Script - Find cpu - model / type / count / core / thread / speed - Solaris Sparc

           

           -  Purpose of this script - Find the CPU count, Model, Type, Physical Count, Core, Thread, Speed and vCPU mapping with Physical CPU
          -  Use the script in Solaris Sparc servers
          -  The output as below
                    CPU Model is : UltraSPARC-T2
                    CPU Type is : sparcv9
                    Total number of physical processors: 1
                    Number of virtual processors: 64
                    Total number of cores: 8
                    Number of cores per physical processor: 8
                    Number of hardware threads (strands or vCPUs) per core: 8
                    Processor speed: 1165 MHz (1.16 GHz)
