安装完yellow dog　6.2之后发现只有一些cell的编译工具，却没有发现需要使用的一些开发包，重新将安装盘mount作为repo。
[root@cell-node1 dev]# mount  /dev/cdrom /mnt/yd6cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@cell-node1 dev]# cd /mnt/yd6cdrom
[root@cell-node1 yd6cdrom]# ls
etc  eula.txt  images  LICENSE  ppc  PS3  RELEASE-NOTES  RELEASE-NOTES.en  repodata  RPM-GPG-KEY  TRANS.TBL  YellowDog

如果不加入MPI的通信函数，比如只有MPI_Init MPI_Finalize,或者一些本地操作，二者可以正确互联，但是如果加入mpi操作，则出现如下操作。
[node2][[44798,1],0][btl_tcp_endpoint.c:638:mca_btl_tcp_endpoint_complete_connect] connect() to 10.10.4.70 failed: No route to host (113) read more

Introduction
The PS3 is both a game console and a computer. Game consoles traditionally output to TV screens, computers traditionally output to computer monitors. TV screens and computer monitors have very little in common. The PS3 can output to both, and can also output to High-Definition (HD) TV screens. Since this involves several completely different sets of standards, things can get complex. This HOWTO will show you how to make your selected PS3 video mode permanent. read more

PS3  上 Linux  安装的默认显示配置取决于您的安装方法。如果您正在使用一个普通的 NTSC 或 PAL 电视机（而不是 HDTV 或连接到监视器的 VGA 转换器），就无法使用 YDL 的图形安装模式，因为它会试图设置一个更高的扫描分辨率。 read more

HowTo: Fullscreen on a 1080p HDTV

修改分辨率：
# vim /boot/etc/yaboot.conf
找到append="video=ps3fb:mode:5 rhgb quiet root=LABEL=/1"
修改mode后面的参数：比如上面的5，如果想全屏，需要再在这些id+128，比如5+128=133
Video mode ID:

CBLAS是BLAS的C语言接口。BLAS的全称是Basic Linear Algebra Subprograms，中文大概可以叫做基础线性代数子程序。主要是用于向量和矩阵计算的高性能数学库。本身BLAS是用Fortran写的，为了方便 C/C++程序的使用，就有了BLAS的C接口库CBLAS。BLAS的主页是http://www.netlib.org/blas/，CBLAS的下 载地址也可以在这个页面上找到。 read more

测试Open MPI的安装

命令"ompi_info"可用来检测Open MPI的安装状态。该命令会返回 一个关于你的Open MPI安装的大概信息。

Note that the ompi_info command is extremely helpful in determining which components are installed as well as listing all the run-time settable parameters that are available in each component (as well as their default values). read more

最近遇到一个超级难查的错误，一方面所因为程序所MPI并行程序，很难debug，基本没有啥可用的调试工具。其实之前用ubuntu编译完mpi程序后，执行即出现了错误，虽然没有解决，但我怀疑所环境问题。可能某些链接库的版本不对。
所以我用centos编译的open mpi是可以的，但是在将我的32位机与64位机并行时，在处理简单的程序时是没有问题的。
如下：
#include "mpi.h"
#include <stdio.h>
#include <math.h>
int main(int argc,char ** argv)
{
    int myid, numprocs;
    int  namelen;
    int type_size;
    char processor_name[MPI_MAX_PROCESSOR_NAME];
    MPI_Init(&argc,&argv);
    MPI_Comm_rank(MPI_COMM_WORLD,&myid);
    MPI_Comm_size(MPI_COMM_WORLD,&numprocs);
    MPI_Get_processor_name(processor_name,&namelen);
    fprintf(stderr,"Hello World! Process %d of %d on %s\n",myid, numprocs, processor_name); read more

在我的ubuntu上安装了openmpi,编译一个简单程序如下：
#include "mpi.h"
#include <stdio.h>
#include <math.h>
int main(int argc,char ** argv)
{
    int myid, numprocs;
    int  namelen;
    int type_size;
    char processor_name[MPI_MAX_PROCESSOR_NAME];
    MPI_Init(&argc,&argv);
    MPI_Comm_rank(MPI_COMM_WORLD,&myid);
    MPI_Comm_size(MPI_COMM_WORLD,&numprocs);
    MPI_Get_processor_name(processor_name,&namelen);
    fprintf(stderr,"Hello World! Process %d of %d on %s\n",myid, numprocs, processor_name); read more
