不知道厉害，然后就稍微减速过去了，我和车都差点没颠散架了。第二个我知道厉害了
，提前减速，竟然比第二次还颠，颠的时间还长。。。
我皮糙肉厚的，顶大就是颠傻点儿，可是我的车会不会被颠坏了呀？大家这种情况都怎
么处理？太快冲过去的话，会不会爆胎？
提前谢谢大家了！
BTW，骑回town的路上，看到了double rainbow；骑回家的路上，看到了昨晚失踪了的

但我觉得跟普通的foam roller也差别不大
gym有十几条呢，退了算了
还是进数据帝和大使推荐的cold roller吧
虽然贵点，但希望值回那50多刀的差价
这ITBS还是有明显感觉，心里急啊 |

发帖数: 3 | 20 Web service是现在企业架构中的一个方向。在我看来是替换RPC比较好的选择。Web
service有完善的发布方式(WSDL+UDDI)，SOAP协议(XML)提供安全的自解释的通讯方式。
但是UDDI Registry在安全性上还不足，所以web
service最好用于Intranet。J2EE和.Net都支持web service。可以到sun.com查询web
service的信息。
我觉得Grid Computing就是常说的Spatial Computing. 简单说就是GIS系统。由於文本数
据库管理系统已逐步向图像化地理化的管理系统过渡 - 80%的数据其实都是可以有几何信
息的。Computational Geometry是专门研究这些问题的。 |

发帖数: 985 | 21 事实上，WS已经发展到stateful的阶段了——WSRF
CORBA, technically and commercially, is dead.
WS最大的好处在于Interoperability.
我不认为messaging是少数。随着IBM的WS-Notification和MS的WS-Eventing
的进一步统一。基于WS的messaging/pubsub system将不断涌现。
messaging最大的好处在于asynchrony。大的job不会像zaiRPC里面一样被block乐。
the bottom line is, WS creates a higher level abstration of networks.
最典型的比如WS-reliable messaging就像TCP/IP一样。
since the beginning of 2004, Grid computing became a subset of Web services
(computing), with its own set of definitions -- OGSA. |

发帖数: 1269 | 22 What kind of major research directions in grid computing and
web services? Thanks! |
|
r*****s
发帖数: 985 | 23 not sure which version of Globus are you talking about, GT2?
GT3 and 4 are totally Web services.
GT3 = Web services + OGSI(OGSA)
GT4 = Web services + WSRF(OGSA)
BTW, Globus is not grid. it is a set of toolkits. There are many different
implementations, as long as it follows OGSA.
Sometimes, if you can coordinate everybody to use one standard, you are
the hero. Not every best solution is adopted. Fights between big companies
really hurt technologies. |

发帖数: 4965 | 24 这个所谓Grid 概念反映了Ian Foster 象商人一样的作法,
本来distributed computing ( not counting theoretical research )的目的
就是把各种resources 连起来以能easy access, 或者说这行业的人
一直都在做这个, 譬如condor 做的就是,
打个比方, 大家都会吃苹果,也从小到大都在吃苹果,
现在有张三突然说 "我提出一个吃苹果的framework, 这是一个open
standard, 你要先拿起来,然后看准,然后咬..... "
你不觉得很可笑么?
再说这个open 的概念吧, 任何东西没有写完都可以说是open,
你照样可以写些小程序在condor 的framework下面work,
也可以叫做extentions to that open framework ......
再看globus 2 到3的彻头彻尾的变化, 只有concept 上的继承,
或者说open 的只是concept/architecture, |

Any good one on analytical models? Typical papers on Grid are as follows:
1. a framework, preliminary implementation, some application experiments, show
several tables and figures, then give some intuitive thinking
2. an algo, with complex and fancy flowchart, some experiments, a little bit
on why and how
Any papers show the upper bound on the performance limit, speedup/efficiency,
analytical models, stochastic analysis etc. I noticed one stochastic p |

发帖数: 133 | 38 Cloud computing = grid computing, except cloud usually within same data
center
pervasive computing = ubiquitous computing
The first two is for desktop/PC, the other two is for mobile/embedded
In first two computing is somewhere far far away and you can't see them
In the other two computing is all around you and you stopped paying
attention to them |
