1. Boot up the kernel. The messages appear as follows:
...
Galcore version 6.2.4.163672
...
You will see GPU device filename as follows:
root@localhost:~# ll /dev/galcore
crw------- 1 root root 199, 0 Jan 28 2018 /dev/galcore
2. All the test cases are located under the /opt directory:
root@localhost:/opt# ls /opt
cl11 es20 tiger vdk
a. OpenCL demo
Below is FFT as example:
root@ localhost: cd /opt/cl11/fft
root@localhost:/opt/cl11/fft# ./fft 128
Block size: 16
Print result: yes
