The sparcv9 processor operates at 1165 MHz, and has a sparcv9 floating point processor. Status of virtual processor 2 as of: 08/12/2009 12:01:00 on-line since 08/08/2009 06:03:05. The sparcv9 processor operates at 1165 MHz, and has a sparcv9 floating point processor. ......... Finding cores To find total number of cores across all the CPUs : # kstat cpu_info|grep core_id|sort -u|wc -l 16 Now to find number of core per CPU simply do the math : total number of cores / total number of physical CPUs Another way of gathering CPU related info is using the prtdiag command : # prtdiag -v | more System Configuration: Oracle Corporation sun4v SPARC T2+ Memory size: 65536 Megabytes ================================ Virtual CPUs ================================ CPU ID Frequency Implementation Status ------ --------- ---------------------- ------- 0 1400 MHz SPARC-T2+ on-line 1 1400 MHz SPARC-T2+ on-line 2 1400 MHz SPARC-T2+ on-line 3 1400 MHz SPARC-T2+ on-line 4 1400 MHz SPARC-T2+ on-line 5 1400 MHz SPARC-T2+ on-line 6 1400 MHz SPARC-T2+ on-line 7 1400 MHz SPARC-T2+ on-line 8 1400 MHz SPARC-T2+ on-line 9 1400 MHz SPARC-T2+ on-line 10 1400 MHz SPARC-T2+ on-line 11 1400 MHz SPARC-T2+ on-line 12 1400 MHz SPARC-T2+ on-line 13 1400 MHz SPARC-T2+ on-line 14 1400 MHz SPARC-T2+ on-line 15 1400 MHz SPARC-T2+ on-line .... Gathering Memory information Getting memory information is trivial. use the prtconf command and grem for Memory : # prtconf | grep Memory Memory size: 65536 Megabytes We can also use the prtdiag command to find the memory in the system : # prtdiag -v | grep Memory Memory size: 65536 Megabytes Finding CPU information on T-series hardware with LDOMs If you have LDOMs installed on the T-series hardware tyhat you have, above commands may not give you the correct values. Use the “ldm list-devices -a” command to list core, virtual CPUs (VCPUs) and resource assignments. # ldm list-devices -a CORE ID %FREE CPUSET 0 12 (0, 1, 2, 3, 4, 5, 6, 7) 1 0 (8, 9, 10, 11, 12, 13, 14, 15) 2 0 (16, 17, 18, 19, 20, 21, 22, 23) 3 0 (24, 25, 26, 27, 28, 29, 30, 31) 4 0 (32, 33, 34, 35, 36, 37, 38, 39) 5 0 (40, 41, 42, 43, 44, 45, 46, 47) 6 0 (48, 49, 50, 51, 52, 53, 54, 55) 7 0 (56, 57, 58, 59, 60, 61, 62, 63) 8 0 (64, 65, 66, 67, 68, 69, 70, 71) 9 0 (72, 73, 74, 75, 76, 77, 78, 79) 10 0 (80, 81, 82, 83, 84, 85, 86, 87) 11 0 (88, 89, 90, 91, 92, 93, 94, 95) 12 0 (96, 97, 98, 99, 100, 101, 102, 103) 13 0 (104, 105, 106, 107, 108, 109, 110, 111) 14 0 (112, 113, 114, 115, 116, 117, 118, 119) 15 0 (120, 121, 122, 123, 124, 125, 126, 127) 16 0 (128, 129, 130, 131, 132, 133, 134, 135) ...........................
