CorrPrepFaq This is a bare-bones guide to preparing an experiment for correlation on the CCC incarnation on juw32/juw31: * The machine name is ccsops (login as jops). * The experiment directories are: /ccs/expr/{EXP} [{EXP} = experiment name in capitals]

jaw2 This system serves as the boot server for the HP-RT systems and runs some processes that are necessary to configure the correlator. Information on how to reinstall this system from scratch can be found here. The ICT department knows the root password for this system.

EvnSession This page covers all you want to know about an EVN experiment or a session. If you are clock-searching an experiment and you do not know whether Westerbork observed as a phase array or used a single dish, just go to the EVN feedback pages! If you would like to process your VLBI data and want more information, you are at the right place!

Correlator operations These wiki pages should answer all your questions about the correlation process at JIVE in the broadest sense. The items range from simple recipes (How do I print VSN labels?), to full manuals (How do I make FITS files?). Look around

New jaw0 The replacement for jaw0 has been named `jaw2`. This machine will only be used for booting the HP-RT systems in the correlator and booting the Station Units. Nothing else should live on this machine anymore. There are actually two nearly identical machines that are both `jaw2`, one of them serving as a cold spare. Because both machines have the same IP address, they should never both be connected to the network at the same time. There is also a full Ignite-UX disaster-recovery bac…

PCInt design A solution that meets the requirements is the following: * Each correlator rack will be fitted with two DSP-boards (quad TexasInstruments C6x). These boards feature two PEM-slots (Processor Enhancement Module) and one PMC (PCI Mezzanine Card) slot. The two PEM slots will be equipped with a PEM-C40 module each. The PMC slot will be fitted with a SCSI controller.

PCInt requirement specification The Post Correlator Integrator (PCInt) enhances the capability of the EVN MkIV Correlator by providing an output path for data rates that exceed the maximum transfer rate of the LAN. To achieve this the PCInt receives outputs from the correlator and performs various re-ordering and DSP functions. In general these processes will result in a reduction in the volume of data to be passed to an output port and/or data storage device.
