Each of the more than 200 scientific projects currently being investigated on the Centre's supercomputers is assigned an advisor from our ParaTeam who, typically, is an experienced scientist in the respective research area. The ParaTeam is an interdisciplinary group of staff members from the divisions Application Support, High-Performance Computing Systems, Computational Science, and Mathematics and Education. Team members spend an individual share of their manpower on high-level user support. Users requesting help with implementing, porting or optimizing their applications on our supercomputer systems are referred to their personal advisor who mostly has an own background in scientific computing, and who is backed by specialists in algorithms, parallel programming, programming languages, compilers, libraries, and tools.
Also the technical review of project proposals is performed in this team, the ParaTeam is led by the High-Level User Support.
There are three special task forces taking care of code scalability:
The cross-sectional team "Mathematical Methods and Algorithms" provides know-how in numerical kernels and assists users in using these algorithms: Mathematical Methods and Algorithms
The cross-sectional team "Performance Analysis" offers several tools to analyze parallel programs and supports in the usage of these tools : Performance Analysis
The cross-sectional team "Application Optimization" offers special support for users on program optimization: Application Optimization
The cross-sectional team "Visualization" gives support for the visualization of scientific data and for multimedia productions: Visualization
All teams are strongly collaborating with the simulation laboratories.
Technology support (JSC internal only)
JSC's technology support team supports JSC colleagues in all topics concerning IT technology. The team offers an "all-round carefree package" for desktop hardware, supports tasks concerning x86 servers and storage, carries out hardware installations, provides virtual systems on the VMware complex, operates a workstation group as a central Linux system for JSC colleagues and the IT systems of the three training rooms at JSC.
