# MultiPar
|
|
|
|
### v1.3.3.0 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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
