I have a question about using RPM's for the portability interface on
different CPU's.
According to /usr/lpp/mmfs/src/README
The generated RPM can ONLY be deployed to the machine with
identical architecture, distribution level, Linux kernel version
and GPFS version.
So does this mean that if I have a heterogeneous cluster with some
machines on Skylake and some on Sandy Bridge but all running on say
RHEL 7.8 and all using GPFS 5.0.5 I have to have different RPM's for the
two CPU's?
Or when it says "identical architecture" does it mean x86-64, ppc etc.
and not variations with the x86-64, ppc class? Assuming some minimum
level is met.
Obviously the actual Linux kernel being stock RedHat would be the same
on every machine regardless of whether it's Skylake or Sandy Bridge, or
even for that matter an AMD processor.
Consequently it seems strange that I would need different portability
interfaces. Would it help to generate the portability layer RPM's on a
Sandy Bridge machine and work no the presumption anything that runs on
Sandy Bridge will run on Skylake?
JAB.
