# MultiPar
v1.3.2.0 is public
### v1.3.2.3 is public
  This is a beta version to test new encoder & decoder.
I implemented a way of Cache Blocking for CPU's L3 cache optimization.
It will calculate multiple blocks at once on multi-Core CPU.
Old method calculated each block independently,
and could not avail the advantage of shared memory.
New method may use shared L3 cache more often, and will be fast on recent PCs.
  Thanks [prdp19 and Slava46](https://github.com/Yutaka-Sawada/MultiPar/issues/47) for many tests.
Thanks [Anime Tosho](https://github.com/Yutaka-Sawada/MultiPar/issues/21) for some idea and advice.
Also, other users aided my development.
Without their help, I could not perform this speed improvement.
  While new version seems to be faster on most cases,
it may happen to be slow for a few blocks.
Though I don't know the speed on old PCs, it may not become slow.
If you see a failure or strange result, please report the incident with ease.
I will try to solve as possible as I can.
  I adjusted CPU usage slider for CPUs with many Cores.
Now, each position will set different number of threads always.
Left most : 1/4 of CPU cores
One from left : 2/4 of CPU cores
Middle : 3/4 of CPU cores
One from right : 4/4 of CPU cores, or use one less threads on CPU with 6 or more Cores.
Right most : May use one more threads on CPU with 5 or less Cores.
  I improved calculating hash of multiple source files.
From my testing result, I changed default number of threads for NVMe SSD.
When you use a raid-system or external drive, it cannot detect the drive type.
If it fails to detect, it uses HDD mode by default.
At MultiPar options, it's possible to change the setting manually.
You may select one of them; HDD, SSD, or Fast SSD.
Caution, you should not select SSD, if your using drive is HDD.
  This is a minor update version.
Because some security vendors recognize MultiPar.exe's batch processing mode as stealth malware behavior,
I removed the "/batch command" feature.
Thanks [didamsko for reporting the problem and test](https://github.com/Yutaka-Sawada/MultiPar/issues/61).
If someone wants batch operation, please use command-line version par2j64.exe instead of GUI version MultiPar.exe.
[ Changes from 1.3.1.9 to 1.3.2.0 ]
[ Changes from 1.3.2.2 to 1.3.2.3 ]
GUI update
- Change
- Fast SSD is selectable as file access mode.
- Max number of log files was increased from 100 to 1000.
- CPU usage slider was adjusted on CPU with 6 or more Cores.
- Shadow of text over progress-bar becomes more smooth.
PAR2 client update
- Change
- Standard buffer size becomes double to decrease iteration.
- Single byte error in a single slice file may be corrected.
- Number of using threads was changed on CPU with 6 or more Cores.
- Enabling GPU won't use additional threads on multi-core CPU.
- Progress percent may move while writing blocks.
- Improvement
- L3 cache optimization was implemented for multi-core CPU.
Change
I removed /batch command from MultiPar.exe.
