Mosaic Pre-Run Checkout Procedure
Check VNCs
(1) check that VNC is running on both ctioa0 and ctioa8 (no need to restart them if they are already running). The commands and results should look like the following...
- ON ctioa0
mosaic@ctioa0% ps aux | grep vnc
| mosaic | 406 | 0.0 | 0.8 | 2244 | 2984 | ? | S | Apr 14 | 85:57 | Xvnc :9 -desktop X -http |
| mosaic | 408 | 0.0 | 0.0 | 36 | 0 | ? | IW | Apr 14 | 0:00 | /bin/sh /arc/mosaic/.vnc |
| mosaic | 11581 | 0.0 | 0.1 | 56 | 232 | pb | S | 11:33 | 0:00 | grep vnc |
- ON ctioa8
mosaic@ctioa8% ps aux | grep vnc
| mosaic | 6281 | 0.0 | 0.1 | 4304 | 2720 | pts/0 | S | 10:49 | 0:01 | Xvnc :9 -desktop |
| mosaic | 6541 | 0.0 | 0.2 | 6124 | 4568 | pts/0 | S | 11:00 | 0:11 | Xvnc :8 -desktop |
| mosaic | 7465 | 0.0 | 0.0 | 1728 | 592 | pts/7 | S | 11:23 | 0:00 | grep vnc |
Check PVMs
(2) check that pvm is working and correctly configured on both machines
- ON ctioa0
mosaic@ctioa0% pvm
pvmd already running.
pvm> conf
2 hosts, 2 data formats @@
| HOST | DTID | ARCH | SPEED |
| ctioa0 | 40000 | SUN4 | 1000 |
| ctioa8 | c0000 | LINUX | 1000 |
pvm> quit
pvmd still running.
- ON ctioa8
mosaic@ctioa8% pvm
pvmd already running.
pvm> conf
2 hosts, 2 data formats
| HOST | DTID | ARCH | SPEED |
| ctioa0 | 40000 | SUN4 | 1000 |
| ctioa8 | c0000 | LINUX | 1000 |
pvm> quit
pvmd still running.
If EITHER does not look like this, it is best to simply start from the beginning. This involves killing the pvm processes on BOTH ctioa0 and ctioa8 and then restarting them. To do this, follow the instructions on restarting the pvm.
Check out Arcon
Start up Arcon on ctioa0 and watch for errors in the Arcon Console window.
Also check the TCS and MSE boxes in the Mosaic GUI.
Check STB
Check data
- Noise in zero
- Gain and read noise
Check flat field lamps and counts
Confirm that counts listed on web page for given exposure times are approximately correct.
