Hi all, I'm developing an application which need to use tools and other applications that excel in a distributed environment: - HPX ( https://github.com/STEllAR-GROUP/hpx ) , - Kafka ( http://kafka.apache.org/ ) - a blockchain tool. This is why I'm eager to learn how to deploy a beowulf cluster.
I've read some info here: - https://en.wikibooks.org/wiki/Building_a_Beowulf_Cluster - https://www.linux.com/blog/building-beowulf-cluster-just-13-steps - https://www-users.cs.york.ac.uk/~mjf/pi_cluster/src/Building_a_simple_Beowulf_cluster.html And I have 2 starting questions in order to clarify how I should proceed for a correct cluster building: 1) My starting point is a PC, I'm working with at the moment, with this features: - Corsair Simm Memoria RAM, DDR3, PC1600, 32GB, CL10 Ven k - Intel Ci7 Box Processore CPU 1150 i7-4790K, 4.00 GHz - Samsung MZ-76E500B Unità SSD Interna 860 EVO, 500 GB, 2.5" SATA III, Nero/Grigio - MB ASUS H97-PLUS - lettore DVD-RW I'm using as OS Ubuntu 18.04.01 Server Edition. On one side I read that it should be better to put in the same cluster the same type of HW : PCs of the same type, but on the other side also hetherogeneous HW (server or PCs) can also be deployed. So....which HW should I take in consideration for the second node, if the features of the very first "node" are the ones above? 2) I read that some software (Rocks, OSCAR) would make the cluster configuration easier and smoother. But I also read that using the same OS, with the right same version, for all nodes, in my case Ubuntu 18.04.01 Server Edition, could be a safe starter. So... is it strictly necessary to use Rocks or OSCAR to correctly configure the nodes network? Looking forward to your kind hints and suggestions. Marco
