Monitoring memory module parameters in high performance computers

摘要

Monitoring parameters of memory modules is described. According to certain embodiments, one or more parameters on respective memory modules are monitored. Corresponding parameter information is transmitted from the respective memory module to a device that is external to the respective memory modules.

1. A method comprising:
detecting one or more input signals associated with one or more memory modules by using a differential pair of transistors configuration housed on a respective memory module of the one or more memory modules, the differential pair of transistors configuration being coupled between a power supply and ground potential and coupled to an output node; generating, by using the differential pair of transistors configuration, one or more output signals based on at least a subset of the detected one or more input signals; using a voltage divider coupled to a base of a second transistor of the differential pair and operable to provide as a reference signal a programmable reference voltage between zero and an operating voltage of the respective memory module, and a first transistor of the differential pair coupled to the power supply; using a first resistor configurable to be coupled to the base of the second transistor and the voltage divider; using a second resistor configurable to be coupled to the base of the second transistor, and further coupled to a preselected reference voltage, wherein the first resistor is installed when the programmable reference voltage is applied; and wherein the second resistor is installed when the preselected reference voltage is applied; routing the one or more output signals to an area external to the associated one or more memory modules; and generating a first parameter information based on the one or more output signals, wherein the first parameter information is indicative of activity on the associated one or more memory modules, and wherein the area external to the associated one or more memory modules is only for enabling display of the first parameter information.
