[ofw] Hello there

[David Barrientos]

Hi Tzachi,

Thanks a lot for the help.

Our needs are: program at user mode level, right now we are interested in XP/2003, and in the future maybe move to 2008. We really want to get the maximum of the card for low latency. We need to handle multicast traffic (UDP), as well as TCP traffic. I went through the Mellanox webpage, and couldn't find any place where you guys provide documentation/apis to download. Should I keep looking there or this mailing list is going to help me to get where I want?

Thanks again for the help.


Regards,

Hi David,

If you want to overcome tcp/ip limitations you have reached the correct place.

There are a few apis that can be used in order to do that. In order to get the best API that you need we need to understand the following information:


1)      Do you want to program using the user mode or kernel mode?

2)      What operating system are you interested? (xp, 2008, R2 )

3)      What do you want from your program? High BW? Low latency? Low cpu utilization?

4)      How important to you is it to really get the maximum from the card? (there are apis that are simpler, but get to somewhat worth performance)?

5)      Do you want to use multicast?

6)      What is the scale of your application?

There is also documentation for IBAL (if you download the Mellanox VPI package) and ND (in MSDN). Still we need more information about your needs to get to the right APIs.

Thanks
Tzachi

Hi,

My name is David and I'm a software engineer. Currently I'm interested in APIs that bypass the Windows (kernel) TCP/IP stack, and I've been told that OFED is the answer to my prayers. My company already bought Mellanox NIC (Ethernet), so now is time to change our software. I've been checking the openfabrics webpage, and wiki.openfabrics.org, although we can find some documentation, I don't know where to start. Is there anyone that can point me to the right direction? Like: Which API's for windows to use for Ethernet NICS? Is there documentation to that particular API? Can I find API's for c# and/or c++?? Any other information will be much appreciated.

Thanks a lot


Regards,

David Barrientos Velasco
