SIMION 8.0 Issues/Bugs/Enhancements

Filter issues by query:
Issue I163 2006-02-08 [pa,resolved]
  Title: More than 50 million points in a PA.

  SIMION 7.0 is limited to 50 million points per PA.  For a 3D PA this
  is roughly a cube side 368, and uses 500MB RAM. (Many users now have
  2 to 4GB ram, so this could be usefully raised.)

  As of 2006-02-08 in 8.0, this limit is increased to 400 million
  points in 8.0beta8 (~4GB), but in practice it is close to ~200
  million (~2GB) in WinXP.  Allocating arrays larger that about
  1.3 GB may require using the "--reserved-memory" command-line
  parameter (see Issue I363).

  2 or 3GB is a fundamental limit though, and going beyond it would
  require that Issue I175 be addressed.

  Reported by various users including dennisc.
