Yes. 2. Yes. Look at programmer's guide section 16 Multi-process support. 3. You can use blacklist eal option. Regards, Vladimir 2014-03-28 13:25 GMT+04:00 Sujith Sankar (ssujith) >: Hi all, Could someone answer the following questions about the usage of multiple NI= C interfaces with DPDK? 1. If my server has two identical Intel NICs, could I use both with DPDK a= nd its applications? 2. If both the NIC cards could be used with DPDK, could I use them with se= parate instances of applications? E.g., NIC1 used by App1 and NIC2 used by= App2. 3. If answer to qn no 2 is yes, does the driver take care to avoid reiniti= alising NIC1 when App2 tries to initialise NIC2? From what I=92ve seen, DP= DK calls the driver init for all the matching devices (vendor id and device= id). Thanks, -Sujith
