I have similar problem than the one posted a while ago in
Using cygwin/g77, in a PC with 1024 Mb of physical memory.
After compiling and running the following test program
the limit of 160 Mb cannot be surpassed.
implicit double precision (a-h,o-z)
c ny=200 works (160 Mb), > 200 doesnt (message error see beloww)
c dimension a1(nx,ny)
write(6,*) 'megabytes= ',nx*ny*8/1d6
write(6,*) 'extremes initialized'
error message after running
C:\cygwin\home\dchialvo\test.exe (1972): *** MapViewOfFileEx(0x71C, in_h
0x71C) failed, Win32 error 6
I follow each one of the recomendation described here:
setting the limit at 1024 Mb,etc, the registry shows that there
1024 allocated however the problem persist,
no more than 160 mb can be allocated.
Any suggestions will be appreciatted
