Hi all, I have, with my group, a small cluster of about 16 nodes (each one with single socket Xeon 3085 or 3110; And I face problem of poor scalability. Its network is quite ordinary GiGE (perhaps DLink DGS-1024D 24-Port 10/100/1000), store and forward switch, of price about $250 only. ftp://ftp10.dlink.com/pdfs/products/DGS-1024D/DGS-1024D_ds.pdf
How should I work on that for better scalability? What could be better affordable options of fast switches? (Myrinet, Infiniband are quite costly). When buying a switch what should we see in it? What latency? Thank you very much.
