 Posted: Wed Jul 27, 2005 6:27 am Post subject: 请问如何让openmosix运作 |
 |
|
请问有没有人可以分享以下他的openmosix in gentoo的经验呢？
我建立了两个node，可以互相找到对方，通过openmosixview 看到对方的cpu, memory load但是无法分布load和真正让openmosix有效。
详情请参考这个帖子:
https://forums.gentoo.org/viewtopic-p-2604522.html#2604522
主要是想弄懂如何在上面建立no password ssh,好像需要ssh来转移一些命令。
| Code: | * Openmosixview will allow you to monitor all nodes in your cluster.
*
* You will need ssh to all cluster-nodes without password.
*
* To setup your other nodes you will have to copy the
* openmosixprocs binary onto each node
* (scp /usr/local/bin/openmosixprocs your_node:/usr/local/bin/openmosixprocs)
*
* Start openmosixcollector
* manually (/etc/init.d/openmosixcollector start) or
* automatically using rc-update
* (rc-update add openmosixcollector default).
*
* Run openmosixview by simply typing openmosixview.
* |
哭阿，大哥们帮忙。
谢谢。

dundas，看來，還沒有人在這個openmosix下過苦功，我想你就是那拓路先鋒了。

但對於這個問題，我倒是可以說幾句。
sshd，除了可以用密碼來證証登入者之外，也可以用密碼匙，建立機器互信。 （我用它來建立遠程自動備份）(例子)
設定 OpenSSH
應該符合no password ssh的需求。
剩下如果有openmosix下的特殊設置，就要你自己摸。
祝好運。

ssh-keygen生成互信密码，几个机器共享一个非对称密匙，就可以免密码。
问题是，Distributed System之间没有1000M的带宽的话，瓶颈永远存在，反而会降低速度。另外还要有完善的算法。
MPICH不错。。。但是必须靠专门编程才能去完成一个任务。嘿嘿，Leduc的课我A－。 |

to akar:
actually I'm not alone on openmosix, MACHINE is also doing some test on mosix 2.6 kernel, we'll see.
to tiger:
yes, it's true we need 1G M switch.
I'll leave MPICH to software engineers.
Good , Leduc always loves you, haha.

now I got both
quantian (based on clusterknoppix) to PXE boot slave nodes
and
gentoo openmosix 2.4.30-r3
working and migrating processes
(only problem wiz the gentoo that it's actually not auto-balancing, either it put the load on the slave or put it on the master, so I still got problems here)
so akar, if u got friends knowing well about openmosix or other clustering like bewolf, ROCK or be or openBSD, I do appreciate if we can discuss something.
hehe, thanks
