Intel Labs has created an experimental “Single-chip Cloud Computer,” (SCC) a research microprocessor containing the most Intel Architecture cores ever integrated on a silicon CPU chip – 48 cores. It incorporates technologies intended to scale multi-core processors to 100 cores and beyond, such as an on-chip network, advanced power management technologies and support for “message-passing.”
One of the most important aspects of the SCC’s network fabric architecture is that it supports “scale-out” message-passing programming models that have been proven to scale to 1000s of processors in cloud datacenters. Though each core has 2 levels of cache, there is no hardware cache coherence support among cores in order to simplify the design, reduce power consumption and to encourage the exploration of datacenter distributed memory software models, on-chip. Intel researchers have successfully demonstrated message-passing as well as software-based coherent shared memory on the SCC.
