Re: SMT8

I also read this:
http://www.ibm.com/developerworks/ibmi/library/i-ibmi-7_2-and-ibm-power8/
And on the lpar attributes on the HMC I see:
Processor Compatibility Mode
Compatibility mode: POWER8
Workload management
Partition workload group: (None)
Workload group: (None)

All 14 lpars of IBM i, (7.1 and 7.2) have system value QPRCMLTTSK set to
'2=System-controlled'.

I found this little snippet
<snip>
Simultaneous multithreading dispatch control
IBM i 7.2 adds a job attribute named Processor Resources Priority
(PRCRSCPTY) to
influence how threads for the job are dispatched. The PRCRSCPTY attribute
can request that
the system isolate threads for the job on processors that are running
fewer threads
concurrently, or that the system run threads for the job on processors
that are running as
many concurrent threads as possible.

5250 interactive jobs have
Allow multiple threads . . . . . . . . . . . . . : *NO
Specifies if the job can run with multiple user threads. This
attribute does not prevent the operating system from creating
threads in the job.

Processor resources priority . . . . . . . . . . : *SYSCTL
The processor resources priority associated with this job. If your
system has simultaneous multithreading (SMT) enabled, the processor
resources priority is used by the operating system to determine the
relative importance of the job when it is dispatched compared to
other jobs that are dispatched. The possible values are:

*SYSCTL The system determines the processor resources priority
for the job and its threads.

My Domino jobs seem to have:
Allow multiple threads . . . . . . . . . . . . . : *YES
Processor resources priority . . . . . . . . . . : *SYSCTL
