Paper on what a Xen+FPGA cloud would look like at FCCM. This work with Satnam Singh explored reconfigurable data processing for clouds, addressing how FPGAs could help solve practical problems in scaling out data-centers where computation is limited by energy consumption or latency. We identified the prerequisites for making reconfigurable computing practical in cloud environments and described scenarios enabled by combining virtualization with hardware acceleration. The paper laid groundwork for thinking about heterogeneous computing in the cloud era.
