LISA: Hangs with 1GB weights file #138

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
LISA hangs or crashes with a 1GB weights file on the Mac. It does work in 
Windows. For details and test dataset, see emails with Colin Robertson on and 
around May 11, 2011. Use 15000 as the distance cut off for the gwt weights.

This was likely due to running out of memory since previously when openning a 
GWT file, a GWT object in memory was first created and then converted to a GAL 
object.  This would require over 2GB of memory, which is near the limit of what 
Win32 can handel.  In release 0.9.9.13.6 and later, GWT files are read directly 
to a GAL object which will half the memory requirements.
