#NVIDIA CHECKING SYSTEM COMPATIBILITY STUCK HOW TO#

Tool is used to collect logs from the system that are relevant for $ sudo /usr/local/cuda/gds//tools/gdstools/gds_log_collection.py -h

Per process information like cufile.log,.

IB devices info like ibdev2net and ibstatus.

dmesg Output and relevant kernel log files.

Some of the important information that this tool captures is Relevant debugging information from the system when issues with GDS IO are Gds_log_collection.py, may be run by GDS users to collect
