I would be very interested in the current state of mainframe Linux. It would be nice to know where it is being used. In our own environment we use AIX rather than Linux (which seems like a waste).<br><br>-- <br><br>Warm regards,<br>

yes.<br>
<br>
I'd like to know what a mainframe is in todays terms<br>
running Linux, and what apps on linux take advantage.<br>
<br>
It seems like the x86 ( as the popular example )<br>
has the architecture of what used to be a mainframe.<br>
For example, virtual architecture, loose and tightly coupled<br>
cores, multicores, shared memory, modules in racks and<br>
bios or monitor or no (?), RISC vs complex, multiple racks<br>
and the communication system (Tokien Ring?<g>).<br>
<br>
and of course, how linux is used in the mainframe.<br>
<br>
Perhaps the context would be an x86 in a mainframe architecture?<br>
IOW, I don't know.<br>
A "CPU context" discussion comparing your mainframe CPU to x86<br>
might be interesting to those with only x86 experience.<br>
<br>
<br>
thx for offering,<br>

Hi Eric,<br>
<br>
I'd be interested. The points Walt raised would also be interesting to discuss if you are able to talk about them.<br>
<br>
Thanks,<br>
