Computers versus Brains; Computers are good at storage and speed, but brains maintain the efficiency lead by Mark Fischetti SciAm October 25, 2011 99.181.138.228 ( talk) 05:13, 2 November 2011 (UTC)
I'm sure it's supposed to be computer node but still, what is it referring to? Nodes can be any number of things in computer terminology. Muleattack ( talk) 22:36, 21 January 2012 (UTC)
minecraft will still lag as hell... — Preceding unsigned comment added by 92.247.136.18 ( talk) 18:28, 5 March 2012 (UTC)
There seems to be confusion over the number of racks and CPUs, but if you look at the Japanese page, it specifically says (translated into English). Note there were two LINPACK tests in June and November and in each test, the number of racks and CPUs are different because in June, when it hit it's first record, the supercomputer was still under construction:
On June 20th, the LINPACK benchmark was executed for 28 hours using 672 racks (68,544 CPUs), which was in the middle of installation, and as a result, 8.162 petaflops with an execution efficiency of 93.0% was achieved. . As a result, it was ranked TOP500 [5].
On November 2, the LINPACK benchmark recorded 10.51 petaflops (floating point arithmetic at 1.051 times per second) with an execution efficiency of 93.2% (LINPACK result 10.51PFLOPS/theoretical efficiency 11.28PFLOPS), announced that it had achieved its initial performance goal. This is the final configuration consisting of 864 racks (88,128 CPUs), and completed the installation and testing of LINPACK benchmarks for 29 hours and 28 minutes on October 7th to 8th to confirm their basic operation and design performance. This is the result of running the program and measuring. [76].
