====== New images pwstudiocpu pwstudiogpu ======

<WRAP center round todo 10%>
The new images do not support CentOS 7.9
</WRAP>

**Must read for this chapter:** To use the new images, simply replace qflow with pwstudio in the image-import step and the container-start step of the corresponding tutorial. For example, replace qflowgpu:latest with pwstudiogpu:latest, and qflowcpu:latest with pwstudiocpu:latest
----

===== Check the PWmat version =====

<code bash>
docker run ccr.ccs.tencentyun.com/lxkt/pwstudiocpu PWmat -v
</code>

===== Linux: start the pwstudiogpu container =====

<code bash>
docker run -d --name pwstudiogpu \
  -v /var/tmp/pwmat_host_secret:/var/tmp/pwmat_host_secret:ro \
  --ulimit memlock=-1:-1 --ulimit stack=-1:-1 \
  --gpus all --shm-size=128G --privileged -e SELINUX=disabled \
  -p 80:80 -p 81:81 -p 2297:2297 -p 5010:5010 --hostname=mstation \
  ccr.ccs.tencentyun.com/lxkt/pwstudiogpu:latest
</code>

===== Linux: start the pwstudiocpu container =====

<code bash>
docker run -d --name pwstudiocpu \
  -v /var/tmp/pwmat_host_secret:/var/tmp/pwmat_host_secret:ro \
  --ulimit memlock=-1:-1 --ulimit stack=-1:-1 \
  --shm-size=128G --privileged -e SELINUX=disabled -p 80:80 -p 81:81 -p 2297:2297 -p 5010:5010 \
  --hostname=mstation ccr.ccs.tencentyun.com/lxkt/pwstudiocpu:latest
</code>

===== Linux: start the pwstudiogpu container, keeping data (including qflow) =====

<code bash>
docker run -d --name pwstudiogpu \
  -v /var/tmp/pwmat_host_secret:/var/tmp/pwmat_host_secret:ro \
  -v /root/vol/pwmat:/share/home/pwmat \
  -v /root/vol/mysql:/var/lib/mysql \
  --ulimit memlock=-1:-1 --ulimit stack=-1:-1 \
  --gpus all --shm-size=128G --privileged -e SELINUX=disabled \
  -p 80:80 -p 81:81 -p 2297:2297 -p 5010:5010 --hostname=mstation \
  ccr.ccs.tencentyun.com/lxkt/pwstudiogpu:latest
</code>

===== Host machine, user user01, keeping data (including qflow) =====

> The pwmat user inside the container has uid/gid 1000/1000
> The user01 user on the host machine has uid/gid 1001/1001 (not 1000/1000)
> /home/user01/vol/pwmat is the directory to mount, extracted from pwmat.tgz: the pwmat home directory inside the container
> /home/user01/vol/mysql is the directory to mount, extracted from mysql.tgz: the database
>
> user01 can also be left without read/write permission to pwmat (pure qflow, no modifications needed)

<code bash>
# Grant user01 the permission directly
setfacl -R -m u:1001:rwx /home/user01/vol/pwmat

ls -ln /home/user01/vol/
drwxr-xr-x 7   27   27 4096 Aug 17 17:11 mysql
drwx------ 4 1000 1000   91 Aug 17 14:48 pwmat

docker run -d --name pwstudiogpu \
  -v /var/tmp/pwmat_host_secret:/var/tmp/pwmat_host_secret:ro \
  -v $HOME/vol/pwmat:/share/home/pwmat \
  -v $HOME/vol/mysql:/var/lib/mysql \
  --ulimit memlock=-1:-1 --ulimit stack=-1:-1 \
  --gpus all --shm-size=128G --privileged -e SELINUX=disabled \
  -p 80:80 -p 81:81 -p 2297:2297 -p 5010:5010 --hostname=mstation \
