Thanks for the help you all have provided.
There is no where in this thread you mentioned you are learning perl at work and that this is not school work. If it really is not school work then I apologize, but the code you posted is typical school work that I see posted all the time by students. Now if you need further help I am willing to help.
Maybe if you describe what you are trying to accomplish it would help figure out the best way to help you instead of trying to help with bits of code here and there.

rdma_post_recvv
RDMA_POST_RECVV(3) Librdmacm Programmer's Manual RDMA_POST_RECVV(3)
NAME
rdma_post_recvv - post a work request to receive incoming messages.
SYNOPSIS
#include <rdma/rdma_verbs.h>
int rdma_post_recvv (struct rdma_cm_id *id, void *context, struct ibv_sge *sgl, int nsge);
ARGUMENTS
id A reference to a communication identifier where the message buffer(s) will be posted.
context User-defined context associated with the request.
sgl A scatter-gather list of memory buffers posted as a single request.
nsge The number of scatter-gather entries in the sgl array.
DESCRIPTION
Posts a single work request to the receive queue of the queue pair associated with the rdma_cm_id. The posted buffers will be queued to
receive an incoming message sent by the remote peer.
RETURN VALUE
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason.
NOTES
The user is responsible for ensuring that the receive is posted, and the total buffer space is large enough to contain all sent data before
the peer posts the corresponding send message. The message buffers must have been registered before being posted, and the buffers must
remain registered until the receive completes.
Messages may be posted to an rdma_cm_id only after a queue pair has been associated with it. A queue pair is bound to an rdma_cm_id after
calling rdma_create_ep or rdma_create_qp, if the rdma_cm_id is allocated using rdma_create_id.
The user-defined context associated with the receive request will be returned to the user through the work completion wr_id, work request
identifier, field.
