cpu core number
hi everyone
i have a Linux server (redhat 5.3) on HP DL580 G7 server. it has 4 cpu socket with cpu interl xeon(R) E7-4850 2GHz. when i want to see cpu cores by mpstat (cat /proc/cpuinfo too) it shows me 80cores!! but i think it must show only 40cores. what should i do? thanks inadvance
#mpstat -P ALL
Linux 2.6.18-128.el5 02/13/2013
