Comments:
This is an eVLBI experiment. No disks are needed!!!!
Connect DAS directly to VSIC
Running evlbi software
vsib_record must be run at by hand currently. Log onto each recorder as vlbi and run the command
> vsib_record -t 36000s -W <TCP WINDOW> -p <PORT> -H pkvsi2-ext -o <TELESCOPEID>
| Telescope | TCP Window (kB) | Port | ID |
|---|---|---|---|
| Parkes | 5 | 52100 | Pa |
| Mopra | 512 | 52101 | Mp |
| ATCA | 512 | 52102 | At |
E.g.
> vsib_record -t 36000s -W 512 -p 52102 -H pkvsi2-ext -o At
If Huygens cable is plugged in and you want the second DAS (eg ATCA), need to add -m 2 -c ox to get both bytes but drop one
If you need to drop the rate down to 128 Mbps add the option -c ooxx to get Rcp or -c xxoo for Lcp. If this is the case, the second DAS cannot be used (so the ATCA schedule must be changed to have 64 MHz into DAS1)
Running the correlator
On pkvsi2, go to /import/bd1/evlbi/tests/vt11c3/. Edit the .input file to have the correct start time (in the first table), and start the correlator with:
mpirun -p4pg p4pg.pkvsigateway /home/vlbi/evlbi/correlator/mpifxcorr/src/mpifxcorr /import/bd1/evlbi/tests/vt11c3/<input file name>
Wait for the startup messages to scroll through and stop - near the end there should be some saying “waiting for connection”. Once the correlator is waiting you can start the vsib_record processes at the observatories. The start time in the correlator input file should be after the time you get all these going.
If you want to add an extra antenna (eg hobart) to the array, you'll need to add an extra line to p4pg.pkvsigateway. Dupplicate the second line. For this instance you'll obviously also need a different correlator input file. Similarly, if for some reason we want to drop an antenna, remove the second line from p4pg.pkvsigateway.
