Method for Error Logging

摘要

Error data is read from error registers and written into a buffer. A computing node uses a BIOS to read the error data, rearm the error register and write the data into a memory mapped buffer. A hub chip supports creation of a shared memory system of computing nodes. A management controller in the computing node extracts error data from the buffer. The error data preferably consists essentially of the error register identifiers and the contents of the error registers. A system management node receives the error data from the management controllers in the computing nodes. The system management node may be coupled to but separate from the computing nodes.

1. A method for logging errors in a hardware architecture operating a plurality of physically separate computing nodes, the method comprising:
generating an error interrupt within one of the computing nodes; reading, in response to the error interrupt, error registers within the computing node; writing error data from error registers to a memory mapped buffer within the computing node; and sending the error data from the buffer to a repository accessible to an error analyzer in the hardware architecture coupled to but separate from the plurality of computing nodes.
