Hi Christoph, You can get the ND header files (included in the NetworkDirect DDK zip file) here: http://www.microsoft.com/en-us/download/details.aspx?id=36043
There is no dependency on the HPC Pack - you just need drivers that support ND (ideally NDv2, which the Mellanox 4.40 release does). Using ND should give you the greatest hardware independence too, though by design ND exposes the lowest common denominator functionality of iWARP and InfiniBand, so some functionality is not available (e.g. RDMA atomics). Don’t hesitate to ask if you have questions. -Fab From: [email protected] [mailto:[email protected]] On Behalf Of Christoph Müller Sent: Thursday, August 15, 2013 6:04 AM To: Tzachi Dar; [email protected] Subject: Re: [ofw] Use of I/O completion port with Winverbs Thank you. I was not aware that the SDK including NDv2 is distributed with Mellanox’ drivers. In this case, I will give it a try.

I don’t think that you need to install the hpc pack for it. You simply need to run ndinstall and then you can start running nd programs. Thanks Tzachi From: Christoph Müller [mailto:[email protected]] Sent: Thursday, August 15, 2013 3:21 PM To: Tzachi Dar; [email protected]<mailto:[email protected]> Subject: AW: Use of I/O completion port with Winverbs Actually, I am in the process of deciding which API to use (although I have existing librdma code). NetworkDirect indeed looks promising, but as I understand, I need HPC Pack 2012 for that which I cannot install on our cluster in the short term.

If so, there are overlapped objects there that you should be able to connect to the completion ports.

I can see that the implementation inherits a handle from CWVBase, but I do not see how I could use this information for creating an IOCP and, of course, I do not know whether it would work. Furthermore, I would prefer continuing to use the RDMA library, but I see absolutely no way to create an IOCP here. So me questions are: Is it possible to use IOCPs with winverbs? Is it possible to use IOCPs with the RDMA library? Is there sample code for either of it?
