Abstract
Provided are a parallel processing system and an operation method thereof. The parallel processing system includes: a bus; a plurality of parallel processing processors; a plurality of shared memories connected to the bus via separate individual channels and connected to each other via a memory connection line; and a main processor configured to set a broadcasting state for the plurality of shared memories and control data stored in one shared memory among the plurality of shared memories to be broadcast to another shared memory via the memory connection line according to the broadcasting state.
Claims15
A parallel processing system comprising:
- a bus;
- a plurality of parallel processing processors;
- a plurality of shared memories connected to the bus via separate individual channels and connected to each other via a memory connection line;
- and
- a main processor configured to:
- set a broadcasting state for each of the plurality of shared memories, the broadcasting state being one of an owner state, a destination state, a forward state, a bypass state, or a no broadcasting state, and
- control data stored in a first shared memory of the plurality of shared memories, the first shared memory being in the owner state, to be broadcast to a second shared memory, the second shared memory being in the destination state, via the memory connection line according to the broadcasting state.
An operation method of a parallel processing system, the operation method comprising:
- setting a broadcasting state for each of a plurality of shared memories connected to a bus via separate channels and connected to each other via a memory connection line, the broadcasting state being one of an owner state, a destination state, a forward state, a bypass state, or a no broadcasting state;
- and
- broadcasting data stored on a first shared memory of the plurality of shared memories, the first shared memory being set to the owner state, to a second shared memory, the second shared memory being set to the destination state, via the memory connection line, according to the broadcasting state.
