(2010), "XSTAR: application deployment in the global cyber-infrastructure", High-resolution X-ray spectroscopy: past, present, and future, Utrecht, The Netherlands, March 15-17, 2010.. Abstract: Within the context of the Virtual Atomic and Molecular Data Center (VAMDC) project [1, 2] and with NASA and EELA-2 [3] support, the popular X-ray spectral modeling code XSTAR [4] has been adopted as a case study in application deployment in the new cyber-infrastructure. Its current flat-file atomic database is being migrated to both relational (SQL) and hierarchical (XML) schemata in order to evaluate data maintenance and integration arrangements, and to promote data exchange by a wider user community. CPU-intensive parameter sweeps are parallelized considering both grid and cloud computing environments to enhance performance and usability. We present a new generation of this package to be included in the spectral modeling portfolio of the International Virtual Observatory Alliance.
