Abstract: A high-performance computing (HPC) framework for accelerating sparse Cholesky factorization on field-programmable gate arrays (FPGAs) is provided. The proposed framework includes an FPGA kernel implementing a throughput-optimized hardware architecture for accelerating a supernodal multifrontal algorithm for sparse Cholesky factorization. The proposed framework further includes a host program implementing a novel scheduling algorithm for finding the optimal execution order of supernode computations for an elimination tree on the FPGA to eliminate the need for off-chip memory access for storing intermediate results. Moreover, the proposed scheduling algorithm minimizes on-chip memory requirements for buffering intermediate results by resolving the dependency of parent nodes in an elimination tree through temporal parallelism.

Abstract: Hardware-agnostic accelerator orchestration (HALO) provides a software framework for heterogeneous computing systems. Hardware-agnostic programming with high performance portability is envisioned to be a bedrock for realizing adoption of emerging accelerator technologies in heterogeneous computing systems, such as high-performance computing (HPC) systems, data center computing systems, and edge computing systems. The adoption of emerging accelerators is key to achieving greater scale and performance in heterogeneous computing systems. Accordingly, embodiments described herein provide a flexible hardware-agnostic environment that allows application developers to develop high-performance applications without knowledge of the underlying hardware.

Abstract: A software-defined board support package (SW-BSP) for stand-alone reconfigurable accelerators is provided. The adoption of emerging accelerators is key to achieving greater scale and performance in heterogeneous computing systems. A stand-alone accelerator protocol (SAP) allows for a hardware accelerator to be plug-and-playable in a stand-alone fashion (without needing a local central processing unit (CPU) host) and interact with a remote computing system agent for application acceleration across any network infrastructure. The SAP further facilitates a hardware-agnostic accelerator orchestration (HALO) software framework for hardware-agnostic programming with high performance portability and scalability in heterogeneous computing systems. The SW-BSP provides an implementation of the SAP on reconfigurable accelerators.
