[ofw] Use of I/O completion port with Winverbs

[Christoph Müller]

ndinstall is part of the HPC pack distribution? My main problem with ND is to find out how to get it...

Best regards,
Christoph

Please note that the windows APIs are changing from time to time and ND is probably the one that will stay longer since it is supported by MS.

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

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.

Best regards,
Christoph

can you write your application with Network Direct?
If so, there are overlapped objects there that you should be able to connect to the completion ports.

Thanks

Hi all,

I was wondering whether it is possible to use CreateIoCompletionPort etc. with IWVConnectEndpoints. 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?

Thanks in advance,
Christoph
