Guide to Using the Center for High-Performance Computing (CHPC) at the University of Utah

This guide outlines the workflow for effectively utilizing the CHPC resources at the University of Utah. It covers setting up your environment, connecting to CHPC, managing interactive sessions, and tips for efficient computation.

1. Set Up Your CHPC Account

1.1. Set Bash as Your Default Shell

Usage Instructions for interactive() Bash Function

The interactive() bash function is designed to simplify the submission of interactive jobs using salloc. It provides default arguments for common resource requests and allows for customization through additional parameters.

Function Definition

interactive ()
{ 
    local DEFAULT_ARGS=(--account="$1" --partition="$2" --nodes=1 --ntasks-per-node=1 --cpus-per-task=4 --mem=64G --time="$3" --gres=gpu:l40s:1);

Optimizing Memory in Machine Learning: List vs Numpy Pre-allocation

In many machine learning applications, data handling is done using lists, which are then converted into numpy arrays. This practice can be memory inefficient, especially when dealing with large datasets. Below, I illustrate the problem and provide a solution using numpy pre-allocation.

The Problem

Let's take an example of data pre-processing with a list:

pre_processed = []
