A fault-tolerant distributed subcube management scheme for hypercube multicomputer systems Academic Article uri icon

abstract

  • This paper proposes a fault-tolerant distributed subcube management scheme for hypercube multicomputer systems. Gracefully degradable subcube management is supported by a data structure, called the distributed subcube table (DST), and a fault-tolerant broadcast protocol, called the reliably synchronized broadcast (RSB). In an n-dimensional hypercube, DST is the collection of 2" local subcube tables (LSTs), dst= {lst0,LST1,., LST2”-1}, where LSTXis a bit-mapped table assigned to Nx, a fault-free node whose address is x. LSTX, Vr, is n +1 bits long, and it records the status (free/busy) of certain subcubes adjacent to Nx. The RSB diagnoses and avoids faults during interprocessor communication to prevent faulty nodes from being allocated for job execution. In addition to possessing a fault-tolerant design, our scheme can also achieve comparable or better performance than existing centralized schemes, as verified by extensive simulation. © 1995 IEEE
