Tip Icom IC-V80

Entah kenapa LCD backlight atau layar LCD selalu menyala setiap kali HT dalam keadaan ON. Biasanya, latar LCD akan menyala jika ada perubahan setting. 5 detik kemudian layar LCD akan OFF. Setelah dicari-cari, ternyata setting LIGHT dari si HT tersebut dalam posisi ON, sehingga layar akan terus menyala selama transceiver (HT) sedang ON. Sebenernya ada 3 pilihan layar LCD :
  1. LIG.OF : Layar LCD akan terus OFF (mati) meskipun HT dalam keadaan ON
  2. LIG.ON : Layar LCD akan terus ON (hidup) selama HT dalam keadaan ON
  3. LIG.At : Layar LCD akan ON (hidup) jika ada tombol yang sedang ditekan. Layar akan OFF (mati) setelah 5 detik.
Cara settingnya : tekan [FUNC](*) lalu tekan [SET](8) lalu tekan Panah Atas atau Panah Bawah sampai ketemu tulisan LIG. Jika sudah ketemu, mainkan tombol [VOL] sehingga tampil tulisan LIG.At. Jika sudah selesai, tekan [VFO/MR/CALL].

Regional Workshop on Clustering for HPC

Hari Pertama :
Dr. Axel Kohlmeyer - Introduction to High-Performance Computing
Dr. Moreno Baricevic - Installation Procedurs for Clusters Part 1
Prof. Ivan Girotto - Compiling, lingking and running a "test case" code on a parallel linux environment for HPC
Hands-­on Lab Session 1 : as user, compile dan menjalankan "transport_serial.f90" dan "transport_parallel.f90"
File yang perlu di-download untuk hands-on session adalah Lab-Day1.tar.gz

Hands-­on Lab Session 5

The purpose of the exercise is to learn how to efficiently install scientific software for an HPC environment. The "case study" is the installation of the package Quantum ESPRESSO, one of the scientific application mainly used within the ICTP community. As many other, the code is characterized by the intensive use of math libraries for the solution to linear algebra problems and FFT. Particularly the exercise targets the installation of the pw.x binary. A sample input is provided.
To visualize the impact of an efficient installation you are request to perform two different steps: the common user way and the skilled way.

Hands-on Lab Session 1

The purpose of the exercise is to get feeling with a parallel environemnt for Cluster Linux systems. Learning how a such software environment works. It is propaedeutic to the next labs which have the goal to teach how to install and efficiently setup a similar system.

The main difficuties of the exercise is the implementation of the submission scripts for running serial and parallel codes on the Java2 Linux Cluster (Java2 is host name of LIPI's cluster). The script must be implemnted and submitted for execution through the resource manager how presented during class. See elcture's slide for syntax details. Running the different code version and analyzing the obtained data output you are expected to reckon the performance improvement abtained while running in parallel.
