake.
@@ -9,60 +9,55 @@ When you don't want to test by yourself, you should not use this yet.
If you see a problem, please report the incident.
I will try to solve as possible as I can.
  The PAR2 calculation speed may be 10% ~ 50% faster than old version.
The optimization depends on hardware environment.
I don't know what is the best setting on which PC.
From [many tests of debug versions](https://github.com/Yutaka-Sawada/MultiPar/issues/99),
it will select maybe better setting automatically.
Thanks testers for many trials.
If you want to compare speed of different settings on your PC, you may try those debug versions.
  CPU's L3 cache optimization depends on hardware environment.
It's difficult to guess the best setting for unknown type.
It seems to work well on Intel and AMD 's most CPUs.
Thanks Anime Tosho and MikeSW17 for long tests.
But, I'm not sure the perfomance of rare strange kind CPUs.
If you want to compare speed of different settings on your CPU,
you may try samples (TestBlock_2023-08-31.zip) in "MultiPar_sample" folder
on [OneDrive](https://1drv.ms/u/s!AtGhNMUyvbWOg0cF2UHcs709Icv4).
  I changed GPU implementation largely, too.
To adopt CPU optimization, it will process smaller tasks on GPU.
Because GPU don't use CPU's cache, it's inefficient for GPU's task.
I don't know that new method is faster than old version or not.
  I improved GPU implementation very much.
Thanks [Slava46 and K2M74 for many tests](https://github.com/Yutaka-Sawada/MultiPar/issues/99).
While I almost gave up to increase speed, their effort encouraged me to try many ways.
Without their aid, I could not implement this GPU function.
OpenCL perfomance is varied in every graphics boards.
If you have a fast graphics board, enabling "GPU acceleration" would be faster.
If it's not so fast (or is slow) on your PC, just un-check the feature.
Threshold to use GPU:
- Data size must be larger than 200 MB.
- Block size must be larger than 64 KB.
- Number of source blocks must be more than 192.
- Number of recovery blocks must be more than 8.
  Because [a user requested](https://github.com/Yutaka-Sawada/MultiPar/issues/102),
I implemented a way to add 5th item in "Media size" on Create window.
Write this line `MediaList4=name:size` under `[Option]` section in `MultiPar.ini`.
Currently, you cannot change the item on Option window.
  I saw a new feature of Inno Setup 6, which changes install mode.
It shows a dialog to ask which install mode.
Then, a user can install MultiPar in "Program Files" directory by selecting "Install for all users".
This method may be easier than starting installer by "Run as administrator".
I test the selection dialog at this version.
If there is no problem nor complaint from users, I use this style in later versions, too.
[ Changes from 1.3.2.9 to 1.3.3.0 ]
[ Changes from 1.3.3.0 to 1.3.3.1 ]
GUI update
- Change
- Option adapted to new "lc" settings.
- It's possible to add 5th item in "Media size" on Create window.
Installer update
- It shows dialog to select "per user" or "per machine" installation.
PAR2 client update
- Change
- Max number of using threads is increased to 32.
- Threshold to use GPU was decreased.
- Max number of threads to read files on SSD was increased to 6.
- Improvement
- Matrix inversion may use more threads.
- L3 cache optimization was improved for recent CPUs.
- GPU acceleration would become faster.

  To install under "Program Files" or "Program Files (x86)" directory,
you must start the installer with administrative privileges by selecting
"Run as administrator" on right-click menu.
you must select "Install for all users" at the first dialog.
