Plasma shared memory
WebThe Plasma object store lives as a separate process to which clients of the store may commit and ’seal’ data objects with an object identifier. The store manages the objects’ locations in shared memory and makes them available to other clients upon sealing. Sealing an object prompts the store to make WebMar 6, 2014 · The performance and productivity gain on the three-node system with a hybrid process-thread configuration (case 6×4) is more than twice as good as the performance on a single shared memory node (case 1×8). It is also almost 30% better than the completely distributed model (case 24×1), which uses the same number of cores.
