... The pinhole simulation program is a computationally and memory intensive task. ... A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. ...

... You are here: start €Ё difx €Ё difxmpi . ... difx:difxmpi . The DiFX software correlator uses MPI for organizing the spawning of processes on different computers and for transmitting data from one process to another. MPI is used only for communication between mpifxcorr processes. ... MPI assigns each process that it starts an integer identifier (called rank) that is used to refer back to that process. ... A vast majority of known DiFX installations use OpenMPI (available at www.openmpi.org ). ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... The ESO-MIDAS system is built along lines which should allow easy integration of complex analysis algorithms as well as allowing greater flexibility in interactive use and in the creation of user specific procedures from the basic building blocks. The first design proposal for ESO-MIDAS, made late 1980, used some ideas from the UK STARLINK project for the software interface definitions. ... It consists of the following three parts, the monitor, the applications, and the interfaces. ...

... We then updated to PVCam 2.7.4.2, but we still see corrupt images if we don't close and reopen the camera after every exposure sequence, and the camera sometimes fails to respond to a trigger pulse. ... Close and re-init the camera, as follows: ... pl_cam_close(0) pl_pvcam_uninit() pl_pvcam_init() . ... power off camera . ... Call pl_exp_start_cont (to start a continuous exposure sequence into a circular buffer) with a circular buffer that holds too many images and you will hang your computer. ...

... Software requirements . ... SAOImage DS9 is an astronomical imaging and data visualization application used by SAS . ds9 latest stable version 4.12 works fine with SAS 7.1.0 . ... We recommend the installation of HEASOFT version 6.0 (HEADAS) or later, since SAS 7.1.0 was built with that version (except for Mac OS X where version 5.3 was used). ... To work with this release of SAS on any Mac OS X version, the X Windows software or X11 (a.k.a X11R6) for Mac Os X must be installed . ...

TransNix is the software that will control the three different processors involved in the detector control and in the low-level data handling. ... the DSP 56001 processor, that sends to the detector chip the clock wave patterns; . ... the host computer, responsible of writing the raw data on disk, and communicating between the TransNix and the high level software (XNIR); in the laboratory versions, it will be based on an Intel processor, using Linux as operative system,. ...

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ... We've put Python (plus all relevant libra
