The Single Chip Cloud Computer s a 48-core concept vehicle created by Intel Labs and used by hundreds of researchers worldwide for many-core software innovation. Software Managed Coherence (SMC) for SCC provides a shared virtual memory space for processor cores in the SCC. The SMC research software explores solutions to several many-core challenges. First, it is becoming more difficult to design and verify efficient hardware memory coherence for many-core processors as core counts scale to 10s-100s fo cores. Also, when multiple applications run on a single many-core chip it may require coherence support on the cores they are running on, but likely not between the applications. SMC enables dynamically reconfigurable coherence domains which is difficult to support with a hardware-only implementation. Lastly, hardware coherence is complex for heterogeneous platforms like combined CPU-GPU systems. Software Managed Coherence could make better use of silicon, efficiently support emerging applications, dynamically reconfigure coherence domain, and most importantly, still be able to provide performance comparable to hardware coherence.
The software is available as an anonymous export from the SCC public SVN.
