That's interesting.
I run Ferret on 2 Macs (G5 desktop with 5.5Gb physical memory and G4
powerbook with 1.25Gb), and routinely allocate 500MW of memory to
Ferret on both machines. (Despite the fact that the powerbook has
much less actual memory than that!). Some experimentation shows that
I can SET MEMORY/SI=[556 on the powerbook and 586 on the G5].
Anything more than that gives me the same error you describe. The
fact that the memory limits on both machines are the same gives me
the impression that this limit is not based on the physical memory
but on some other factor.
By the way, testing shows that the G5 is about 3-4 times faster than
the G4 laptop for Ferret operations.

Dear Ferreters,
I am using Ferret v5.70 on Mac OS X 10.3.
Although 4.5 GB physical memory is installed in my Mac,
I have a trouble about memory when I tried to allocate much memory
(ex. 500 Mega word = 2GB) as following.
NOAA/PMEL TMAP
FERRET v5.70 (alpha)
Mac OS X 10.3.4 - 10/08/04

yes? set memory/size=500
Cached data cleared from memory
*** malloc: vm_allocate(size=2000003072) failed (error code=3)
*** malloc[2950]: error: Can't allocate region
Unable to allocate 500.000000 Mwords of memory.
Restoring previous memory of 6.400000 Mwords.
yes?
Also, in the same Mac,
Ferret can allocate 400 Mega word memory.
Is there any advises or comments?
Thank you,
