AW: [mvapich-discuss] mvapich libraries error

[Winkler, Ursula (ursula.winkler at uni-graz.at)]

No, I did not update the kernel and the software was compiled exact for the running kernel. 
But nevertheless infiniband had to be installed new and added with mlnx_add_kernel_support.

Thanks for your help
