Hi All Firstly, a big thanks to Parav for solving my “two RNICs in the same server” loopback woes [1]. The script you provided worked a treat with rdma_cm things like rping and NVMe over Fabrics working very nicely. One thing I did notice is that for the perftests (e.g. ib_write_bw) there is no way to bind to an IP address when using the rdma_cm option –R. Does anyone know if this is possible with the existing code? If not I’d like to propose a patch for the perftests but I am not sure where the current upstream repo for perftests is? I also wanted to ask if this is something that could be considered for rdma-core as we have other user-space tools there? A repo for perftests lives here [2] (which Logan forked a while back [3]) but it seems pretty inactive… Cheers Stephen [1] https://marc.info/?l=linux-rdma&m=150575871330293&w=2 [2] git://git.openfabrics.org/~grockah/perftest.git [3] https://github.com/lsgunth/perftest ��.n��������+%������w��{.n�����{���fk��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
