AMD iGPUs Use 128GB Memory on Linux via GTT
Read Full Article: AMD iGPUs Use 128GB Memory on Linux via GTT
AMD's integrated GPUs (iGPUs) on Linux can leverage up to 128 GB of system memory as VRAM through a feature called Graphics Translation Table (GTT). This dynamic allocation allows developers to utilize iGPUs for tasks like kernel optimization without impacting the CPU's memory pool until needed. While iGPUs are slower for inference tasks, they offer a cost-effective solution for development and profiling, especially when used alongside a main GPU. This capability is particularly beneficial for those working on hybrid CPU/GPU architectures, enabling efficient memory management and development of large memory AMD GPU kernels. This matters because it opens up new possibilities for affordable and efficient computational development on standard hardware.

The concept of AlphaEvolve proposes a novel approach to algorithmic optimization by leveraging neural networks to learn a continuous space representing a combinatorial space of algorithms. This involves defining a learnable embedding space where algorithms are mapped using a BERT-like objective, allowing for functional closeness to correspond to Euclidean proximity. The method utilizes a learned mapping to represent performance, transforming algorithm invention into an optimization problem that seeks to maximize performance gains. By steering the activation of a code-generation model, theoretical vectors are decoded into executable code, potentially revolutionizing how algorithms are discovered and optimized. This matters because it could significantly enhance the efficiency and capability of algorithm development, leading to breakthroughs in computational tasks.
