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.
There can be configurations in IBM Server wherein a
standalone partition is created on some supported IBM Server
Or
A VIOS - VIOC LPARs created.
Now in both cases they are lpars. But if I want to differentiate b/w a standalone LPAR vs an VIOC LPAR how can I do..?

Hello.
I am new to this forum and I would like to ask for advice about low level POSIX programming.
I have to implement a POSIX compliant C shared library.
A file will have some variables and the shared library will have some functions which need those variables.
There is one special... (5 Replies)
Calling upon all Solaris zone experts.
I have a Sun T3-1 that is running a few whole-root zones. I've set the 'capped-memory' setting on all the zones.
However, I have a problem on the one zone. Under load it uses more memory that has been allocated to it.

Hi all,
I have the following configuration
2 ds3524 storage disk systems located over 2 locations
2 P720 server located over 2 locations
DS3524 are connected to san switch.
Each vio server has 1 fc adapter attached to a san switch.
per p720 server 2 virtual io servers. Vio 1 has 1 lun... (2 Replies)
How does capped-memory work in zones?
I have 32G of memory and 10 zones.
I want about physical=4G and swap=4G in each zone.
Is this possible? I am going over the 32G. (1 Reply)
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)
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)
