openmpi-1.8-1.8.1-5.el6.x86_64 ^^^ ^^^ The name looks really weird. Is it necessary to duplicate '1.8' in the name?

In the N-V-R.A string "openmpi-1.8-1.8.1-5.el6.x86_64" the components are: Name: openmpi-1.8 Version: 1.8.1 Release: 5.el6 Arch: x86_64 The name of the binary package really is "openmpi-1.8". This is intentional. We ship more than one compat version of openmpi and we have to distinguish them by the name. See my comment at: https://bugzilla.redhat.com/show_bug.cgi?id=1158864#c11 The latest version of openmpi in RHEL6.8 is called "openmpi-1.10". I am aware this will need proper release notes. Or is it truly necessary for the package to be called "openmpi"?

But as you see 'rpm -q openmpi' and 'yum install openmpi' conflict with each other when openmpi-1.8 installed. There should be same issue while openmpi-1.10 installed.

There should be same > issue while openmpi-1.10 installed. In the 'yum install openmpi' command, the 'openmpi' is a provide name, not necessarily a package name. 'openmpi-1.8' provides 'openmpi', hence yum try to install 'openmpi-1.8'. The package naming here is a bit unusual, but it's valid by RPM rules.
