25Meg = 25 x 1024 x 1024 x 8 bits = 209715200 bits= minimum transfer time of about 20.97 seconds Now that doesn't include all the packet headers, but we are showing a healthy 66% or therabouts with a 30 second transmission. But was that two machines linked with nothing else on? What

Thinking of building a Beowulf are we?g OK your 100 machines are likely to talk to each other at 100, but only at 10 to the 10s. If all your equipment were 100, then it would be indicative of a problem to see 100s running at 10. 3Com are usually solid cards. My main problem with them has been

Hi Folks, When I first fired up the machine, Linux detected the Ethernet card and used it fine. The card was sold to me as a 10/100BT, but Linux is only using it as a 10. Is there some setting I should fiddle with, or was I misled? Thanks in advance for any info! Sean
