    unable to create QP after set HUGE_RC to y

    xuej

      Hi,

       

      I had a problem since I set HUGE_RC to y in order for HCA to use huge pages for QP and CQ.  It shows up the following error message:

       

      Unable to create QP.

      Couldn't create IB resources

       

      After I remove the environment variable, it works fine again. On my system, I have huge pages of 1GB in size, and the OS reserves 8 such pages.

      I am using ConnextX-3 with mlx4_0.

       

      I am wondering what could be the cause for such errors.

       

      Thanks in advance,

       

      Sam
