"The CLBlast ffi" is a interface for the CLBlast library. Available in libraries with FFI interface.
10+
11+
Please see the documents about Buffer objects on [Rindow Mathematics](https://rindow.github.io/mathematics/acceleration/opencl.html#rindow-clblast-ffi) web pages.
12+
13+
Requirements
14+
============
15+
16+
- PHP 8.1 or PHP8.2 or PHP8.3
17+
- CLBlast 1.5.1 or later
18+
19+
How to setup OpenCL & CLBlast
20+
=============================
21+
You can download and setup pre-built CLBlast binaries.
22+
Please download the binaries for your platform.
23+
24+
- https://github.com/CNugteren/CLBlast/releases
25+
26+
27+
### Windows
28+
CLBlast and OpenBLAS DLL's path to Windows PATH environment variable.
29+
30+
```shell
31+
C:\tmp>PATH %PATH%;/path/to/OpenBLAS/bin;/path/to/CLBlast-Library/lib
32+
C:\tmp>cd /some/app/directory
33+
C:\app\dir>composer require rindow/rindow-clblast-ffi
34+
```
35+
36+
### Ubuntu
37+
On Linux, you first need to set up OpenCL.
38+
39+
For example, in the case of Ubuntu standard AMD driver, install as follows
40+
```shell
41+
$ sudo apt install clinfo
42+
$ sudo apt install mesa-opencl-icd
43+
$ sudo mkdir -p /usr/local/usr/lib
44+
$ sudo ln -s /usr/lib/clc /usr/local/usr/lib/clc
45+
```
46+
Ubuntu standard OpenCL drivers include:
47+
- mesa-opencl-icd
48+
- beignet-opencl-icd
49+
- intel-opencl-icd
50+
- nvidia-opencl-icd-xxx
51+
- pocl-opencl-icd
52+
53+
54+
Next, download and set up clbast.
55+
56+
Download and Extract Archive file and Pack to deb
57+
```shell
58+
$ cd /some/app/directory
59+
$ composer require rindow/rindow-clblast-ffi
60+
$ cp vendor/rindow/rindow-clblast-ffi/clblast-packdeb.sh .
61+
$ sh ./clblast-packdeb.sh
62+
$ sudo apt install ./clblast_X.X.X-X+ubuntuXX.XX_amd64.deb
63+
```
