Data Type

Integer

Default Value

0

Description

This parameter provides the option to NOT pin host memory. The following options are available:

  • 0, Pin host memory when GPUs are used.
  • 1, Do NOT pin host memory when GPUs are used.

Pinning host memory improves transfer rates to/from the GPUs. It allows the transfers to occur without locking and unlocking each page during the transfers. For this reason it is selected as the default.

If a machine is being heavily used for other tasks, it may not be possible to pin the required memory. Under these conditions this Parameter may be used to skip memory pinning.
