and at hotchips last week ... ibm decribes being able to plug two power7+ chips into a single socket ... there were references to software licensing gimicks (for licenses based on number of sockets) http://www.theregister.co.uk/2012/08/31/ibm_power7_plus_processors/ from above: Anyway, with a double-stuffed machine, you can in theory get 512 cores into a single system image, but it is not clear if AIX and Linux will be able to see more than 1,024 threads as they currently do; the IBM i operating system tops out at 128 threads in a single image at this point, with a special patch to boost it to 256 threads, and is woefully overdue for the same loving that AIX and Linux have gotten since 2010 to at least see 1,024 threads. ... snip ... i.e. with four hyperthreads per core and 512 cores in a single multiprocessor would yield 2048 hyperthreads (aka the appearance of 2048 processors) -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
