Hello, I am using a Myricom 10G card with Snort and I am trying to run Snort in parallel using taskset.  I am able 
get tcpdump to correctly run in parallel but for some reason when I run Snort in parallel only the first 2 instances 
of snort do any processing (and only their share).  So for 8 instances of Snort only the first 2 instances do 
anything (regardless of what affinity I set to them) and they only process 1/8th of the total packets each.  I have 
verified that both programs are using the correct libpcap that came with the card.  Any ideas? 

That might be a question for Myricom's support personnel.  I'm not familiar with their cards.
