Date Location Title Participants Outcome (Short report & Indico URL)
13/12/2011 Tehran, Iran 4th HPC and Grid Workshop 50 As an invited lecturer, SCL's Vladimir Slavnic visited Tehran, Iran from 13 to 19 December 2011, where he participated in the 4th Workshop on High Performance and Grid Computing, held at the Institute of Research in Fundamental Sciences (IPM). Through morning lectures and afternoon hands-on sessions, this workshop covered various topics and concepts of Grid and High Performance Computing.

Vladimir Slavnic lectured on e-Science and Grid computational infrastructures, introduced Grid projects (EGI-InSPIRE) and middlewares, as well as gLite specific topics such as security, virtual organizations concept, information system, workload and data management. Together with IPM colleagues, Vladimir Slavnic held a series of hands-on sessions where participants had an opportunity to submit jobs and use storage resources of Iranian Grid resource centers.

In addition to lectures and hands-on sessions, Vladimir also worked together with Iranian colleagues on establishing new Grid services and making them available to researchers.

Beside Grid computing, the workshop also covered various other topics, such as advanced Linux usage, distributed and shared memory programming techniques with MPI and OpenMP examples, testing and benchmarking, financial risk calculation (Map/Reduce programming metaphor), etc.

2.1. Progress Summary

  • Operation of BDII/WMS/LB/VOMS/PX/LFC/Pakiti services for NGI_AEGIS, ATLAS and CMS VOs.
  • Dealing in timely manner with all security issues broadcasted by the EGI-CSIRT team.
  • Significant increase of AEGIS VO members (more than 20% in this quarter). Current number of members is 111.
  • Update of CA RPMs: EGI Trust Anchor release 1.43.
  • Providing input in the timely manner for the "Virtual Team: Website Content" (response to the Virtual Team questionnaire and inputs to the EGI Wiki).
  • Operational support to NGI_BA and NGI_GE.
  • Providing support to IRAN-GRID site administrators.
  • Regular middleware updates on all NGI_AEGIS sites.
  • Attendance to Operations Management Board and Operations meetings.
  • Maintenance of CREAMCE, WMS, and LB staged rollout services.
  • Dealing with top-BDII memory issue ( and implementation of suggested mitigation methods in order to maintain high availability of NGI_AEGIS top-BDII instance.
  • Deployment of set of programs for molecular modeling and cheminformatics provided by OpenEye software at the AEGIS01-IPB-SCL Grid site.
  • Regular maintenance and update of SAM packages (SAM Update-15) of NGI_AEGIS Nagios box. This Nagios instance is responsible for NGI_AEGIS and NGI_GE.
  • Reporting ATP problem ( that causes problem with MPI test on Nagios box (
  • Mayor network upgrade at AEGIS09-FTN-KM grid site (establishment of optical link to Serbian NREN).
  • Installation of in-house developed gcertcheck tool that checks validity of hosts and user certificates at the AEGIS01-IPB-SCL grid site.
  • Deployment of EMI BDII_top at AEGIS01-IPB-SCL Grid site.
  • Maintaining an excellent NGI availability/reliability and ROD performance index metrics.
  • Contribution to EGI survey: Feedback about EGI Global Services.
  • Contribution to EGI survey: Assessment of the NGI International Task.
  • Maintenance of NGI_AEGIS Helpdesk.
  • Operation of AEGIS CA.

2.2. Main Achievements

  • Due to strong advertisement of AEGIS and EGI infrastructure to the user communities, in the last quarter we recorded a significant increase of AEGIS VO members (more than 20%). According to the AEGIS VOMS server total number of members is 111.
  • Mayor network upgrade at AEGIS09-FTN-KM grid site (establishment of optical link to Serbian NREN).
