High-performance distributed computing systems increasingly feature nodes that have multiple CPU sockets and multiple GPUs.
|
||||
The communication bandwidth between these components is non-uniform.
|
||||
Furthermore, these systems can expose different communication capabilities between these components.
|
||||
For communication-heavy applications, optimally using these capabilities is challenging and essential for performance.
|
||||
Bespoke codes with optimized communication may be non-portable across run-time/software/hardware configurations, and existing stencil frameworks neglect optimized communication.
|
||||
This work presents node-aware approaches for automatic data placement and communication implementation for 3D stencil codes on multi-GPU nodes with non-homogeneous communication performance and capabilities.
|
||||
Benchmarking results in the Summit system show that choices in placement can result in a 20% improvement in single-node exchange, and communication specialization can yield a further 6x improvement in exchange time in a single node, and a 16% improvement at 1536 GPUs."""
