Ok, thank you. I visited Dispatch from multiple Linux processes — TI OpenCL User's Guide and found out that I do not have ti-mct-daemon.service which should be /lib/systemd/system/ti-mct-daemon.service . Does it mean that OpenCL just doesn’t work and I should create such a file? Then what should be inside it. Also I do not understand how to kill ti-mctd process and then restart it because when I write ./ti-mctd systems responds that file does not exist.
