Hi there;Can someone point me to the minimum specs for a compute node in an HPC cluster. Does the node have to have a certain processor; A certain amount of ram? Do all the compute nodes have to be the same specs?I can find specs for the Head node but not the computer nodes. I realize that the more powerfull the compute nodes then the more powerful the cluster will be.Can compute nodes be added over time? Say add 10 nodes initially then add a node or two here and there as they become available.Every year the school I work for discards several 5 year old computers. Most of which go to charity or other schools. But I'm thinking of using some of them to build a cluster. Most of them are old Celerons with 512 MB of ram.Thanks for any and all commentsWD

Hello, According to the description, the issue seems to be related to Windows HPC server. As we mainly focus on the general question about Windows Server system, for better and accurate answer to that question, it is recommend you to get further support in one of the Windows HPC forums For your convenience, I have list the related link as followed.
