Title:

Nanoprocessor Cluster: Conversion from ILP to uTLP

Abstract:

Now a multi-many-core processor is one of the most popular way to achieve high-performance. In order to realize the potential performance of the multi-many cores, we must extract task or thread level parallelism (TLP) by dividing a program into multiple threads loosely coupled each other. Tightly coupled operations must be in a single thread to avoid the overhead for synchronizations and data transfers. The thread of tightly coupled operations can be parallelized by extracting instruction level parallelism (ILP). However, the ILP extraction is inefficient for long latency operations. I will introduce a "Nanoprocessor Cluster" to convert the ILP to micro-thread level parallelism (uTLP) for the efficient parallelization of such a program with tightly-coupled long-latency operations.
