MPSS upgrade removes opencl mic packages

[Scott_S_Intel2]

I updated to the latest MPSS installation for RHEL 6.3, and found that OpenCL programs no longer worked. Uninstalling the previous version of MPSS, I executed the following command: sudo yum remove --noplugins --disablerepo=* intel-mic\*. I now realize that the following OpenCL packages were inadvertently removed:

Erasing : opencl-1.2-intel-mic.x86_64      2/12
Erasing : opencl-1.2-intel-mic.x86_64      3/12
Erasing : opencl-1.2-intel-mic.x86_64      4/12

I recommend editing the README installation notes to remove packages named "intel-mic-/*" perhaps.

MPSS versions have come so fast I have no clue which is latest.  For some of the more recent ones there is an uninstall script which might bear examination on this point.

Hi Scott, the MPSS team indeed validated this problem:

the command line in the readme file was constructed under the assumption that specifying “intel-mic\*” would match rpms that only START with name intel-mic.  However, it appears that yum is matching ANY rpm with “intel-mic” in the name.  

A simple but effective solution to this problem is to use the following line instead to uninstall any 2.1 based MPSS version without removing other rpms with the “intel-mic” string in them:

 $ sudo rpm -e `rpm -qa | grep ^intel-mic`

I'm asking if any future revs of the 2.1 release readme can be amended with the above command; additionally I was told that the next major release (MPSS 3.1) won't experience this issue.
