The Register: SGI to enable 64-way Linux multiprocessing with ccNUMA

“SGI is to port a version of its ccNUMA shared-memory
multiprocessing technology to Linux to boost efforts centred on
solve the open source OS’ inability to operate efficiently on
machines with eight or more processors.”

SGI’s contribution will focus on improving Linux
installations that will run on Intel’s upcoming 64-bit Itanium chip
and allow it to work on up to 64 of the next-generation
processors.

“Right now, Linux scales readily to four processors, but getting
it to run well on eight is rather trickier.”
