I'm curious how to report to our users that the number of available CPU cores on a given node are *(CoresPerSocket * SocketsPerBoard * ThreadsPerCore) - CpuSpecCount*. In a basic example, if the node has 32 cores and CpuSpecCount=1, then there's actually 31 cores available. If a user runs `srun -n32 -N1 bash` he/she will be denied for resources. Then, If a user runs `sinfo -O cpus,nodes` shows there's 32 cores available and the user is confused. How can the user clearly identify that in the above case, the exact number of available CPU cores available are 31 and *not* 32? -- Thanks, Daniel Healy
