I ran across some info stating that a current optimum page size for IA64-Linux is 16KB; any validity to this? Are there any major side effects of changing the page size? --------------------------- We are porting and beginning to benchmark a subset of high performance applications, are there any other recommendations for optimizing the Linux kernel, or is there a better tuned kernel available anywhere? Thanks. *************************************************************************** Donny Cooper | Direct Phone : (281) 465-1506 NEC Systems, Inc. | Houston Metro: (281) 296-0912 x 1506 High Performance Computing Center| Fax : (281) 465-1599 4200 Research Forest Dr, #400 | E-mail : dcooper@atcc.necsyl.com The Woodlands, TX 77381 | URL : http://www.necservers.com *************************************************************************** -----Original Message----- From: linux-ia64-admin@linuxia64.org [mailto:linux-ia64-admin@linuxia64.org]On Behalf Of Don Dugger Sent: Monday, April 16, 2001 3:16 PM To: Michael Madore Cc: linux-ia64@linuxia64.org Subject: Re: [Linux-ia64] Page size Mike- You are correct, page size is a compile time constant, you cannot change it at run time. The `getpagesize' GLIBC function returns the kernel's page size.
