Info

Will it be too Hard to Use GDR?• No• You need to first install the OFED-GDR driver from Mellanox• Install MVAPICH2-GDR• Current GPU-aware features in MVAPICH2 are triggered witha runtime parameter: MV2_USE_CUDA=1• To activate GDR functionality, you just need to use one moreruntime parameter: MV2_USE_GPUDIRECT =1• A short demo will be shown now to illustrate the easy usageof MVAPICH2-GDRMVAPICH2 with GPUDirect RDMA19
