A segmentation fault occurs when a program attempts to access a memory location that it is not allowed to access, or attempts to access a memory location in a way that is not allowed (for example, attempting to write to a read-only location, or to overwrite part of the operating system)
A "Memory access fault by GPU node-15" error usually indicates a problem where a program is trying to access memory that either doesn't exist or is not accessible to it, often related to the GPU. This can be due to various reasons, including memory errors, incorrect code, or issues with the GPU drivers or the application itself
