[ADMB Users] survey of memory settings in ADMB

[Arni Magnusson]

More examples I have come across:

ADCAM (stock assmt model by Bjornsson)

TOP_OF_MAIN_SECTION
   gradient_structure::set_CMPDIF_BUFFER_SIZE(10000000);
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(1000000);
   gradient_structure::set_MAX_NVAR_OFFSET(1500);
   gradient_structure::set_NUM_DEPENDENT_VARIABLES(1500);
   arrmblsize = 50000000;


AMAK (stock assmt model by Ianelli)

TOP_OF_MAIN_SECTION
   gradient_structure::set_MAX_NVAR_OFFSET(1000);
   gradient_structure::set_NUM_DEPENDENT_VARIABLES(1000);
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(1000000);
   gradient_structure::set_CMPDIF_BUFFER_SIZE(10000000);
   arrmblsize=500000000;


Stock Synthesis (stock assmt model by Methot)

TOP_OF_MAIN_SECTION
   arrmblsize = 50000000;
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(20000000000);
   gradient_structure::set_CMPDIF_BUFFER_SIZE(170000000);
   gradient_structure::set_MAX_NVAR_OFFSET(5000);
   gradient_structure::set_NUM_DEPENDENT_VARIABLES(10000);


Pacific Ocean Perch (stock assmt by Stewart)

TOP_OF_MAIN_SECTION
   gradient_structure::set_MAX_NVAR_OFFSET(1000);
   gradient_structure::set_NUM_DEPENDENT_VARIABLES(800);
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(100000);
   gradient_structure::set_CMPDIF_BUFFER_SIZE(1000000);
   arrmblsize=900000;


Red Snapper (stock assmt by Prager)

TOP_OF_MAIN_SECTION
   arrmblsize=20000000;
   gradient_structure::set_MAX_NVAR_OFFSET(1600);
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(2000000);
   gradient_structure::set_CMPDIF_BUFFER_SIZE(2000000);
   gradient_structure::set_NUM_DEPENDENT_VARIABLES(500);


S-Atlantic Vermillion Snapper (stock assmt by Williams)

TOP_OF_MAIN_SECTION
   arrmblsize=2000000;
   gradient_structure::set_MAX_NVAR_OFFSET(300);
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(20000000);
   gradient_structure::set_CMPDIF_BUFFER_SIZE(100000000);
   gradient_structure::set_NUM_DEPENDENT_VARIABLES(300);


Walleye (stock assmt by Bence)

TOP_OF_MAIN_SECTION
   gradient_structure::set_GRADSTACK_BUFFER_SIZE(200000);
   gradient_structure::set_CMPDIF_BUFFER_SIZE(1000000);
   gradient_structure::set_MAX_NVAR_OFFSET(400);


Many of these settings might be arbitrary and even unnecessary, but may 
still give us some ideas for new defaults.
