When a large graph contains billions of edges that cannot reside entirely in a computer's main memory, computing and maximizing H-group closeness centrality both become challenging.
The spot price of a 64-megabit D-RAM chip, the main memory in computers, has fallen to less than $3 from a high near $9 in July.
The settlement announced Wednesday involved dynamic random-access memory chips, or DRAMs, which provide the main memory for personal computers.
Revenue from dynamic random access memory chips, the main memory in personal computers, rose almost 24percentt in February from January because prices increased, Mr. Scalise said.
The Justice Department is seeking information about Mitsubishi Electric's sales of DRAM, the main memory in personal computers, from 1998 to 2002, Mitsubishi Electric said.
The Justice Department is investigating whether Micron conspired to fix prices with Infineon Technologies, Samsung Electronics, Hynix Semiconductor and other makers of the chips, which provide the main memory in personal computers.
These approaches do not consider the fact that the data set can be too large and may not fit into the main memory of some computers.
RAM, in fullrandom-access memory, Computer main memory in which specific contents can be accessed (read or written) directly by the CPU in a very short time regardless of the sequence (and hence location) in which they were recorded.
The main memory of a computer is linear, consisting of a sequence of memory cells that are numbered 0, 1, 2,… in order.
An important point to note is that the main memory of a computer provides only temporary storage; any data stored in main memory is lost when the power is turned off.
