DESCRIPTION:This demo introduces Reptiles - Repeated Tiles of Sargantana\, 
 an open-source RISC-V multicore architecture designed to support research 
 in HPC systems. Reptiles builds upon the OpenPiton manycore framework by i
 ntegrating multiple Sargantana RISC-V cores and enhancing the memory hiera
 rchy and interconnection network to improve scalability and performance. T
 he goal is to provide an accessible and flexible platform for researchers 
 to develop\, experiment with\, and optimize HPC workloads using open hardw
 are.\n\nReptiles replicates Sargantana tiles within OpenPiton’s architec
 ture and introduces several architectural improvements. These include a co
 nfigurable network-on-chip width (from 64 up to 704 bits)\, flexible cache
  block sizes\, adjustable numbers of miss status holding registers (MSHRs)
 \, improved cache sizes and associativities\, parallel SRAM access in the 
 L2 and the last-level cache\, and configurable number of memory controller
 s. The system also integrates the High-Performance Data Cache (HPDcache) a
 s an L1 data cache and enhances the Sargantana core with broader support f
 or RISC-V extensions\, particularly the RISC-V Vector Extension (RVV 1.0).
  Additional improvements include debugging support\, performance counter a
 ccess in Linux\, and enhanced RTL simulation features such as checkpointin
 g.\n\nIn this demo we show a fully functional FPGA prototype of Reptiles w
 ith four Sargantana cores booting Linux and running OpenMP benchmarks such
  as the NAS Parallel Benchmarks\, interactive UART console games\, and gra
 phical applications by performing X11 forwarding over SSH. Overall\, Repti
 les demonstrates that open-source RISC-V multicore systems can effectively
  support scalable HPC research and experimentation.
