Blocking and Non-blocking Communication in MPI

Blocking and Non-blocking Communication in MPI

Comments 216 Comments

In parallel computing with MPI (Message Passing Interface), communication between processes plays a crucial role in achieving efficient parallelization of algorithms. Two common approaches to communication are blocking and non-blocking communication. You can visit the detailed tutorial on MPI with Python here. Blocking Communication Blocking communication involves processes halting their execution until the communication operation is complete. In MPI, blocking communication functions like comm.send() and comm.recv() ensure that the sender waits until the receiver receives the message, and vice versa….

Introduction to Machine Learning

Introduction to Machine Learning

Comments 205 Comments

Machine Learning (ML) is a subfield of artificial intelligence (AI) that focuses on the development of algorithms and models that allow computers to learn from data and make predictions or decisions without being explicitly programmed for every task. The primary goal of machine learning is to develop algorithms that can learn patterns and relationships from data and use this knowledge to make predictions or decisions on new, unseen data. Imagine a dataset containing information about students’ attendance records, study hours…
