[ADMB Users] survey of memory settings in ADMB

[John Sibert]

Hi Ian,
Not wanting  to think about it too much, I go big.
Here is what I use in one model:
>   #ifdef __x86_64
>     // 64 bit configuration
>     #ifdef USE_ADMPI
>       arrmblsize= 10000000;
>       gradient_structure::set_CMPDIF_BUFFER_SIZE(  150000000L);
>       gradient_structure::set_GRADSTACK_BUFFER_SIZE(12550000L);
>       gradient_structure::set_MAX_NVAR_OFFSET(1000);
>     #else
>       arrmblsize= 10000000;
>       gradient_structure::set_CMPDIF_BUFFER_SIZE( 1500000000L);
>       gradient_structure::set_GRADSTACK_BUFFER_SIZE(50000000L);
>       gradient_structure::set_MAX_NVAR_OFFSET(1000);
>     #endif
>   #else
>     // 32 bit configuration
>     arrmblsize=  1000000;
>     gradient_structure::set_CMPDIF_BUFFER_SIZE(  150000000L);
>     gradient_structure::set_GRADSTACK_BUFFER_SIZE( 5000000L);
>     gradient_structure::set_MAX_NVAR_OFFSET(1000);
>   #endif
