Thread vs Process

 https://www.guru99.com/difference-between-process-and-thread.html


Properties of Process

Here are the important properties of the process:

  • Creation of each process requires separate system calls for each process.
  • It is an isolated execution entity and does not share data and information.
  • Processes use the IPC(Inter-Process Communication) mechanism for communication that significantly increases the number of system calls.
  • Process management takes more system calls.
  • A process has its stack, heap memory with memory, and data map.

Properties of Thread

Here are important properties of Thread:

  • Single system call can create more than one thread
  • Threads share data and information.
  • Threads shares instruction, global, and heap regions. However, it has its register and stack.
  • Thread management consumes very few, or no system calls because of communication between threads that can be achieved using shared memory.

Amazon Linux 2023 - User data configuration for launch templates to connect to the EKS cluster

  Amazon Linux 2023 (AL2023) introduces a new node initialization process nodeadm that uses a YAML configuration schema. If you’re using self-managed node groups or an AMI with a launch template, you’ll now need to provide additional cluster metadata explicitly when creating a new node group MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="//" --// Content-Type: application/node.eks.aws --- apiVersion: node.eks.aws/v1alpha1 kind: NodeConfig spec: cluster: name: my-cluster-name-prd apiServerEndpoint: https://D59F.xyz.ap-northest-2.eks.amazonaws.com certificateAuthority: Y2VydGlmaWNhdGVBdXRob3JpdHk= cidr: 172.10.0.0/16 kubelet: config: clusterDNS: - 172.10.0.10 flags: - --node-labels=app=my-app,environment=production --// Content-Type: text/x-shellscript; charset="us-ascii" #!/bin/bash set -o errexit set -o pipefail set -o nounset # Install additional packages yum install -y htop jq iptables-services --//--

Fixing the DeepSpeed Import Error While Fine-Tuning the Qwen Model

While fine-tuning the Qwen model, I encountered an error in the finetune.py script: ImportError : cannot import name 'deepspeed' from 'transformers.deepspeed' After some investigation, I discovered the issue stems from a recent update in the Transformers library. The transformers.deepspeed module has been deprecated and replaced by transformers.integrations . To fix this, you need to update the import statement in your script. The Fix Replace this: from transformers.deepspeed import deepspeed With this: from transformers.integrations import deepspeed This small change resolved the error, allowing the fine-tuning process to proceed smoothly. Additional Resources For more details, refer to the discussion in the official Transformers GitHub repository: Issue #34582 Remember to keep your library versions up-to-date to avoid similar issues in the future!
