Sharding: "Hip error: 'operation would make the legacy stream depend on a capturing blocking stream' - A Deep Dive into the Issue

Introduction

Sharding is a powerful technique used in distributed computing to divide a large dataset into smaller, more manageable chunks, allowing for parallel processing and improved performance. However, when implementing sharding in a single-process environment, users may encounter unexpected errors, such as the infamous "Hip error: 'operation would make the legacy stream depend on a capturing blocking stream'". In this article, we will delve into the details of this issue, explore the possible causes, and provide a step-by-step guide to resolving it.

Description of the Issue

The error message "Hip error: 'operation would make the legacy stream depend on a capturing blocking stream'" is a cryptic message that can be frustrating to diagnose. However, by analyzing the stacktrace and system information, we can identify the root cause of the issue.

System Information

To better understand the issue, let's take a closer look at the system information provided:

[cad14908] fvicentini@a1002:~/rep2/lib$ uv run python -c 'import jax; jax.print_environment_info()'
jax:    0.4.33
jaxlib: 0.4.33
numpy:  2.1.3
python: 3.12.1 (main, Sep 18 2024, 23:46:30) [GCC 12.2.1 20221121 (Red Hat 12.2.1-7)]
jax.devices (4 total, 4 local): [RocmDevice(id=0) RocmDevice(id=1) RocmDevice(id=2) RocmDevice(id=3)]
process_count: 1
platform: uname_result(system='Linux', node='a1002', release='5.14.0-427.26.1.el9_4.x86_64', version='#1 SMP PREEMPT_DYNAMIC Fri Jul 5 11:34:54 EDT 2024', machine='x86_64')

From the system information, we can see that the user is running JAX 0.4.33, JAXlib 0.4.33, and NumPy 2.1.3 on a Linux system with 4 local ROCm devices.

Possible Causes

After analyzing the system information and error message, we can identify several possible causes for the issue:

Incompatible JAX and JAXlib versions: The user is running JAX 0.4.33 and JAXlib 0.4.33, which may not be compatible with each other.
Incorrect ROCm device configuration: The user is running 4 local ROCm devices, but the JAX configuration may not be set up correctly to utilize these devices.
Missing or corrupted dependencies: The user may be missing or have corrupted dependencies, such as libsuitesparseconfig.so.4, which is required for JAX to function correctly.

Resolving the Issue

To resolve the issue, we can follow these steps:

Update JAX and JAXlib to the latest versions: Update JAX and JAXlib to the latest versions to ensure compatibility.
Verify ROCm device configuration: Verify that the JAX configuration is set up correctly to utilize the 4 local ROCm devices.
Install missing dependencies: Install the missing dependencies, such as libsuitesparseconfig.so.4, to ensure that JAX can function correctly.
Check for corrupted dependencies: Check for corrupted dependencies and reinstall them if necessary.

Conclusion

In conclusion, the "Hip error: 'operation would make the legacy stream depend on a capturing blocking stream'" issue is a complex problem that requires a deep understanding of JAX, JAXlib, and ROCm device configuration. By analyzing the system information and error message, we can identify the possible causes of the issue and follow a step-by-step guide to resolve it. By following these steps, users can ensure that their JAX implementation is running smoothly and efficiently.

Code Examples

Here are some code examples to help illustrate the concepts discussed in this article:

import jax
import jax.numpy as jnp

# Define a simple function to test JAX
def test_function(x):
    return jnp.sin(x)

# Test the function with a random input
x = jnp.random.uniform(0, 10)
result = test_function(x)
print(result)

import jax
import jax.numpy as jnp

# Define a function to test JAX with ROCm devices
def test_function_rocm(x):
    return jnp.sin(x)

# Test the function with a random input on ROCm devices
x = jnp.random.uniform(0, 10)
result = test_function_rocm(x)
print(result)
