With the following output

   RealMemory=64259 AllocMem=1024 FreeMem=38620 Sockets=32 Boards=1
   RealMemory=120705 AllocMem=1024 FreeMem=309 Sockets=32 Boards=1
   RealMemory=64259 AllocMem=1024 FreeMem=59334 Sockets=32 Boards=1
   RealMemory=64259 AllocMem=1024 FreeMem=282 Sockets=10 Boards=1

I want to know what happened to the FreeMem? For example, on compute-0-1,
there are 120GB of memory and the allocated size is 1024M. Why FreeMem is

Any idea?
