I found your test matrix size is very small. (The matrix size N 1000 x 1000).
That make you got not so good results with PGI-ATLAS on Linux Based ATHLON.
It is not related to PGI compiler nor Athlon CPU or Network.
Will you increase your matrix size to N 3000 x 3000 or 5000 x 5000 if you have enough Local Memory(RAM) ?
Have a nice day !
