  <title>  May 9th: Vacancy at the ESS DMSC as scientific software developer</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.1</date>
  <description><![CDATA[

   The interim ESS DMSC (Data Management and Software Center for the
   European Spallation Source) located at the Niels Bohr Institute,
   University of Copenhagen is seeking a candidate for scientific software
   development within areas of data analysis and simulation. More
   specifically, the work is oriented toward integration of the McStas and
   Mantid software packages.

   The advert is available through this link.

   For further questions or enquiries, please contact Prof. Stig Skelboe,
   Niels Bohr Institute, University of Copenhagen, skelboe@nbi.dk,
   phone +45 35321449]]></description>

  <title>  July 26th, 2011: McStas 1.12c on Mac OS X Lion - new DMG added to download</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.10</date>
  <description><![CDATA[
  section.

   A new DMG for Mac OS X 10.7 Lion has been put together and can be found
   in the download section.

   Note that to enable multi-core / parallel simulations, you need to
   compile openmpi yourself before installing McStas, since it is not
   provided by Apple on Lion. Alternatively you can perhaps get it via
   MacPorts.

   The DMG should also work on Snow Leopard - but all software on the DMG
   must be reinstalled if McStas was previously installed.]]></description>

  <title>  July 24th, 2011: McStas 1.12c on Mac OS X Lion - hold your horses!</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.11</date>
  <description><![CDATA[

   The newly released Mac OS X 10.7 Lion includes a lot of nice upgrades
   from Apple - including some that break the tool-layer and mpi support
   for McStas:

   Symptom Cause
   mpi compile fails The system-provided mpi is not detected by the McStas
   configure script
   mcgui does not start mcgui requires perl::Tk, and the version we ship
   with McStas 1.12c explicitly requires perl 5.8, which has been removed
   from Lion
   mcplot does not plot For plotting, we rely on the SciKarl port of
   pgplot, perl::PDL and perl::PGPLOT. The SciKarl perl modules are built
   for perl 5.8 which has been removed from Lion

   In conclusion: If you want to keep a functional McStas install, please
   do not upgrade to Lion yet!]]></description>

  <title>  March 12th: Respin of McStas 1.12c dmg for OS X Lion</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.2</date>
  <description><![CDATA[

   As reported to mcstas-users@mcstas.org, the McStas 1.12c dmg for OS
   X Lion was unfortunately corrupt. A new version of the image has been
   uploaded. The filename is slightly different to be able to
   distinguish the image from older downloads you may have.]]></description>

  <description><![CDATA[       functional version has been uploaded to the share. Thanks to
       providing a fixed component.
     * The previously released updated dmg image for Mac OS X should
       really only be used on Lion, not Snow Leopard, that is use this
       image on Lion and this image on older releases.]]></description>

  <title>  Nov 9th, 2011: Installation with MPI on Linux/Ubuntu 11.10</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.5</date>
  <description><![CDATA[

   It has been reported that the mpich2 parallel processing library should
   be avoided under Ubuntu 11.10 ('mpd' clashes with an other executable).
   Please install instead openmpi with e.g.:
  # sudo apt-get install openmpi-bin libopenmpi-dev

   or from Synaptic/Ubuntu Software Center.
   In case Mcstas was installed before openmpi, you will need to
   re-configure it with e.g.:
  # cd /usr/local/lib/mcstas/tools/perl]]></description>

  <title>  Oct 31st, 2011: LEGO (c) neutron scattering instruments controlled with McStas</title>
  <link>http://www.mcstas.org</link>
  <date> McNews.9</date>
  <description><![CDATA[

   We have set-up LEGO models of a TAS and crystal TOF instrument,
   using the NXT technology. This is a robotic model (it moves) to be
   used for teaching/training and in exhibitions. When a McStas simulation
   is launched on the PC, the model positions itself with the
   corresponding geometry.
   The methodology to build and control the models is detailed at

           ILL/Computing for Science/Virtual instruments/LEGO

   were you will learn:
     * the LEGO parts required, and how to order them
     * the building of the LEGO models
     * the Ubuntu computer to be configured (using t2n and nbc)
     * the control programs to load in the NXT
     * the McStas components to use in order to communicate with the LEGO
       model.]]></description>
