RUNNING GPUMODESWITCH  

gpumodeswitch

 supports two operations: listing the current mode of GPUs in the 

platform, and changing the mode of individual or all GPUs. 

When running on Linux, 

gpumodeswitch

 requires root permissions. 

When running on Windows, 

gpumodeswitch

 requires administrator permissions (see 

Figure 2 on page 11), and the 

nvflsh64.sys

 driver should be in the same directory as 

the 

gpumodeswitch

 executable.

Listing current GPU modes 

To list the current mode of all GPUs in the system, use 

--listgpumodes

# gpumodeswitch --listgpumodes

Log file output 

The 

--listgpumode

 

command also writes GPU mode information to a log file named 

listgpumodes.txt

. By default 

gpumodeswitch

 

creates the log file in the current
