Ciao a tutti.
Nel mio notebook (Xp Pro, 2 Gb Ram) il file boot.ini č il seguente:
[boot loader]
timeout=0
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
Utilizzando un software di fluidodinamica (www.comsol.com) ho problemi di "mancanza" di memoria quando esegue simulazioni molto "spinte".
Il produttore del software mi ha consigliato di modificare il file boot dicendo:
------------------------------------------------------------------------
In Windows XP, you only have 2 GB of virtual address space available initially for a user process. This memory space is also sometimes fragmented by shared libraries. On Linux, UNIX, and Mac, you typically get between 3-4 GB of virtual address space available for your process. This address space is usually not fragmented. Windows XP Professional x64 edition does not suffer any notable problems from memory fragmentation since the available address space is extremely large. COMSOL Multiphysics supports the option in Windows XP professional and Windows 2003 Server to have 3 GB of virtual address space available user processes. This reduces the available address space for the operating system to 1 GB. To access it you must boot the system using an additional boot parameter. The following example shows how to enable application memory tuning by adding the /3GB parameter in the boot.ini file:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="????" /3GB
The "????" above can be the name of your operating system for example "Microsoft Windows XP Professional". Please note that the file boot.ini is critical to booting your system.
------------------------------------------------------------------------
Ora vi chiedo se ritenete possibile modificarlo esattamente come dicono loro.
Io ho provato ad aggiungere "/3GB" dopo "/fastdetect" ma il sistema mi va in crash durante l'avvio.
Cosa consigliate ?
Grazie mille !!!
