[Mvapich-discuss] Avoid linking to libXNVCtrl.so

[Rahaman, Ronald O]

Hi all,

I need to build MVAPICH2 on a dev server with a GPU; and then deploy it to a prod cluster where many nodes do not have GPUs.  However, when I build on the dev server, MVAPICH2 is linked to the available libXNVCtrl.so.  Thus on the GPU-less nodes on prod cluster, there are load-time errors since libXNVCtrl.so is not available.

Is there a way to configure MVAPICH so it will not link to libXNVCtrl.so?

I already have `--disable-cuda` set when I configure.  If I need to build and deploy a differently-configured hwloc, I can definitely manage that.

Many thanks,
Ron
