RE: Running jobs on a separate core



fixed

I agree....we are totally guilty of that. Unfortunately our project timelines are so tight and many projects are back to back that we do not have the time to check it (yes, it's a sad excuse, but it's unfortunate reality).

7.1 has been GA for over 4 years now. Since 4/23/2010. Now, by dragging your feet in going to 7.1, you have taken going to Power 8 off the table.
Having personally worked on Power 8 equipment and the awesome, FREAKING AWESOME, performance benefits I am seeing on it, I really think any second you delay in getting to 7.1 (or beyond) is another bullet through your foot.

What hardware are you running that you've not gone to 7.1?

Thanks, Rob.

In reviewing various documents a lot of them point to creating a new
subsystem and pushing the QZDASOINIT jobs onto it. I guess it's something
we'll have to investigate once the new box arrives.

We would have purchased one of the new i8 boxes coming out next month, but
our applications are unproven on 7.1 and I wasn't going to risk having a
primary box with untested apps on it.

Now there's an oxymoron: "new 400".

I don't believe there is a way to dedicate out processors like you can
memory. With memory, you can bust it up into subsystems and whatnot. This
has been around since, well, back on 400's.
About the only way to dedicate processors is to create separate
partitions.

All,

In the next month or so our new 400 will be delivered to us. The new box
will have two cores because right now our single core machine is being
crushed by the QZDASOINIT jobs (they occupy anywhere from 75% - 90% of the

CPU utilization at any given time).

Yes, we are investigating the reasons why these jobs are occupying so
much, but I wanted to know if there's a way I can dedicate a core to a
specific job or subsystem? I would like to move the web jobs off to their

own core so the other core can focus on taking care of the other tasks.

Any advice or recommendations would be appreciated.


Thankee-sai!
