BARHGGPUALG

Description
Defines the GPU algorithm choice. The Nvidia linear algebra libraries offer various ways to calculate matrix-vector products. Some of these require more memory, but offer deterministic execution. On the other hand, there is a limited memory option, but with nondeterministic execution.
Type
Integer
Topic area
Primal Dual Hybrid Gradient
Values
0 
The selected algorithm ensures deterministic runs on GPU.
1 
Use a faster GPU implementation that may result in nondeterministic runs.
2 
Use a reduced memory version on GPU, which may result in nondeterministic runs.
3 
Use a faster and reduced memory implementation on GPU, which may result in nondeterministic runs.
Default value
0
Affects routines
XPRSlpoptimize ( LPOPTIMIZE).
