Operating Systems AIX Shared-SMT-4 vs Dedicated-SMT-4 on capped LPAR Post 302968204 by MichaelFelt on Saturday 5th of March 2016 05:23:02 AM
Old 03-05-2016
When running in Dedicated Processor mode - that parition may donate unused cycles to the shared pool. However, when using it's processors CPU1 will always be the exact same physical core, idem for the other three - whatever is assigned when it is activated is what they will be.

When running is Shared Mode only the number of virtual cores is defined. On a system with, e.g., 16 cores activated - while the PHYP will attempt to map virtual to the same physical core (aka Home node) - it is not a requirement - hence the physical core assigned may change (e.g., another LPAR is using it, so rather than wait for it to be free a different core is assigned)

p.s. When donating a core - if a dedicated (processor) partition wants it CPU the borrowing LPAR gets removed immediately by the PHYP.

Hope this explains the basics!

2. HP-UX

Anything like AIX's SMT?

I'm working on a system to monitor a wide-range of Unix platforms, and I'd like to know if HP-UX has anything similar to AIX's SMT (simultaneous multithreading)? If there a way to separate an HP-UX CPU into multiple logical partitions which can then act as multiple CPUs? Thanks in advance, Dave (0 Replies)

Shared memory for shared library

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability. Obviously, I'll have to worry about mutual exclusion. (0 Replies)

NAME
xfce4-power-manager - The Xfce 4 Power manager SYNOPSIS
xfce4-power-manager [options] DESCRIPTION
xfce4-power-manager manages the power sources on the computer and the devices that can be controlled to reduce their power consumption (such as LCD brightness level, monitor sleep, CPU frequency scaling). In addition, xfce4-power-manager provides a set of freedesktop-com- pliant DBus interfaces to inform other applications about current power level so that they can adjust their power consumption, and it pro- vides the inhibit interface which allows applications to prevent automatic sleep actions via the power manager; as an example, the operat- ing system's package manager should make use of this interface while it is performing update operations. You can run xfce4-power-manager from the command line without specifying any extra arguments. OPTIONS
--no-daemon Starts the power manager in non-daemon mode: useful for debugging. --restart Causes the running power manager to restart. --customize Shows the configuration dialog. --quit Causes any running instance of xfce4-power-manager to exit. BUGS
Please report any bugs to http://bugzilla.xfce.org/. Development discussion should be conducted on the goodies-dev@xfce.org mailing list. Usage related questions should be directed to the xfce@xfce.org mailing list. HOMEPAGE
