Number of Socket, Cores, and hardware therads are common question that we need to know about a system running an Oracle database, one that is being used as a Hadoop NameNode or a DataNode.
The /proc/cpuinfo gives us fair bit of that information, but the dmidecode gives us some more detail.
We see below that the dmidecode tells us that we have 2 sockets, and that there are 12 hardware threads that are running per socket. Also, we can see that each socket has 6 cores.
