For Intel processors we've a lot of new instruction sets (AVX and AVX2 already exists, AVX512 is announced). Therefore an application has to check during run time which instruction sets are available. I've written for that purpopse some procedures, which are callable from C or C++.

Hi.
I need to migrate the whole unix environment from a Unix mp-ras 32 bit to a Linux Suse 64 bit.

2) can i just copy the users from unix to linux or do i have to create them by hand
3) are there any other concerns i should worry about?
thanx (1 Reply)

4. Solaris
Not really a Unix question as such :o, but what advantages or disadvantages are there between using 32bit or 64bit applications on a T5220 running Solaris 10? What about mixing them e.g. 64 bit app using 32 bit libraries or vice versa? (1 Reply)

Hi all,
I'm looking to cover a corner case for an upcoming test cycle. Is there a way to boot a RedHat Advanced Server 4 (update 3) installed on a Power PC machine to use a 32 bit kernel? This would be similar to what is done here -> https://www.unix.com/aix/26204-aix-platform.html

Where can I get a list that maps the each Linux version to corresponding 32/64 bits model?
e.g.
OS -> Model (ILP32, LP64, ...)
RHLE3 -> ?
RHLE4 -> ?
RHLE5 -> ?
...
It would be better if there is such a list that contains most of current UNIX OS versions.

GETGID(2) Linux Programmer's Manual GETGID(2)
NAME
getgid, getegid - get group identity
SYNOPSIS
#include <unistd.h>
#include <sys/types.h>
gid_t getgid(void);
gid_t getegid(void);
DESCRIPTION
getgid() returns the real group ID of the calling process.
getegid() returns the effective group ID of the calling process.
ERRORS
These functions are always successful.
CONFORMING TO
POSIX.1-2001, POSIX.1-2008, 4.3BSD.
NOTES
The original Linux getgid() and getegid() system calls supported only 16-bit group IDs. Subsequently, Linux 2.4 added getgid32() and gete-
gid32(), supporting 32-bit IDs. The glibc getgid() and getegid() wrapper functions transparently deal with the variations across kernel
versions.

getresgid(2), setgid(2), setregid(2), credentials(7)
