好久没有更新了,有点不太象话了.
编写helloworld.c
#include 'mpi.h'
#include <stdio.h>
int main(int argc, char *argv[])
{
MPI_Init(&argc,
&argv);
printf('Hello,
world!\n');
MPI_Finalize();
return 0;
}
~/service/mpi/bin/mpicc -o helloworld helloworld.c

public class AccessExample

1 下载jdk-1_2_2_017-linux-i586.tar.gz
2 解压缩到/usr/home/chunjian/service/jdk1.2.2
3 vi ~/.bash_profile添加
JAVA_HOME=/usr/home/chunjian/service/jdk1.2.2
JRE=$JAVA_HOME/jre
CLASSPATH=$JAVA_HOME/lib:$JRE/lib:.
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$JRE/bin:.
export JAVA_HOME JRE CLASSPATH
export PATH
4 重新登陆环境
5 编写HelloWorld.java
public class HelloWorld
{
public static void
main(String args[])
{
System.out.println('Hello World!');
}
}
6 javac HelloWorld.java
7 java HelloWorld
