Key Issues,Colin Cunningham Chair, Opticon Key Technology Network,Are we repeating mistakes of history?,CCD controllers?,Hardware-independent software is it achievable?,Is OpenCL the answer? Dubious Not yet ready? But worth looking at Other suppliers are following in line (AMD etc) 10-20% performance hit Need to wait for maturity What will happen in the next few years,Balance CPU/FPGA/GPU/NBT,NBT next big thing Someone has to come up with something to fit most peoples needs Communication FPGAs and CPUs on same die Socket fillers Computation Software bloat? Optimising algorithms for parallelisation Finding bottlenecks Compiler optimisation Assembly?,Can we build a community?,Develop or use common tools DARC? SPARTA? Set standards Negotiate with industry Share best (and worst!) practice E.g. CCD world email list? CfAO fall retreat,What common tools and standards do we need?,Bench marks Common benchmark e.g. Whetstone? 2 types: Has to perform from AO point of view (equal to MVM MAP) Better computationally Different systems will have different metrics Library of algorithms Wiki AO Definitions e.g. Latency (includes settling time? Camera readout?) Turbulence Test Data Well defined datasets for benchmarking with IP cores for FPGAs Make open source? No warrenty OpenCores, openFPGA communities ?,Can we work with other communities?,Radio astronomy ALMA SKA Invite to future workshops Games Scope here Other with similar requirements Low-latency/high frequency trading? HPC Cyber security Image processing Machine vision Continental power transmission Fusion community Navigation systems? ?,Who can coordinate?,In Europe ESO OPTICON Worldwide SPIE$ ? Students? A committee of people. ACTION,Ideas for future workshops,Algorithms Deformable mirrors and associated technology What hardware (FPGA) are people using? Demonstrations Lessons learned Current AO systems Benchmark problem and then a (competitive?) session based around this? If it doesnt work, dont turn up? People showing Hermine how on-sky results have been used to verify models One button operation From proof of concept to operational availability Systems engineering ?,Gaps in Technology?,Low latency communication everywhere With high throughput High memory bandwidths 100GHz CPUs Quantum computing Linux GPU tools FPGA openCL High level programming tools for FPGAs that give reasonable performance As good as hand coded. Magic mapping tools C - FPGA Direct access to GPUs As a community. Parallel competent high level languages,Or should we just wait to see what comes next?,Especially for ELTs? NBT is now in the lab somewhere? Analogue computing?,Specific Actions,What,Who,
