CPU > 100% with serial version VASP

[xujc1983]

hello, everyone,
I have compiled serial version VASP 5.3.5 with ifort-12.1.5, icc-12.1.5 and openmpi-1.6.5 without any error.
But, when I run VASP (serial version) in a node (AMD, 4 core), the CPU utility is greater than 100%, even 1800%.

Could someone help me to find where the error is.
Thanks for advanced!
