 +====== 1 Internal Meeting ======
  
 +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]
 +           
 +
