I'm using CYGWIN_NT-5.1, under XP Pro.
I've set my heap_chunk_in_mb registry key to a very large value (10240 decimal,) because I'm doing some RAM-hungry numerical calculations.
I have enough space to do this (Control Panel->System reports 12 GB of virtual memory allocated.)
However, the max_memory program at <http://www.cygwin.com/ml/cygwin/2003-02/msg00234.html> still reports only 1.5 GB available. Sure enough, my program dies with an "out of memory" error at 1.25 GB (the 0.25 GB discrepancy is about right for the amount of RAM other processes are using.)
Anyone got any ideas what's happening, please?
cygwin doesn't emulate a 64-bit OS. Did you try setting up XP with /3GB to see whether that would give another 1 GB, or check the archives for any reports on such an attempt?
