| 40 | | To avoid contention when several threads access the same page table to handle TLB miss, ALMOS-MKH replicates the page tables. For each multi-threaded user application P, the Generic Page Table (GPT), and the Virtual Segments List (VSL) are replicated in each cluster K containing at least one thread of the application. According to the "on-demand paging" principle, these replicated structures GPT(K,P) and VSL(K,P) are dynamically updated when page faults are detected. This section describes this building mechanism and the coherence protocol required by these multiple copies. |
