# MultiPar
|
||||
|
||||
### v1.3.2.8 is public
|
||||
This is a minor update version to fix some bugs in rare cases.
|
||||
Most users don't see difference.
|
||||
If there is no serious problem in this version,
|
||||
next version will be the last of v1.3.2 tree.
|
||||
### v1.3.2.9 is public
|
||||
This is the final release of v1.3.2 tree.
|
||||
Because I want to public this as a stable version, I didn't change contents so much.
|
||||
PAR clients are same as previous version.
|
||||
Including long term used applications may be good to avoid false positive at Malware detection.
|
||||
|
||||
I fixed a [problem of MultiPar shell extension](https://github.com/Yutaka-Sawada/MultiPar/issues/86),
|
||||
when UAC (User Account Control on Windows Vista or later) is disabled.
|
||||
Thanks whulkhulk and Slava46 for test and confirm.
|
||||
If other users could not "Integrate MultiPar into Shell" ago, he may try this new version.
|
||||
I fixed a [compatibility issue in calling 7-Zip](https://github.com/Yutaka-Sawada/MultiPar/issues/92),
|
||||
which I didn't know the change.
|
||||
Thanks Lyoko-Jeremie for bug report.
|
||||
The incident happened, when a user selected many files.
|
||||
|
||||
I added a confirm dialog at closing MultiPar, when it's creating or repairing.
|
||||
This change may reduce accidental loss of working data.
|
||||
Though MultiPar inherits most usage and behavior of QuickPar, I would improve a bit.
|
||||
I made a sample feature to Save & Restore different "base directories".
|
||||
When you put PAR files in another folder from source files, it will set the previous directory automatically.
|
||||
Because this feature was tested little, it's disabled by default at this time.
|
||||
If you want to enable, add section `[Path]` on "MultiPar.ini".
|
||||
Then set `MRUMax` value, which is the maximum number of stored directries.
|
||||
You may set the value upto 26. It's disabled, when the value is 0.
|
||||
These two lines are like below:
|
||||
```
|
||||
[Path]
|
||||
MRUMax=5
|
||||
```
|
||||
|
||||
I fixed [small bugs in my OpenCL code for GPU](https://github.com/Yutaka-Sawada/MultiPar/issues/88).
|
||||
Though I'm not sure the incident, it might not work rarely.
|
||||
Because I don't use a graphics board on my PC, I didn't test myself.
|
||||
Thanks apprehensivemom for test.
|
||||
Even when you checked "Enable GPU acceleration", it may not use GPU for small data.
|
||||
It's because starting GPU is slow.
|
||||
If calculation finishes in a few seconds, using CPU only may be faster.
|
||||
GPU may require at least a few minutes task to see speed difference.
|
||||
As a note, I write its threshold below.
|
||||
|
||||
Threshold to use GPU:
|
||||
- Data size must be larger than 512 MB.
|
||||
- Block size must be larger than 64 KB.
|
||||
- Number of source blocks must be more than 256.
|
||||
- Number of recovery blocks must be more than 32.
|
||||
While I made MultiPar as an utility tool, I didn't give priority to its speed.
|
||||
If someone wants faster Parchive tool, I suggest to use ParPar tools instead of MultiPar.
|
||||
They are "[High performance PAR2 create client for NodeJS](https://github.com/animetosho/ParPar)" or
|
||||
"[speed focused par2cmdline fork](https://github.com/animetosho/par2cmdline-turbo)".
|
||||
Though the speed depends on hardware environments and user's setting, it would be 50% ~ 100 % faster than my par2j.
|
||||
Only when you have a very fast graphics borad, GPU enabled par2j may be faster.
|
||||
I plan to improve speed of par2j in next v1.3.3 tree.
|
||||
Though it will become 20% ~ 30% faster than old par2j, ParPar would be faster mostly.
