Reply Dotan Barak says: July 8, 2015 Hi Elena. retransmission, violation, etc.), maybe this flow isn't fully tuned. I'll add this note on RoCE, so people won't fail on it again... this contact form

SQD state In order to move to this state, one must call ibv_modify_qp() from the RTS state. struct ibv_qp_init_attr qp_init_attr; memset(&qp_init_attr, 0, sizeof(qp_init_attr)); qp_init_attr.qp_type = IBV_QPT_RC; qp_init_attr.sq_sig_all = 1; qp_init_attr.send_cq = conn.cq; qp_init_attr.recv_cq = conn.cq; qp_init_attr.cap.max_send_wr = DEFAULT_CQ_SIZE / 2; qp_init_attr.cap.max_recv_wr = DEFAULT_CQ_SIZE / 2; qp_init_attr.cap.max_send_sge = std::min((int)MAX_SGE, Any QP can be transitioned to Reset or Error state by calling ibv_modify_qp() from any state.

Are you using explicit ibv_modify_qp(() or do you call librdmacm function? Value can be [1..dev_cap.max_sge] max_recv_sge The maximum number of scatter/gather elements in any Work Request that can be posted to the Receive Queue in that Queue Pair. The value of the entry in the P_Key table that outgoing packets from this QP will be sent with and incoming packets to this QP will be verified within the Primary

Finally, we reinstall the OFED drivers and it works. Value can be [1..dev_cap.max_sge]. The following tables indicate for each QP Transport Service Type, the minimum list of attributes that must be changed upon transitioning QP state from: Reset --> Init --> RTR --> RTS.

Init state Description In order to move to this state, one must call ibv_modify_qp() from Reset state. go to this web-site Mellanox say that this GID specification is a new option.

No packets will be sent from this QP. I've tried recompiling charmrun, using the current version that I also obtained with the namd source.

Are you using IB or RoCE? weblink Typically, I'm able to successfully complete thousands of requests before the failure occurs (actually, the application often finishes without errors). I listed my code here: struct ibv_qp_attr attr; int qret; attr.retry_cnt = (uint8_t)7; attr.timeout = (uint8_t)14; attr.rnr_retry = (uint8_t)7; qret = ibv_modify_qp(id->qp, &attr, IBV_QP_RETRY_CNT|IBV_QP_TIMEOU T|IBV_QP_RNR_RETRY); Thanks Reply Dotan Barak says: October Thanks Dotan Reply Adrian says: March 24, 2015 I'm using IB and explicit ibv_modify_qp() Dotan Barak says: March 24, 2015 It is weird; since this return value isn't really returned ...

For that, we have two nodes, the first node has XenServer 6.2 dom0 and the second node has CentOS 6.4. If the destination is in another subnet, the LID of the Router sl 4 bits.

All subsequent Work Requests in that queue and all Work Request in the other queue and new Work Requests posted to both of the queues will be flushed with error. Thank you for your time. The TCP versions run, but the ibverbs version fails. Rdma Cm It can be one of the following enumerated values:

In Infiniband, you should perform path query to the SA or use CM or CMA, in iWARP, you should use the CMA ibv_modify_qp() failed, what are the attributes of that QP method : Ethernet--------------------------------------------------------------------------------------- local address: LID 0x1b QPN 0x0866 PSN 0x301c00 remote address: LID 0x13 QPN 0x0064 PSN 0x86e97eethernet_read_keys: Couldn't read remote address Unable to read to socket/rdam_cmFailed to exchange data Explicit ibv_modify_qp call to change QP state to RTR fails and returns 101. (My code is based on ibv_rc_pingpong program, an example from libibverb library. In my case the responding side (where the device is) must remain as passive as possible.

If (in your experience) the link will be stable until the last retransmission, ib_write_lat will continue working.. qperf supports 4k MTUs just fine, however the MTU on the given device is limited to whatever the device and switch are set to. In the remote side everything is normal when these errors happen. RQ Logic receives duplicate copy of request.

The QP will send packets from this QP as a responder (i.e: data, acks and nacks).
