LHC was a motivation for Grids in the same way that CERN's problem of sharing files was a motivation for Sir TBL to create the Web. But, being a motivation does not mean you invented or "pioneered" the freaking stuff. Grids were around in many forms waaaay before CERN decided to go for it.
If anything CERN has achieved in Grids, it is to stunt its growth. It sucked a huge amount of funding from EU for the LCG (LHC Computing Grid) is huge. The LCG is a grid designed by and for control freaks. Many sensible design features (distributed control, proper resource allocation and scheduling, transaction safety, fairness among users) for distributed systems were left out of the LCG. Why? Because it was primarily designed by fucking physicists with a lot of money and who thought they knew waaaay more than computer scientists.
It's no wonder that the industry lost its patience with the grid community and went on to clouds. That's what grids could've been.
Hey CERN, here's a message. Why don't you limit yourselves to claiming credit for physics stuff while computer scientists take distributed systems forward. Fucking morons taking credit for inventing the Web and pioneering Grids. Bah!
