I started to develope SPVM::Mojolicious

Yuki Kimoto — Sat, 09 Aug 2025 00:50:27 +0000

I started to develope SPVM::Mojolicious.

I released SPVM::Mojolicious on CPAN.

This is an early release.This project is incomplete.

We plan to make most Mojolicious features available.

As SPVM features, we'll be able to create groutines, threads, and executables.

How to create Mac GUI applications in SPVM?

How to create Mac GUI applications in SPVM?

See the following content.

Mac GUI Applications

SPVM can now create a Mac GUI application. It is an executable file. you can execute it.

% spvmcc -o mac_hello_world mac_hello_world.spvm
% ./mac_hello_world

An alert dialog is shown.

How to create a parallel echo server using goroutines in SPVM?

How to create a parallel echo server using goroutines in SPVM?

I write a parallel echo server using SPVM::IO::Socket::IP and goroutines, channels, select in SPVM::Go.

How to generate an executable file for an AI program using SPVM ?

Yuki Kimoto — Tue, 08 Oct 2024 04:59:31 +0000

Wouldn't you like to output a single executable file from your AI program? Then, you can run the AI program just by copying the executable file to the Raspberry Pi. Here's how to achieve this using SPVM. Here's an example of image recognition using MINIST as an example of AI using deep learning.

SPVM program

This is an AI program to recognize images using MINIST data.

It is writen by SPVM and SPVM::R.

Install dependent modules.

cpanm SPVM
cpanm SPVM::Errno
cpanm SPVM::File::Basename
cpanm SPVM::File::Spec
cpanm SPVM::FindBin
cpanm SPVM::Math
cpanm SPVM::Regex
cpanm SPVM::Sys
cpanm SPVM::Time::Local
cpanm SPVM::Time::Piece
cpanm SPVM::IO
cpanm SPVM::R

Execute an SPVM program.

spvm -I network_lib/SPVM my_minist_app.spvm

Generate an executable file and execute it.

spvmcc -I network_lib/SPVM -o my_minist_app my_minist_app.spvm

./my_minist_app

I'm not an AI expert, but if you are, I think you can modify this.

Yuki Kimoto — Wed, 21 Aug 2024 00:15:36 +0000

R class in SPVM is a port of the R language features.

Features

N-dimensional arrays and their operations, such as addition, subtraction, multiplication, division, modulo(or remainder), sum, max, min, mean, cumulative sum, cumulative product, trigonometric functions, exponential functions, log functions.
Support of sequence creation, repetition, slice, order, sort of a n-dimensional array.
Various types of n-dimensional arrays(byte, short, int, long, float, double, float complex, double complex, string, variable-length string, datetime).
Support of NA representation.
Data frame and its operations.
Support of slice(subset), order, sort of a data frame.

How to use OpenMP from Perl with SPVM.

Yuki Kimoto — Thu, 28 Mar 2024 00:10:25 +0000

How to use OpenMP from Perl with SPVM.

See an example to bind OpenMP to SPVM

SPVM provides a way to bind C language libraries and call them from Perl.

When binding C libraries to Perl, you typically write XS, but SPVM offers an alternative approach.

MyOpenMP.spvm

class MyOpenMP {

  native static method sum_vec_int : int[] ($nums1 : int[], $nums2 : int[]);

  static method test : void () {
    my $nums1 = [1, 2, 3];
    my $nums2 = [5, 6, 7];

    my $nums3 = &sum_vec_int($nums1, $nums2);

    for (my $i = 0; $i < @$nums3; $i++) {
      say $nums3->[$i];
    }
  }
}

MyOpenMP.c

#include "spvm_native.h"

#include <string.h>

static const char* FILE_NAME = "SPVM/MyOpenMP.c";

int32_t SPVM__MyOpenMP__sum_vec_int(SPVM_ENV* env, SPVM_VALUE* stack) {

  void* obj_nums1 = stack[0].oval;
  if (obj_nums1 == NULL) {
    return env->die(env, stack, "$nums1 must be defined.", __func__, FILE_NAME, __LINE__);
  }
  int32_t* nums1 = env->get_elems_int(env, stack, obj_nums1);

  void* obj_nums2 = stack[1].oval;
  if(obj_nums2 == NULL) {
    return env->die(env, stack, "$nums2 must be defined.", __func__, FILE_NAME, __LINE__);
  }
  int32_t* nums2 = env->get_elems_int(env, stack, obj_nums2);

  int32_t length = env->length(env, stack, obj_nums1);

  void* obj_nums3 = env->new_int_array(env, stack, length);
  int32_t* nums3 = env->get_elems_int(env, stack, obj_nums3);

  int32_t i;
#pragma omp parallel for
  for (i = 0; i < length; i++) {
    nums3[i] = nums1[i] + nums2[i];
  }

  stack[0].oval = obj_nums3;

  return 0;
}

MyOpenMP.config

use strict;
use warnings;

use SPVM::Builder::Config;

my $config = SPVM::Builder::Config->new_gnu99(file => __FILE__);

# Compiler options
$config->add_ccflag('-fopenmp');

# Linker option
$config->add_ldflag('-fopenmp');
$config->add_lib('gomp');

$config;

openmp.pl

use strict;
use warnings;

use FindBin;
use lib "$FindBin::Bin/lib";

use SPVM 'MyOpenMP';

SPVM::MyOpenMP->test;

This program outputs values calculated by OpenMP.
