妈妈查出双颈动脉硬化,并左颈有斑块。但是医生不建议手术,因为斑块还不是特别大
。(妈妈还有心脏病,最近因为供血不足还有些心绞痛)
最近头疼的厉害,左侧肢体麻木,想请问问大家谁知道北京那个医院的哪个专家治疗这
个病最好。中医好还是去看西医好?
我个人看了一下大概有阜外,301,还有天坛医院都评价比较不错。
回答好的热包子伺候啊。10个。

关于举报J吃肉事件的分析
事件背景:
1.我一直对J吃肉这种行为有很多狐疑,因为观音法门对素食是非常严格的,包括waichi也是,那为什么J吃肉这种行为竟然一直能以一种合理的方式存在。究竟是J自己特殊,还是有其他原因?
2.我认为J吃肉这种行为,包括在bbs谈论这些有一种非常不好的示范作用:它所表示的信息是,“吃肉也不妨碍开悟”。素食并不是影响开悟明心的因素。这种示范作用也许不是刻意造成的,但确实存在。
3.我一方面同意理解J关于吃肉的观点,因为我其实和J在这方面很类似。另外一方面我也认为那种吃肉行为是给自己找借口。我也是矛盾的。我承认,我确实明显受到了J理论和吃肉这件事的影响。我在这方面也很糟糕和不堪。
4.waichi在版上说“吃肉没什么大不了的”,并直接说了吃肉也可以解脱,当然我知道他的那意思,听起来也很合理,但我也很狐疑公开发表这种言论是否恰当。因为这太容易被误解
5.我一直怀疑waichi有拉虎皮扯大旗的嫌疑(因为曾经有佛教高人警告过我),waichi和我是认识的观音法门弟子风格很不同,他所教我的根法也和清海的观光法门不同。

Hi,
I am trying to do parallelization for a computing intensive problem.
I am working on a Linux cluster where each node is a multicore processor.
e.g. 2 or 4 quad-core processor per node.
I want to reduce latency and improve performance as much as possible.
I plan to use multiprocessing and multithreading at the same.
Each process run on a distinct node and each process spawn many threads
on each node. This is a 2 level parallelism.
For multiprocessing, I would like to choose MPI.
For multithreading, I have two choices: openMP or boost::thread (pthread).
Which one has lower latency and higher performance ?
It seems that openMP coding is easier (without touching low level thread
managing manually).
But, it seems that openMP has higher overhead than boost::thread (pthread).
Any help is really appreciated.
thanks

It depends where your mother is, in northern china, 阜外 is roughly the best
in China. in shanghai or nearby, Zhongshan or ruijin is the best, in
southern china, Guangdong People's hospital is the best.
301 is good.
tiantan is not well know for issue of heart disease. Neurosurgery is one of
the best.
There is strict indication for the treatment of carotid atheroslcerosis.
<60 without symptoms, treat it medically, diet, reduce the risk factors.
60-99% surgically
100% no surgery.

严重自欺得太可怜了.
严重自欺及心性本污与创作的典范.

waichi也是,那为什么J吃肉这种行为竟然一直能以一种合理的方式存在。究竟是J自己
特殊,还是有其他原因?
的信息是,“吃肉也不妨碍开悟”。素食并不是影响开悟明心的因素。这种示范作用也
许\\不是刻意造成的,但确实存在。
我也认为那种吃肉行为是给自己找借口。我也是矛盾的。我承认,我确实明显受到了J
理论和吃肉这件事的影响。我在这方面也很糟糕和不堪。
道他的那意思,听起来也很合理,但我也很狐疑公开发表这种言论是否恰当。因为这太
容易被误解
waichi和我是认识的观音法门弟子风格很不同,他所教我的根法也和清海的观光法门不
同。
J吃肉的行为到底是否观音法门所原谅和允许\\,waichi是否和清海一致,于是我作出了
举报J的决定,并且公开了自己的决定。我当时真正的动机是求证,求证观音法门和清
海对此会如何看,会如何处理。
人骂的事情,举报这种行为有点像打小报告,像害人,是小人干的事情。但是我检查自
己的动机, 我认为我没有任何要去害J的动机存在,因为我当时和J根本就没什么矛盾
,甚至仅次于对waichii的尊敬,我不存在任何害他的

My guess is that Boost.Thread is faster. It has been added to the new C++
standard.

Are there other reasons ? Just because it will be in new standard ?

我个人比较喜欢OpenMP。 不需要加很多code,最简单的就只需要加一行, compiler就
可以自动把for loop平行。 线程的数目自动和你的CPU核的数目一致,每个核执行for
loop的不同index。 这些全都是自动的,不需要你操心。 你可以做data parallelism
和task parallelism.

OMP比thread抽象层次高,能有就用。
如果用pthread,你就得自己控制有多少个threads.
而且OMP提供许多collective操作,比pthreads好用多了
