[Mvapich-discuss] Error while using MVAPICH with profiling tools.

[Shineman, Nat]

Having discussed with the user offline we discovered that their instance of MVAPICH2 was not configure with pvars enabled. Setting "--enable-mpit-pvars" at configure time resolved the issue. We are adding logic to MVAPICH2 to notify users that an installation was not configured with support for mpit-pvars if they attempt to access them on an unsupported build.

Subject: [Mvapich-discuss] Error while using MVAPICH with profiling tools.

Dear Sir/Ma'am,
PFB the error emitted by the MVAPICH2 while using the profiling tools ( specifically for MPI_T). MVAPICH2 is working fine without the profiling tool. Please help me in this regard.
Thank you for your time and consideration.
