As noted by AllThingsD, former Apple senior vice president of Mac Software
Engineering Bertrand Serlet has joined the board of directors at software
virtualization company Parallels. Serlet left Apple in March 2011 and was
revealed just weeks ago to be working on a new cloud-focused startup called
Upthere.
Serlet will serve as a non-executive director, bringing to Parallels his
distinctive professional experience of having led the development of Mac OS

in C++17
Oct 29, 2014
Although it is very early in the process, higher-level parallelism is slated
to be a key theme of the next version of C++, says Bjarne Stroustrup, the
founder of the language.
Interviewed recently, Stroustrup says the 35-year-old language has to
exploit new hardware, including transactional memory capabilities promoted
by IBM and Intel. To take advantage of these features, C++17 will need to

1、已经有parallels 8,里面装了windows7。再装boot camp是不是要先把parallel

2、每次click on setup.exe (for boot camp),总是跑到parallel windows里。这怎
么办? |

s******a 发帖数: 317 | 9 1. 速度没降下来, 是因为你的turn 没有完成,如果你能看到你的track的话,
complete and smooth turn 的 track 是比较圆的。 你现在的track应该有比较明显的
Z。另外注意一定要complete前几个turn, 否则你会越滑越快。
2. 正常,但是不能放任inner ski, 要actively 转转转它
3. carve turn 是parallel 的一种, 能carve了, 你的ski 肯定是parallel的。 反
之, parallel 不一定是carve, 有能是搓雪, skidded parallel. |

的道上拉绳子上去再滑下来,板子保持平行再扭扭屁股一点都不难,那也是parallel啊
我记得以前去过的一个雪场大概是这么定义滑雪者水平的
beginner skier, can link turns on easy terrain
intermidiate skier, can link turns on blue terrain
advanced skier, can link turns on black terrain
expert skier, can link turns on any terrain
关键不是parallel turn本身,关键是你能在多难的地形上link turns |

t******0 发帖数: 629 | 12 小弟目前处境:新手,感觉VLSI这一行的术语太多,有的时候大概明白点儿事儿了,却
不知道应该如何学术地表述。
我对parallel的理解,先不提流水线,就是把硬件功能模块增加,用面积来换吞吐量。
我对scalability的理解,就是按照这个设计思路,很容易把更多的硬件模块装进来,
然后吞吐率相同倍数的增加(如果throughput增加,却慢于面积的增加,就是不
scalable)
不知道以上理解对不对。
现在我想描述一个技术,但是不知道用什么术语来说:
比如输入是x1, x2,x3,x4.....xm (m个数),计算任务是先得出一个 m by m的方矩
阵,然后通过这个矩阵来算其他的东西,矩阵的元素是 f(xi,xj)。
所以总的计算量是m的平方(不考虑矩阵的对称性)。
我们可以用一个f(xi,xj)模块,进行2层循环,这样速度最慢,面积最小;
有的文章用 m 个改进的f模块,一次性地把 m 个输入量(x)都处理了,当然,这
种设计就是为了发论文,m 都不敢很大,而且硬件约束只能允许你处理 m 个数(这一
点还不如串行的设计呢)但是这种文章的关键词都是:paral... 阅读全帖 |

g**********8 发帖数: 273 | 14 我都要快考了,可是,教练还说我的pull over和parallel parking做的不是很好。说
我不用指望这些地方会有分数了。很沮丧。上来求教几件事情:
1.我想请教大家,考试的时候,对这些东东的要求真像教练说的那么严格吗?pull over
和parallel parking做完之后车身的距离必须与curb在6inch到12inch之间。比上述要
求近一点儿,也要扣分?但是,我看到手册上只要求了必须在12inch之内,太远不可以
,没有说比较近了会怎么样。不是吗?
目前这个距离有的时候比较难把握,大家如何去把握的?尤其是pull over和parallel
parking ? 当然重中之重是pull over.
2.回头check 盲点的时候,需要将身子都扭过去吗?我一直有check盲点的习惯,但是仅
限于扭头而已?!
3.另外,我要在renton考,不知道有什么需要注意的?
已经为了学车和考驾照花了n多的钱。希望大家帮帮忙。
多谢了。 |

o***d 发帖数: 7 | 15 这个冬天开始滑雪(Downhill SKI),大概滑了7,8次吧,绿道,蓝道都没什么问题,
比较Comfortable,黑道也可以下来,较紧张,自己觉得是用Parallel Turn 下来的,
现在有些困惑:
1.为什么即使不断地Turn,滑下来的速度也没觉得降很多?
2.每当转的时候,下山侧SKI的内边都Carve到雪里,而上山侧的SKI只是轻轻地浮在雪
面上,这是正常的Parallel Turn动作吗?
3.Carve Turn 和Parallel Turn 的区别到底在那里,是不是用那些Sidecuts比较深的
滑雪板自然而然地倾向于Carving Turn, 我用的是Rossignol Bandit B2。

(well, you can do some tricks on gpu and achieve somewhat parallelism,

parallel computing is for a multi-core cpu, or a cluster of cpus on either
one or many machines.
