Table 3 Definitions of timing components.
From: A multi-GPU enabled solver in Kronecker product form for multiphysics problems
Symbol | Definition |
|---|---|
\(T_{dt}\) | Time for buffer allocation, host-device data transfer, and pre-mapping (Algorithm 6). |
\(T_{Kx}\) | Execution time for SpMV in Kronecker product form, excluding communication. |
\(T_{c}\) | Time spent on communication in SpMV in Kronecker product form. |
\(T_{Gn}\) | Time for Gram-Schmidt orthogonalization and normalization. |
\(T_{all}\) | Overall runtime. |
