<div dir="ltr"><div><div><div><div><div><div><div><div><div>Robert,<br></div> I have had a great deal of experience with Bright Cluster Manager and I am happy to share my thoughts.<br><br></div></div><br></div>My experience with Bright has been as a system integrator in the UK, where I deployed Bright for a government defence client,<br></div>for a university in London and on our in-house cluster for benchmarking and demos.<br></div>I have a good relationship with the Bright employees in the UK and in Europe.<br><br></div>Over the last year I have worked with a very big high tech company in the Netherlands, who use Bright to manage their clusters<br></div>which run a whole range of applications.<br><br></div><div>I would say that Bright is surprisingly easy to install - you should be going from bare metal to a functioning cluster within an hour.<br></div><div>The node discovery mecahnism is either to switch on each node in turn and confirm the name. <br></div><div>Or to note down which port in your Ethernet switch a node is connected to and Bright will do a MAC address lookup on that port.<br></div><div>Hint - do the Ethernet port mapping. Make a sensible choice of node to port numbering on each switch.<br></div><div>You of course have to identify the switches also to Bright.<br></div><div>But it is then a matter of switching all the nodes on at once, then go off for well deserved coffee. Happy days.<br><br></div><div>Bright can cope with most network topologies, including booting over Infiniband.<br></div><div>If you run into problems their support guys are pretty responsive and very clueful. If you get stuck they will schedule a Webex<br></div><div>and get you out of whatever hole you have dug for yourself. There is even a reverse ssh tunnel built in to their software,<br></div><div>so you can 'call home' and someone can log in to help diagnose your problem.<br><br></div><div>I back up what Chris Dagdidian says. You pays your money and you takes your choice.<br><br></div><div>Regarding the job scheduler, Brigh comes with pre-packaged and integrated Slurm, PBSpro, Gridengine and I am sure LSF.<br></div><div>So right out of the box you have a default job scheduler set up. All you have to do is choose which one at install time.<br></div><div>Bright rather like Slurm, as I do also. But I stress that it works perfectly well with PBSPro, as I have worked in that environment over the last year.<br></div><div>Should you wish to install your own version of Slurm/PBSPro etc. you can do that, again I know this works.<br><br></div><div>I also stress PBSPro - this is now on a dual support model, so it is open source if you dont need the formal support from Altair.<br><br></div><div>Please ask some more questions - I will tune in later.<br><br></div><div>Also it should be said that if you choose not to go with Bright a good open source alternative is OpenHPC.<br></div><div>But that is a different beast, and takes a lot more care and feeding.<br></div><div><br><br></div><div><br></div><div><br><br><br></div><div><br><br><br><br><br><br></div><div><br><br><br><br><br></div><div><br><br><br><br></div><div><br><br></div><div><br><br><br><br><br></div><div><br><br></div><div><br><div><div><br><br><br><br><br><br><br><br><div><br><br><br><br><div><div><br><br><br><br><br><br><br><div><div><br><br><br><br></div></div></div></div></div></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 2 May 2018 at 01:24, Christopher Samuel <span dir="ltr"><<a href="mailto:chris@csamuel.org" target="_blank">chris@csamuel.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 02/05/18 06:57, Robert Taylor wrote:<br>

It appears to do node management, monitoring, and provisioning, so we<br>
would still need a job scheduler like lsf, slurm,etc, as well. Is<br>
that correct?<br>

I've not used it, but I've heard from others that it can/does supply<br>
schedulers like Slurm, but (at least then) out of date versions.<br>
<br>
I've heard from people who like Bright and who don't, so YMMV. :-)<span class="HOEnZb"><font color="#888888"><br>
