KAGRA/Subgroups/DGS/RTPC/SNS/DirectoryStructure

Directory structure for Small Network System (RTS2.5.2)

Directory in master PC for master itself and slave (k1tst1, k1tst2) for PXE boot

master: / (root)
k1tst1 and k1tst2: /diskless/root on master booted by PXE
- /diskless/root will be mounted to / (root) on k1tst1 and k1tst2
- /opt/rtcds on k1tst1 and k1tst2 are NFS mounted to /opt/rtcds on master
- /opt/rtapps on k1tst1 and k1tst2 are NFS mounted to /opt/rtapps on master
- /home/controls on k1tst1 and k1tst2 are NFS mounted to /home/controls on master
- /usr on k1tst1 and k1tst2 are NFS mounted to /usr on master

Mainly of master

/opt/mx: mx (Mirynet) directory for master
/opt/rtcds/tst/x1/target/fb/ : mainly setting for daqd, nds.
- /opt/rtcds/tst/x1/target/fb/daqdrc : a setting file for daqd.
- /opt/rtcds/tst/x1/target/fb/master : a setting file to call channel information.
- /opt/rtcds/tst/x1/target/fb/logs/ : log files for daqd and nds.
- /opt/rtcds/tst/x1/target/fb/jobs/ : working directory for nds.
master has no /etc/rc.local
/etc/conf.d/local.start : to start 'ntpdate', 'ntpd', 'caRepeater', 'symmetricom', 'dis_networkmgr'.
/etc/inittab : to start 'nds' and 'daqd(mx)'.
/etc/xinet.d/ : setting files to start 'diagconf', 'chnconf' and 'leapconf'.
- /etc/service : to start diagconf.
- /etc/rpc : to start chnconf and leapconf.
/etc/export : for NFS export
/opt/rtapps/ : additional application folder to run RTS: epics, fftw, framecpp, gds, lib frame, mebmetaio, root, rtapps-user-env.sh.
/opt/rtcds/rtscores/ : Including all advLigoRTS svn structure until 2.6.1. Under tags or branches folders, each folder includes Makefile to build nds and daqd.
- To build nds,j ust type
```
>make nds
```
  under /opt/rtcds/rtscores/ and copy build/nds/nds to /opt/rtcds/tst/x1/target/fb/ (use 'ls -s daqd.xxx daqg' if you want to keep old versions).
- To build daqd
```
>make mx
```
  under /opt/rtcds/rtscores/and copy build/mx/daqd to /opt/rtcds/tst/x1/target/fb/ (use 'ls -s daqd.xxx daqg' if you want to keep old versions).

Mainly for slave (k1tst1, and k1tst2)

/opt/open-mx: open mx directory for slave
/opt/DIS: Dolphin reflective memory directory for slave
/opt/srcdis
/opt/rtcds/rtscores/
- Including all advLigoRTS svn structure until 2.6.1. Under tags or branches folders, each folder includes Makefile to build RT models, awgtman , mbuf etc.
- To build RT model, longin to k1tst1 or k1tst2 (probably master is also OK), change directory to version you need, and just type
```
> make x1x14
> make install-x1x14
> make x1vex
> make install-x1vex
```
  to start the new model, you MUST login k1tst1 or k1tst2 which you run the model
```
> killx1vex
> startx1x14
> startx1vex
```
  k1tst1 has x1x14, x1x15, and k1tst2 has x1x16, x1x17, x1x18(2013/3/5). To build awgtpman cd src/gds and type
```
>make
```
  , To build mbuf cd src/drv/mbuf and type
```
>make
```
Each RTS folder under /opt/rtcds/rtscores/tags/ or /opt/rtcds/rtscores/branches/ includes
- src/epics/simLink/
  - .mdl (RT model) files. Matlab opens these model files.
- src/epics/simLink/lib/
  - library for RT models with Matlab. Needs to path at the beginning when Matlab open .mdl files.
/opt/rtcds/tst/x1/scripts : script files to restart/kill RT models. To start an RT model, you MUST login k1tst1 or k1tst2 which you run the model, and type
```
> startx1x14
```
for example. This commands can be run in any directory since path is set in .bashrc in /home/controls.
/opt/rtcds/tst/x1/target/gds/
- /opt/rtcds/tst/x1/target/gds/bin/ : binary file of awgtpman.
- /opt/rtcds/tst/x1/target/gds/awgtpman_startup/ : startup scripts for awgtpman, called from startup script of each model.
- /opt/rtcds/tst/x1/target/gds/awgtpman_logs/ : log files for starting awgtpman.
- /opt/rtcds/tst/x1/target/gds/param/ : detail of testpoint channels. testpoint.par is automatically produced.
/opt/rtcds/tst/x1/target/x1x14/ etc.
- /opt/rtcds/tst/x1/target/x1x14/scripts etc. : to load epics IOC, RT kernel module, awgtpman. Called from /etc/rc.local.
- /opt/rtcds/tst/x1/target/x1x14/x1x14epics etc. : to start epics ioc. Called from startup script of each model.
/opt/rtcds/tst/x1/medm/ : for medm .adl files, used by medm.
/opt/rtcds/tst/x1/chans/ : digital filter setting files, used by foton.
/opt/rtapps/ : additional application folder to run RTS: epics, fftw, framecpp, gds, lib frame, mebmetaio, root, rtapps-user-env.sh.
/etc/rc.local : to start 'caRepeat', 'mbuf', 'load_dolphin_drivers.sh', 'omx', 'dxconfig', 'dis_nodemgr', 'mx_stream', 'gen_awgtiman_script.sh', 'monit'.
- /etc/rtsystab : includes name of RT models to be run.
/etc/fstab : mount for diskless root etc.
/lib/modules/2.6.34.1/kernel/drivers/mbuf/ : location of mbuf module 'mbuf.ko'. Called from /etc/rc.local.
