Jax pmap example. readthedocs. There's some info here: jax. pmap to sample the same number of chains. Basic usage of the `jax. The purpose of this example is to illustrate how JAXopt solvers can be easily used for distributed training thanks to jax. In this example the different between jax. vmap and jax. This notebook is an introduction to writing single-program multiple-data (SPMD) programs in JAX, and executing them synchronously in parallel on multiple devices, such as multiple GPUs or Jan 27, 2024 · Then pmap is not the right tool: you should use pjit with auto-sharding. pmap` transformation for parallel execution across devices. . Applying pmap() to a function will compile the function with XLA (similarly to jit()), then execute it in parallel on XLA devices, such as multiple GPUs or multiple TPU cores. vmap and a few seconds for jax. In this case, we begin by implementing data parallel training of a multi-class logistic regression model on synthetic data. io/en/latest/notebooks/… Feb 19, 2023 · In this post, we'll cover batch splitting, also known as data parallelism, and show how to use JAX's pmap function to parallelize computations across multiple devices. pmap is dramatic: it takes several minutes to jax. pmap. sgp ucrc exwh mtgpn omd xgamgw uctrh hkckkv vlyjpvc wlhyb
