Running jobs on the Cerebras Wafer-Scale cluster is straightforward and similar to running them on a single device. Here’s a comprehensive guide to get you started.

Launch Your Job

 Cerebras Cluster Settings 

To optimize model performance on Cerebras hardware, we use a mix of pre-written and AutoGen (automatically generated) kernels.

Kernel Autogeneration with Autogen

In a Wafer-Scale Cluster execution, the input pipeline runs on input worker nodes within the cluster, which are separate processes started by the Appliance on different CPU nodes.

Define Environment Variables For Input Workers

If you are developing your own data loader, you might need to provide specific dependency packages in the virtual Python environments to support your data loader functions.

Import User Dependencies In Cerebras

ML Training is often bottenecked at the dataloader stage.

Troubleshooting

You trained a model using Cerebras cluster and you would like to reload the model for continued gpu training/inference. 

Cannot Load Cerebras Checkpoints In Gpus

Custom Pt Training Script Spawns Multiple Compile Jobs

 Loss Compilation Issues With Autogen 

 Error Parsing Metadata 

 Error Receiving Activation 

Failed Mount Directory During Execution

When adding a custom checkpoint into `model_dir`, the run command does not automatically pick that up in my model_dir and runs with it. Instead, it reports that no checkpoint is found.

 Failing To Automatically Load Checkpoints 

Failure To Trace Due To Functionalization Error

 Input Starvation 

The Cerebras Wafer-Scale Cluster explicitly enforces limits on Memory and CPU requests to enable parallel compiles and trains. This limits can be overridden depending on the user needs. You can learn more in resource_parallel_compile.

 Out Of Memory Errors And System Resources 

Model Is Too Large To Fit In Memory

 Modulenotfounderror 

 Numerical Issues 

If you notice a throughput spike after saving checkpoints, this is a known artifact of reporting throughput on the user node, caused by the asynchronous nature of execution on Wafer-Scale Cluster. For more details and understanding of this behavior, please refer to [Measure throughput of your model](/fundamentals/measure-throughput-of-your-model).
