了，并且已经分配IO了，这就是有些case not found的人，突然查到批准了。 |

发帖数: 7272 | 3 我觉得这个survey写的不是非常清楚。以下是我的comments。
Tony/Vivian,
I am not in Wooton Cluster. However, I've taken a little time to go over
the survey. Overall, it seems fine. However, there seem a couple of items
that can be improved.
2. How knowledgeable are you about Curriculum 2.0?Click all that apply
•know just a little
•know a fair amount
•know a lot
•somewhat of an expert, parents come to me with questions
Comment: Is it possible to change it to checkbox (multi choices)?

刚刚做的吊坠，手边的石头不多，捡了一些配起来比较和谐的，做了一个以前一直不敢
尝试的Cluster，上面的小宝石是烟晶，白水晶，紫水晶，绿水晶，黄水晶，粉玉髓，
青堇石，一颗小swa，下面是swa的D2U Heart。这个吊坠也算白搭吧，本来冷色调暖色
调都有，一年四季都可以戴了。 |

发帖数: 258 | 9 our group has a cluster named "Gladiator', it was built in 2002.
Gladiator is based on:
64 1.4GHz Athlon-MP CPUs, on 32 nodes
2GB DDR RAM per Node (64GB total)
Gigabit Ethernet interconnect
200GB of shared disk space
640GB of disk space distributed among nodes
The Linux SMP kernel
10 more nodes are being added into the farm now. |

发帖数: 1080 | 14 if i know the pair relations of a group of data, as a matrix, it looks like:
a b c d e
a 0.0 0.2 0.1 0.8 0.4
b 0.2 0.0 0.9 0.6 0.4
c 0.1 0.9 0.0 0.7 0.1
d 0.8 0.6 0.7 0.0 0.5
e 0.4 0.4 0.1 0.5 0.0
how can i cluster these data according their relations? is that possible? |

Cluster for a local network
P2P mainly on data sharing in a decentralized manner, can be a implementation
mechanism for Grid
WS a more popular standard like RPC, CORBA etc
Grid and WS are converging
Semantic Grid/WS is the future? Welcome bricks |

发帖数: 2 | 18 我看了半天, 怎么觉得cluster算法, 不管是K-NN还是SOM, 当然有其他的distance
measurement, 可是归根到底, 这些还是求欧几里德距离. 尤其是SOM, 我怎么觉得除了显

发帖数: 5958 | 32 Spectral clustering算法的瓶颈在于算NxN的相似性矩阵O(N^2)以及对其作特征值分解
。提高速度的关键就是对NxN的矩阵进行稀疏化。可以对每个点算其K-nearest
neighbor，然后矩阵只存K-NN对应的那些值，剩余的全都置0。 然后对稀疏矩阵用迭代
法进行特征值分解。对所有点在所有点上求K-NN (K-NN graph)可以用我在WWW'11上发
表的方法进行加速。 |

目前有哪些作者用了你的knn 算法作spectral clustering 啊？
速度以及内存消耗跟michael jordan 一伙人2009年提出的算法比较怎么样？ |

发帖数: 176 | 34 I don't think sparsigying the similarity matrix is a mainstream approach to
scale up spectral clustering. Low rank approximation like nystrom method
looks much more promising |

发帖数: 1511 | 35 My question is:
How many records do you have in the table?
If there are thousands of records, you need thousands of times of computing.
If there are millions of records, ...:( Database performance will be
horrible.
Probably better to process the calculation/clustering outside database.

发帖数: 14359 | 43 当然不行，何况CLUSTER是两个当一个用，必须是IDENTICAL的
你对2个当一个用并没有理解透彻，意思是2SERVER都是ON的，
但只有一个被APP使用，一但这个被用的DB SERVER有什么问题STOP了，
你会启动备用的SERVER，很显然这两个的配置和软件版本肯定是
要一致的，否则会有很多问题 |
