Dear Chandra Users,
This is a long overdue announcement of PVM_XSTAR, a software tool
which manages parallel execution of XSTAR jobs on independent sets
of parameters.
XSTAR is a computer code for calculating the physical conditions
and emission spectra of photoionized gases (Kallman & Bautista 2001).
It may be used as either a standalone application or in the form of
analytic models--such as warmabs--within spectral modeling packages
like ISIS, XSPEC, or Sherpa.
With pvm_xstar one can perform large-scale XSTAR simulations,
consisting of thousands or more serial XSTAR jobs, in the time
it has previously taken to compute only a handful of such models.
The software and documentation are available online at
http://space.mit.edu/cxc/pvm_xstar/
and an arXiv reference to the ADASS 2008 paper is available at
http://arxiv.org/abs/0901.1582
Regards,
Mike Noble
