Petunjuk Penggunaan

pembuat : Rifki Sadikin (rifki.sadikin@lipi.go.id)
tanggal : 6 November 2018

Petunjuk penggunaan ini berisi:

  • Cara membuat dan menginstal Pustaka Pemercepat Komputasi berbasis GPU CUDA untuk Penyelesaian Persamaan Poisson dalam Koordinat Silindrikal.
  • Cara memakai Pustaka Pemercepat Komputasi berbasis GPU CUDA untuk Penyelesaian Persamaan Poisson dalam Koordinat Silindrikal dalam C++.

Struktur Berkas

Struktur berkas pustaka Pemercepat Komputasi berbasis GPU CUDA untuk Penyelesaian Persamaan Poisson dalam Koordinat Silindrikal adalah sebagai berikut:

|-- CMakeLists.txt
|-- docs
|   `-- Doxyfile.in
|-- example
|   |-- CMakeLists.txt
|   |-- PoissonSolver3DGPUTest.cpp
|   `-- PoissonSolver3DGPUTest.h
|-- interface
|   |-- PoissonSolver3DCylindricalGPU.cxx
|   `-- PoissonSolver3DCylindricalGPU.h
|-- kernel
|   |-- PoissonSolver3DGPU.cu
|   `-- PoissonSolver3DGPU.h
|-- PETUNJUKPENGGUNAAN.md
`-- README.md

Modul Program yang Dibutuhkan

Untuk menginstall pustaka dibutuhkan program pengembang di lingkungan sistem operasi Linux (saat ini masih di Linux) yaitu:

  1. CMAKE versi minimal 3.10.3
  2. GCC versi minimal 6.2.0
  3. CUDA versi minimal 8.0
  4. GIT versi minimal 1.8.3.1

Jika disediakan module program pada lingkungan sistem HPC maka dapat menjalankan perintah berikut ini:

module load cmake/3.10.3
module load gcc/6.2.0
module load cuda

Instalasi

Untuk menginstall pustaka PoissonSolver3D lakukan langkah-langkah berikut:

  1. Jalankan git clone untuk menyalin kode sumber ke direktori local. Perintah ini akan menyalin kode sumber ke direktori PoissonSolver3D
$ git clone http://github.com/rsadikin/PoissonSolver3D.git
  1. Pindah ke direktori PoissonSolver3D, dan lihat daftar direktori
$ cd PoissonSolver3D
$ tree .

  1. Buatlah folder buildpoissonsolver di luar direktori kode sumber
$ mkdir $HOME/buildpoissonsolver
  1. Pindah ke folder buildpoissonsolver
$ cd $HOME/buildpoissonsolver
  1. Jalankan cmake di folder buildpoissonsolver dengan menyatakan di mana pustaka akan diinstal dengan perintah sebagai berikut
$ export  PSLIB=/home/usertest/trypoissonsolver/PoissonSolver3D
$ export PSLIB_INSTALL=/home/usertest/buildpoissonsolver
$ cmake $PSLIB/ -DCMAKE_INSTALL_PREFIX=$PSLIB_INSTALL
