Compiler Parallelization Techniques for Tiled Multicore Processors
Recently, tiled multicore processors have been proposed as a solution to provide both performance and scalability. Unlike conventional multicore processors, tiled microprocessors provide on-chip networks to exploit fine-grained parallelism. However, the performance of tiled microprocessors largely depends on compilers because of their relatively simple hardware; exploitation of parallelism, com...
متن کاملVictim retention for reducing cache misses in tiled chip multiprocessors
This paper presents CMP-VR (Chip-Multiprocessor with Victim Retention), an approach to improve cache performance by reducing the number of off-chip memory accesses. The objective of this approach is to retain the chosen victim cache blocks on the chip for the longest possible time. It may be possible that some sets of the CMPs last level cache (LLC) are heavily used, while certain others are no...
متن کاملRuntime home mapping for effective memory resource usage
In tiled Chip Multiprocessors (CMPs) last-level cache (LLC) banks are usually shared but distributed among the tiles. A static mapping of cache blocks to the LLC banks leads to poor efficiency since a block may be mapped away from the tiles actually accessing it. Dynamic policies either rely on the static mapping of blocks to a set of banks (D-NUCA) or rely on the OS to dynamically load pages t...
متن کاملOn exponent matrices of tiled orders
A ring Λ is called a tiled order if Λ is a prime Noetherian semi-prefect semi-distributive ring with non-zero Jacobson radical. Any tiled order can be constructed from a (non-necessarily commutative) discrete valuation ring and an exponent matrix. The latter means a square integer matrix A = (αps), whose diagonal entries are equal to zero, and for all possible indices i, j, k, the following ine...
متن کاملA Tiled Order of Finite Global Dimension with No Neat Primitive Idempotent
Let R be a discrete valuation ring with a unique maximal ideal πR and a quotient field K, and let F = R/πR be the residue class field. Let n ≥ 2 be an integer and {λij | 1 ≤ i, j ≤ n} a set of n integers satisfying λii = 0, λik + λkj ≥ λij , λij + λji > 0 (if i = j) for all 1 ≤ i, j, k ≤ n. Then Λ = (πijR) is a basic semiperfect Noetherian R-subalgebra of the full n× n matrix algebra Mn(K). We ...
