# Render Group and Rebooting
|
||
|
|
|
||
|
|
When trying to do a hardware shutdown, I got these error messages for every instance
|
||
|
|
of the `clinfo` process that I had started up. They hang hard, and don't respond to
|
||
|
|
kill signals.
|
||
|
|
|
||
|
|
```
|
||
|
|
systemd-shutdown[1]: Waiting for process: clinfo, clinfo, clinfo, clinfo, clinfo
|
||
|
|
```
|
||
|
|
|
||
|
|
## Rebooting
|
||
|
|
|
||
|
|
New groups indeed show up upon reboot.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ id
|
||
|
|
uid=1000(arcologos) gid=1000(arcologos) groups=1000(arcologos),4(adm),24(cdrom),27(sudo),30(dip),44(video),46(plugdev),109(render),120(lpadmin),133(lxd),134(sambashare)
|
||
|
|
```
|
||
|
|
|
||
|
|
## Killing `clinfo` Process
|
||
|
|
|
||
|
|
Repeatedly calling
|
||
|
|
|
||
|
|
```
|
||
|
|
ps -eax
|
||
|
|
```
|
||
|
|
|
||
|
|
and
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo kill -KILL <pid>
|
||
|
|
```
|
||
|
|
|
||
|
|
of anything mentioning `clinfo` eventually did kill the `bash` processes
|
||
|
|
waiting on `clinfo` after many minutes. However, the real processes
|
||
|
|
remain as zombies
|
||
|
|
|
||
|
|
```
|
||
|
|
$ ps -eax | grep clinfo
|
||
|
|
1519 pts/0 D 0:44 [clinfo]
|
||
|
|
1553 pts/1 D 0:00 [clinfo]

## Installing `libnuma-dev`
|
||
|
|
|
||
|
|
One of the GitHub issue advice was to install `libnuma-dev`,
|
||
|
|
and now I wish I had been paying more attention to NUMA when
|
||
|
|
working on SaLSa self-driving cars with Samhitha.
|
||
|
|
|
||
|
|
```
|
||
|
|
$ sudo apt install numactl
|
||
|

The two cores of the Celeron show up in `numactl` but not the GPU.

$ sudo numactl -s

## Perhaps a Problem with `rocm-opencl` or Ubuntu distribution.
|
||
|
|
|
||
|
|
A problem with this on Fedora prompts `clinfo` maintainer to suggest taking it up with Fedora
