In accordance with some implementations, a method for evaluating large scale computer systems based on performance is disclosed. A large scale, distributed memory computer system receives topology data, wherein the topology data describes the connections between the plurality of switches and lists the nodes associated with each switch. Based on the received topology data, the system performs a data transfer test for each of the pair of switches. The test includes transferring data between a plurality of nodes and determining a respective overall test result value reflecting overall performance of a respective pair of switches for a plurality of component tests. The system determines that the pair of switches meets minimum performance standards by comparing the overall test result value against an acceptable test value. If the overall test result value does not meet the minimum performance standards, the system reports the respective pair of switches as underperforming. |

1. A method for evaluating large scale computer systems based on performance, comprising:
at a large scale, distributed memory computer system having a plurality of switches, wherein each switch is connected to a plurality of nodes, and wherein each node includes one or more processors and memory storing one or more programs for execution by the one or more processors: receiving topology data, wherein the topology data describes the connections between the plurality of switches and lists the nodes associated with each switch; based on the received topology data, for a plurality of pairs of switches in the plurality of switches, wherein each of the pairs of switches includes a first switch and a second switch that connect to each other via direct links, performing a data transfer test for each of the pair of switches, wherein the data transfer test determines overall data transfer performance of a respective pair of switches, including:
transferring data between a plurality of nodes associated with a first switch in a pair of switches and a plurality of nodes associated with a second switch in a pair of switches;determining a respective overall test result value reflecting overall performance of a respective pair of switches for a plurality of component tests, wherein the component tests reflect performance of links between switches and/or performance nodes connected to the switches during the transfer of data; and determining that the pair of switches meets minimum performance standards by comparing the overall test result value against an acceptable test value; and in accordance with a determination that the overall test result value does not meet the minimum performance standards, reporting the respective pair of switches as underperforming. |
