[ADMB Users] memory allocation error

[Fowler, Mark]

Attempting to run a (monstrous) model on a new machine with the latest
ADMB, I get a memory allocation error right off the bat, no churning.
This model runs on an XP machine with 4 GB RAM, whereas the new Windows
7 machine has 32 GB (paging file is 16x that of the XP machine), so
available memory can't exactly be the problem. Is there a difference in
the latest ADMB that accounts for this? Does the move from a 32-bit to
64-bit machine confound something? I notice that the System-Performance
Options-Advanced has changed between OS's. Both allow Processor
scheduling and Virtual memory adjustments, but only XP has a separate
Memory usage (Programs vs System cache). On both machines I opt for
Programs, but don't know how the Windows 7 machine resolves the absent
Memory usage block. The no-longer-working program was a Borland compile
with the following memory settings:

 

  arrmblsize=90000000;

gradient_structure::set_GRADSTACK_BUFFER_SIZE(2500000);

gradient_structure::set_CMPDIF_BUFFER_SIZE(200000000);

gradient_structure::set_MAX_NVAR_OFFSET(2500);

 

I also compiled a mingw version on the new system with the latest ADMB
(problems reported in earlier email were due to incompatible Borland
include files - resolved), and get the same response, immediate memory
allocation error with no churning.

 

Anyone know why it no longer obtains the needed memory?
