I’ve been trying to code using IBverbs lately and I have to confess that it was almost a total failure. I am used to program using Sockets, Myricom MX or Quadrics QsNet interfaces, they are very easy to use (like 20 lines for init and 10 lines per communication). IBverbs seem to require like 200 lines of init and 100 per communications, with lots of structure and functions I have no clue about. I don’t understand why this API needs to be so complex while it does not bring any additional feature compared to MX or Quadrics (the RDMA vs Message Passing war does not matter here), I never missed anything when using the other API for HPC programming. So, I’ll be at your talk and I hope you’ll explain everything I need to become an IBverbs master.
