Development of a routing/switching mechanism for a Compute Node system — •Sören Fleischer1, Wolfgang Kühn1, Jens Sören Lange1, Thomas Geßler1, David Münchow1, and Hao Xu1,2 — 1II. Physikalisches Institut, Uni Giessen — 2IHEP, China
Our group is currently developing an ATCA based system of compute nodes (CN), which is proposed for data readout and online data processing at PANDA and the BELLE-2 PXD. Each CN is equipped with 4 Virtex-5 FPGAs running algorithm IP cores. In order for these cores to communicate with each other over RocketIO and/or serial link, a routing and switching mechanism is to be developed. The system should automatically recognize the map of the network as well as changes to it and build/update the routing information accordingly.
Management of the routing information will be done using a computer connected to the ATCA shelf managers over ethernet to retrieve information about which algorithm IP cores are present in which location, and to update the switch IP cores’ routing/forwarding tables.
