### ls-sycl-device
|
||
|
|
|
||
|
|
List all SYCL devices with ID, compute capability, max work group size, ect.
|
||
|
|
|
||
|
|
1. Build the llama.cpp for SYCL for all targets.
|
||
|
|
|
||
|
|
2. Enable oneAPI running environment
|
||
|
|
|
||
|
|
```
|
||
|
|
source /opt/intel/oneapi/setvars.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
3. Execute
|
||
|
|
|
||
|
|
```
|
||
|
|
./build/bin/ls-sycl-device
|
||
|
|
```
|
||
|
|
|
||
|
|
Check the ID in startup log, like:
|
||
|
|
|
||
|
|
```
|
||
|
|
found 4 SYCL devices:

|
||
|
|
Device 3: Intel(R) Arc(TM) A770 Graphics, compute capability 3.0,
|
||
|
|
max compute_units 512, max work group size 1024, max sub group size 32, global mem size 16225243136
|
||
|

|
|Attribute|Note|
|
||
|
|
|-|-|
|
||
|
|
|compute capability 1.3|Level-zero running time, recommended |
|
||
|
|
|compute capability 3.0|OpenCL running time, slower than level-zero in most cases|
