# MultiPar
|
|
|
|
### 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.
|
|
Be careful to use this non-stable version.
|
|
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.
|
|
|
|
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 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.
|
|
|
|
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.
|
|
|
|
|
|

To install under "Program Files" or "Program Files (x86)" directory,
|
|
you must select "Install for all users" at the first dialog.
