I ran "top" in session #1 and 
"./x264 --quiet --qp 20 --partitions b8x8,i4x4 --ref 5 --direct auto --b-pyramid --weightb --mixed-refs --no-fast-pskip --me umh --subme 7 --analyse b8x8,i4x4 --threads 4 -o eledream.264 eledream_640x360_128.y4m" in session #2

Hi,
Can you give the following information to resolve your issue?
1) How many cores per CPU in your machine?
2) How many CPUs in your machine?
3) How do you know that only one processor is allocated to x264? 

Best,
Kishore

Hi
>I ran some PARSEC benchmarks on an Opteron processor to see if increasing the number of threads can allocate more processors. For example, I ran x264 with one thread and saw that only one cpu is allocated. Next when I ncreased the number of threads to 4, I saw again that only one cpu is allocated.
