How to correctly set up IMPI?
I guess this one is a bit more tricky to trouble shoot, but here's what I have:
* IMPI network was set up during installation;
* cabling done;
* anything to check in BIOS?
* following QluMan guide "3.7. IPMI settings" I set "Initialize IPMI: true" in "Generic Property Set" assigned to nodes;
* nodes "Hardware Property Set" has "IPMI Adapter: true";
Rebooted everything, started "console-login", but see only headnode.
What did I miss?
I need to increase Open file limit on the nodes. Should I use customized "limits.conf" and follow admin guide "4.2.5. Adding directories, files, links"?
* soft nproc 10024
* hard nproc 10024
* soft nofile 50024
* hard nofile 50024
* soft memlock 255707144
* hard memlock 255707144
my/limits.conf /etc/security root:root 644
Is that a good way?
I would like to limit access to the cluster via hosts.allow and hosts.deny. What is the best way to do it?
I could create a script in /etc/qlustar/common/rc.boot/
that looks like this:
echo 'sshd: ALL' >> /etc/hosts.deny
echo 'sshd: localhost' >> /etc/hosts.allow
echo 'sshd: xxx.xxx.xxx.xxx' >> /etc/hosts.allow
Is that ok?
here's a question that cropped up during my search for HW Threads (see
other message), but is actually unrelated: how do I edit HW property
sets? If I use the pop-up menu to, say, change the number of cores
from 10 to 20, the change reverts upon closing the property sets
window. The context menu of the property has "Delete Property", but
that has no effect; the context menu of the property set has "Edit
Property Set", but that pertains only to the set's name and
description, not the contained properties.
Thanks a lot,
does Qlustar handle hardware threads? SLURM has the triple
sockets/cores/threads, so I'd expect to be able to configure this
somewhere. However, I couldn't find anything in the docs (or in
