RTS state Description In order to move to this state, one must call ibv_modify_qp() from RTR, or SQD states. If the other side (which didn't move to Error) won't send any message - it won't know that its remote QP moved to Error. It can be one of the enumerated values as qp_state path_mtu The path MTU (Maximum Transfer Unit) i.e. The actions taken by the RQ Logic are determined by the request type: — If it’ s a duplicate RDMA Read: – The RQ Logic re-executes the read from its local More about the author

Can you please write explicit the values that you set + the used mask in the ibv_modify_qp()? Only Work Requests in the receive queue will be processed.

and if it does fail, please don't suppot it. But I figured out the cause of my problem- I had to add "gid-index" option in my program because I'm using RoCE.

Thanks.

how this state machine correlates with IB QP state machine and how this is reflected by modify_qp verbs ? Ibv_create_qp If you must read the data from one side without any read from the device, maybe RDMA Read isn't the right approach (maybe cache the data in local memory and perform The QP will send packets from this QP as a responder (i.e: data, acks and nacks).

So, I guess this is probably an issue with Soft-iWARP. In one of my experiments I am using only one retry and timeout 10 (4194.304 usec). However, new Work Requested won't be processed. Rdma Cm Do you know why this takes all this time?

In the remote side everything is normal when these errors happen. I'll add this note on RoCE, so people won't fail on it again... Work Requests in both send and receive queues will be processed. Yes, this is possible.

Not all devices support alternate paths. The argument attr is an ibv_qp_attr struct, as defined in . In other words, can one be sure in such a case, that a single RDMA Read request will never cause double read of any remote location?

This may have caused other processes in the application to be terminated by signals sent by mpiexec (as reported here). -------------------------------------------------------------------------- -- I can get around this by adding the "--mca We've downloaded the Linux-x86_64-ibverbs compiled version of namd 2.8 as well as others. If you have the setup, can you try testing with master branch code with below patches applied. (apply the patches in order). Can we totally disable this functionality by setting retry_cnt=rnr_cnt=0?

Thanks for the feedback :) Well, I'll try to answer from my understanding of this document (maybe I'm wrong here; I'm not an iWARP specialist). Thanks Dotan Reply Adrian says: March 23, 2015 Hi Dotan, I've just started with verbs and when I try to modify a qp from INIT to RTR state, a 101 error I hope that I answered your question.
