I want to use infiniband, I am from a University in the US, my University's
high performance center don't have Gcc compiled openmpi that support
infiniband, so I want to compile myself.
But I have a few questions,
1. Is it ok to compile openmpi myself with infiniband support, if I
don't have the root privilege? Is it going to work?
2. If it is ok, how can I find out where is the infiniband installation
directory, any shell command to show it?
3. Which configuration is correct? For example, using
"--with-openib=/usr/include/infiniband" as told in openmpi FAQ, or I need to
use "--with-openib=/usr/include/infiniband --with-openib-libdir=/usr/lib64"
Thanks so much.
