Minimize the performance impact of the device kernel profiling support when the profiler plugin is not loaded. Reduce the overheads of CUDA graph capturing, which increased in NCCL 2.26.2 for large graphs. Fix the exchange of enhanced connection establishment (ECE) options to address potential slowdowns on networks utilizing RoCE. Test if cuMem host allocations work and if not, disable them. Enabled by default since NCCL 2.24 if the CUDA driver version is at least 12.6, such allocations rely on NUMA support, which is by default not available under Docker. We recommend invoking Docker with "--cap-add SYS_NICE" to enable it. Fix an initialization error when running with NCCL_NET_GDR_C2C=1 on multiple MNNVL domains with non-uniform network configurations across nodes. Fix the printing of sub-seconds in the debug log when using a custom NCCL_DEBUG_TIMESTAMP_FORMAT setting.
