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, 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, 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.
