# MultiPar
|
|
|
|
v1.3.2.0 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.
