[gpfsug-discuss] Meltdown, Spectre, and impacts on GPFS

[Richard Booth]

Dear Kevin

The company I work for might be able to help get back the performance lost
from the fixes for Meltdown and Spectre.

I work for Ellexus, an I/O profiling company. Our tools could help identify
any inefficient I/O patterns in your applications to reduce the impact of
this. We can set up demos and a free trial if you're interested in seeing
what we do and how we can help.

Kind regards
Richard

Happy New Year everyone,

I?m sure that everyone is aware of Meltdown and Spectre by now ? we, like
many other institutions, will be patching for it at the earliest possible
opportunity.

Our understanding is that the most serious of the negative performance
impacts of these patches will be for things like I/O (disk / network) ?
given that, we are curious if IBM has any plans for a GPFS update that
could help mitigate those impacts?  Or is there simply nothing that can be
done?

If there is a GPFS update planned for this we?d be interested in knowing so
that we could coordinate the kernel and GPFS upgrades on our cluster.

Thanks?

Kevin

P.S.  The ?Happy New Year? wasn?t intended as sarcasm ? I hope it is a good
year for everyone despite how it?s starting out.  :-O
