Scenario: I have two machines, a client and a server, connected with Infiniband. The server machine has an NVIDIA Fermi GPU, but the client machine has no GPU. I have an application running on the...

Is there any utility like tcpdump in Linux for capturing the traffic which is going over RDMA channel? (Infiniband/RoCE/iWARP)

I'm trying to build and run the RDMA examples here. But because I'm just exploring, I don't have any hardware capable of managing RDMA. I get errors like this when I try to run the example code. ...

"DMA" here means: Direct memory access, and "RDMA" is: remote direct memory access. I used Java to created an application to transfer stock data, but I found the latency is bigger than I expected....

I have basic understanding of both JSOR and jVerbs. Both handle limitations of JNI and use fast path to reduce latency. Both of them use user Verbs RDMA interface for avoiding context switch and p...

I am writing an RDMA (InfiniBand) kernel module. Up to now I have been successful creating the protection domain, completion queues for send and receive queues. But whenever I try to create the Q...

My group (a project called Isis2) is experimenting with RDMA. We're puzzled by the lack of documentation for the atomicity guarantees of one-sided RDMA reads. I've spent the past hour and a half hu...

I heard about that RDMA reads and writes are implemented like, when requests come the nic find the physical page and then using DMA to get the data to nic and then to the target. This is straightf...

How can I copy blocks of memory from one server to another under windows using RDMA? We don't have infiniband, but we do have 10gb network switches. All I need is an example, but I'm not having muc...

I'm writing a multi-threaded OpenMPI application, using MPI_Isend and MPI_Irecv from several threads to exchange hundreds of messages per second between ranks over InfiniBand RDMA. Transfers are i...

Assuming I would like to avoid the overhead of the linux kernel in handling incoming packets and instead would like to grab the packet directly from user space. I have googled around a bit and it s...

I have a few multi-core computers connected by Infiniband network. I would like to have some low-latency computation on a pool of shared memory, with remote atomic operations. I know RDMA is the wa...
