2009 April 15 

Present: Charles, Mark, Des, Mike, Aard, Dominik
   
   
   Aard- software corr optimization
   Mark- clusterized corr installation
   Des - web services (with D)
   Mike- GPU and other 
   
   1). Introduction [Mark]
           - current status
           - new version of software correlator deployed
           
   2). Work progress [Dominik]
           - see slides attached
           
   3). Discussion about usage of gridFTPServers
           - In order to use grid FTP server a certificate is required. There is  
             a problem with generation of a certificate for a software module.  
             It has to be associated with a person. Keeping the above in mind  
             we have decided that:
                   - the usage of file transfer protocol will be configurable,  
                     so it is possible to switch from one protocol to another
                   - we will use SCP whenever possible
                   
           
   4). Action Items 
           a). Testebed preparation
                   - correlator deployed on reef cluster at PSNC
                   - agreed to deploy separate software correlator
                           - at Jive, contact Mike about it
                           - at Psnc, check the availability of another cluster in 
                             PSNC where software correlator could be deployed. In  
                             case something is wrong with cluster at Jive. [Dominik]
                           - adding new software correlator requires installation  
                             and configuration of Correlation Node Module
                           
                   - translation nodes
                           - define a list of translation nodes which will be available  
                             (name, description, service endpoint and gridFtp address  
                             is required) [Des and Dominik]
                                   - now there is one at Jive, Huygens
                                   - the second one is being installed in Torun
           b). We agreed to have 4 virtual radio telescopes for a demo system
                   - A VEX file should be prepared for the system demo (for 4  
                     radio telescopes)
                   
           c). Check a policy about file transfer protocols at PSNC [Dominik]
           
           d). Implementation of missing software modules [Des and Dominik]
           
           e). Add possibility of returning feedback by software modules [Des and Dominik]  
           
           f). Monitoring
                   - required and useful
                   - agreed to implement a simple monitoring in WFM        [Dominik]
                   - advanced monitoring system will be created in the EXPReS continuation
                           - this would probably require changing the correlator code.  
                             Investigate the status info in software correlator - how it  
                             is done, how this information can be accessed by other  
                             modules [Aard]
