Intel, NVIDIA Take Shots At CPU vs. GPU Performance
MojoKid writes "In the past, NVIDIA has made many claims of how porting various types of applications to run on GPUs instead of CPUs can tremendously improve performance — by anywhere from 10x to 500x. Intel has remained relatively quiet on the issue until recently. The two companies fired shots this week in a pre-Independence Day fireworks show. The recent announcement that Intel's Larrabee core has been re-purposed as an HPC/scientific computing solution may be partially responsible for Intel ramping up an offensive against NVIDIA's claims regarding GPU computing."
So, once upon a time, there was this text editor called vi.
To make it do shit you type in cryptic commands. The one for search-and-replace is s, followed by a slash, followed by the thing you want to search for, followed by another slash, followed by the thing you want to replace it with. Because of more arcana, this will only happen once per line unless you put a g after it.
So s/cat/dog/g means "replace all occurrences of cat with dog".
Incidentally, you also have to tell vi in what range it should do this operation. So you get cryptic commands like :1,$s/cat/dog/g
