Does Nvidia Use Perl?

It’s a common curiosity whether major tech companies like Nvidia use Perl as part of their software development or operations toolkit. Although Nvidia is primarily known for advanced graphics processing units (GPUs), AI hardware, and software like CUDA, like many large technology companies, they employ a wide range of programming languages for different purposes.

Perl's Role in Large Tech Companies

Perl has historically been a popular scripting language, especially in system administration, automation, build processes, and data manipulation. It excels in text processing, quick prototyping, and glue code tasks. Even if a company mainly develops software in languages like C++, Python, or CUDA, it is not uncommon to find Perl scripts in:

• Build and continuous integration systems
• Deployment scripts
• Log parsing and report generation
• Legacy automation tasks
• System or test automation

While Nvidia does not publicly document every language they use internally, evidence from job postings, open source projects, community forums, and older scripts strongly indicates that Perl is often part of their internal toolkit or infrastructure. This isn’t unique to Nvidia—many companies with long histories have Perl scripts running under the hood alongside their main software.

Why Perl?

Despite newer scripting languages like Python gaining popularity, Perl’s strengths include:

• Powerful regular expressions and text manipulation
• Concise code for complex tasks
• CPAN modules network (even core modules help a lot)
• “There's more than one way to do it” (TMTOWTDI)—giving flexibility

These features make Perl a natural choice for automation and scripting where reliability and speed of development matter.

Perl Example: Simple Nvidia Hardware Log Parser

Below is a small example to illustrate typical Perl usage. Suppose you have a log file from an Nvidia GPU testing system, and you want to parse lines containing temperature information and summarize them:

#!/usr/bin/perl
use strict;
use warnings;

# Sample log lines simulating Nvidia GPU temperature reports
my @log = (
  "GPU0: temp=65C power=150W",
  "GPU1: temp=70C power=160W",
  "GPU2: temp=60C power=145W",
  "GPU0: temp=67C power=155W",
);

my %temps_by_gpu;

foreach my $line (@log) {
    if ($line =~ /GPU(\d+): temp=(\d+)C/) {
        my ($gpu, $temp) = ($1, $2);
        push @{$temps_by_gpu{$gpu}}, $temp;
    }
}

foreach my $gpu (sort keys %temps_by_gpu) {
    my $temps = $temps_by_gpu{$gpu};
    my $count = scalar @$temps;
    my $sum = 0;
    $sum += $_ for @$temps;
    my $avg = $sum / $count;
    printf "GPU%s average temperature: %.1f°C (from %d samples)\n", $gpu, $avg, $count;
}

This script demonstrates some Perl essentials:

• @log: An array holds sample lines, simulating a GPU log.
• Regular expressions with capturing groups /GPU(\d+): temp=(\d+)C/ extract GPU identifiers and temperature readings.
• Data collection using a hash of array references %temps_by_gpu keyed by GPU number.
• Simple arithmetic and output formatting with printf.

You can run this script as-is via perl scriptname.pl (or copy-paste into perl - STDIN) and see the summarized GPU temperature averages.

Summary

• Does Nvidia use Perl? Almost certainly yes, at least for some internal scripting, build, testing, or automation tasks.
• Perl remains valuable for text processing, automation, and legacy systems in many tech companies.
• Its principle of TMTOWTDI ("There's more than one way to do it") allows developers to choose concise or explicit styles.
• Even if not directly related to Nvidia's GPU firmware or CUDA software, Perl is a useful tool in their broader engineering ecosystem.

If you are interested in using Perl for your own GPU data parsing or automation, the example above is a practical starting point illustrating core Perl capabilities like regexes, references, and formatted output.
