<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">with your patience, the cmpost.c example and the OFED 1.1-rc4 on all machines I finally got a gen2 connection under SLES10 even with a 32-Bit executable on a x86_64 machine. Cool!</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Now the last part on my journey is standing out.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">It’s a gen2 client connecting to a gen1 IBGD server.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">I have to do this since my gen1 server is running a 2.4 Montavista RT Linux on a PowerPC that I can’t upgrade to gen2.</FONT></SPAN><SPAN LANG="de"></SPAN><SPAN LANG="de"></SPAN><SPAN LANG="en-gb"> <FONT FACE="Wingdings" SIZE=2>L</FONT></SPAN><SPAN LANG="en-gb"></SPAN><SPAN LANG="en-gb"></SPAN><SPAN LANG="en-gb"></SPAN><SPAN LANG="de"></SPAN><SPAN LANG="de"></SPAN><SPAN LANG="en-gb"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">BTW.: Our application is a high speed film image transfer in the film postproduction industry leveraging the benefits of the high speed IB RDMA transport. </FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">While I have gen1 to gen1 and gen2 to gen2 running the only thing that is missing is the gen2 connecting to gen1.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Just tried this with my test-executables but I did not get anything to the gen1 server. The gen1 userspace application does not even receive the IB_CM_REQ.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">So since your cmpost example did help me a lot on gen2 the question is:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Do you have a cmpost for gen1 IBGD I can use to connect from gen2 to gen1?</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Or is there any other trick to play here?</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-gb"><FONT SIZE=2 FACE="Arial">Thanks in advance for your assistance</FONT></SPAN></P>
