Re: Linux390 LPAR - CPU info
What does the value tell you based on your current
program?
Part of the problem will be that the value will change depending upon
what else might be running on the mainframe

Re: Linux390 LPAR - CPU info
What type of application are you making that cares so much about CPU speed?
MIPS. Meaningless Indicator of Processor Speed. There are architectureal
differences between z/series and intel that add
Found one interesting number from DB2
on Linux on mainframe.
The command db2 get dbm cfg
is displaying some information about CPU speed. I don't know how valid
it is.
CPU speed (millisec/instruction)
(CPUSPEED) = 1.133626e-06
If i try converting this value to MIPS,
it's coming around 880

Yeah. But still i want to show some value which represents the CPU
capacity configuration of the machine.
For what purpose? Help us out here -- we're having a really hard time
understanding why you care about this number, other than having
something cool to print out. Do you adjust algorthms
printing the number out since it's generated so many questions over the
years.

Is there some reason what that number is important to you? I've been doing
working with Linux/390 for 4 years now, and I've never much cared.
Depending on what processor type (G5, G6, z990, etc.), it is somewhere in
the range of 200MHz to 700Mhz, if all you're interested in is clock speed.
