For more details on the internal architecture, see the\nREADME.md in the [`pulp` repository](https://github.com/pulp-platform/pulp).\n\nThe [`doc`](doc/) folder contains the draw.io schematic shown above, as well as\nthe raw source to allow for updates, outlining the most important components in\npulp_cluster, as well as the communication interfaces connecting these. While\nnot a complete overview of all signals, this is meant as a slightly more\ndetailed overview that can assist in development. Please be aware that the\nschematic may not be 100% accurate.\n\n## Dependencies\n\nTo *build* the cluster, you will need:\n\n   - Bender `\u003e= 0.24.0`\n   - GNU Make `\u003e= 3.82`\n   - Python `\u003e= 3.9`\n   - RISCV GCC `\u003e= 11.2.0`\n\nWe use [Bender](https://github.com/pulp-platform/bender) for hardware IP and dependency management; for more information on using Bender, please see its documentation. You can install Bender directly through the Rust package manager Cargo:\n\n```\ncargo install bender\n```\n\n## Simulation\n\nIt is possible to run benchmarks on the cluster, either within\n[PULP](https://github.com/pulp-platform/pulp) or as a separate IP. For\nsimulation within PULP, you can directly go to the PULP repo and follow the\nREADME.\n\nTo simulate the cluster on its own, you can perform the following steps:\n\nWarning: requires QuestaSim 2022.3 or newer.\n\n1. Make sure the PULP RV32 toolchain is in your `PATH`. Please refer to [PULP\n   RISCV GCC toolchain](https://github.com/pulp-platform/pulp-riscv-gcc) to use\n   a pre-built release. (At IIS, this is set up by the env script in step 4.)\n\n2. Download the sw stack and bare-metal tests:\n\t```\n\tmake pulp-runtime\n\tmake regression_tests\n\t```\n\n3. Source the environment:\n   ```\n   source env/env.sh\n   ```\n   \n4. Compile the hw:\n   ```\n   make checkout\n   make build\n   ```\n\n5. Run the tests. Choose any test among the `parallel_bare_tests` and the\n   `mchan_tests`, move into the related folder and do:\n\n   ```\n   make clean all run\n   ```\n\n   To use the GUI, add `gui=1` to the previous command.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulp-platform%2Fpulp_cluster","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpulp-platform%2Fpulp_cluster","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulp-platform%2Fpulp_cluster/lists"}
