top command doesn't display all processors running

Dear List, I am writting OpenMP parallel programs which use all the processors of my Quad Opteron baby! Now, suppose that all the 4 processors are running the same application. Typing #top I would expect to see 4 processes with 99.9% CPU usage. Instead of that I see only one! That is in my SuSE 9.2 AMD64. The same thing in SuSE 9.0 with icc compiler and OpenMP displays in top all the OMP_NUM_THREADS exported in bash by #export OMP_NUM_THREADS=4 even in a uni-processor pentium4. What is wrong with top in SuSE 9.2 and how can I fix it? Thanks in advance! Simeon! __________________________________ Do you Yahoo!? Yahoo!
