OpenTPU: An Open-Source Reimplementation of Google's TPU

UC Santa Barbara's ArchLab has released OpenTPU, an open-source re-implementation of Google's Tensor Processing Unit (TPU). Based on details from Google's research paper, but lacking a formal specification, OpenTPU differs in several implementation details from Google's design. Currently supporting matrix multiplication and ReLU/sigmoid activation functions, OpenTPU is missing features like convolution and pooling. Implemented using PyRTL, the project includes hardware and functional simulators, along with a checker for verifying results. While lacking hard synthesis figures for a full 256x256 OpenTPU at this alpha release, its open-source nature offers valuable learning and improvement opportunities for researchers.

Efficient Right-Truncatable Prime Counter in C

This C program efficiently calculates the number of right-truncatable primes for a given number of digits. It utilizes a custom hash table for fast primality checks and the primesieve library for optimized prime generation. A right-truncatable prime remains prime after successively removing its rightmost digit. The program handles input from 1 to 19 digits, reporting the count of right-truncatable primes for each digit length and the total execution time. For example, for 8-digit numbers, it finds 5 such primes and a total of 83 up to 8 digits.

Tenstorrent: Stop Stacking Abstractions, Focus on Core AI Compute

Tenstorrent: Stop Stacking Abstractions, Focus on Core AI Compute

This post sharply criticizes Tenstorrent's AI compute architecture, arguing its over-reliance on abstraction layers (LLK) leads to inefficiency and prevents it from competing with giants like Nvidia. The author advises Tenstorrent to focus on three core modules: frontend (PyTorch/ONNX, etc.), compiler (MLIR/LLVM, etc.), and runtime. The runtime should be hardware-agnostic, and the compiler should focus on memory placement, op scheduling, and kernel fusion, avoiding unnecessary activation functions like ELU. The author emphasizes that only by simplifying the architecture and improving the performance of core components can Tenstorrent succeed in the AI compute field.

Breaking Change: List API Filter Overhaul with Nested Expressions

Breaking Change: List API Filter Overhaul with Nested Expressions

The List API has undergone a significant update, now supporting nested and complex filter expressions. This is a breaking change requiring users to update their client libraries. All clients have been updated to support the new syntax and assist in constructing nested filters. For raw HTTP users, the filter format changed from col[ne]=val to filter[col][$ne]=val, following QS conventions. For example, excluding a value range [v_min, v_max]: ?filter[$or][0][col][$gt]=v_max&filter[$or][1][col][$lt]=v_min. A new Swift client implementation has been added. The release version is now shown in the admin dashboard with a link to the release page. Dependencies have also been updated.

Mysterious `runtabloid` Program: Huge Performance Discrepancy

The `runtabloid` program exhibits a striking performance difference when processing different programs. Running the `prog` program yields an almost instantaneous result of 110. However, running `fibo` and `fibo2` (both calculating Fibonacci numbers) takes a significantly longer time, 27.589 seconds and 56.749 seconds respectively. What is the secret behind this disparity? Is it algorithmic inefficiency, or are there differences in program design leading to such a massive performance gap? Further analysis of the code and execution flow might reveal the answer.
