<div dir="ltr"><div><div><div><div>Hi all,<br></div><br></div> I am new to InfiniBand, and writting an application(using OFED-1.5.4) for Mellanox HCA InfiniHost Ex25208 (board_id : HP_0060000001), which registers 16GB memory using
ibv_reg_mr but it is failing (returns NULL).<br>My machine have sufficient memory (64 GB) and i am able to register less than 16GB. <br>Is it the HCA which is limiting this and if yes, is there any way to find out maximum memory that can be registered.<br>
I have tried ibv_query_device but it returned max_mr_size as 0XFFFFFFFFFFFFFFFF(16 times).<br><br></div>Thanks<br></div>Jagadeesh<br></div>
