I'd go with first one.
Starting from a algo trading / automated execution developer, you can gain
exposure to theory and practice of market microstructure. This can serve you
well if you want to go to algo trading later, in any asset class.
Second job seems more like back office IT. In case you want to keep working
on IT and become project manager. Or, you can gain experience in handling
data and later become data manager, and work in finance or non-finance
companies.

来自主题: Quant版 - 为什么中国人做Trader的少?
when we talk about trader, does it usually mean sell-side non-algo trader?
Buyside/execution trader is a less prestige and less common role. And I'm
sure there are good number of Chinese algo traders in the industry.
It is not about "自卑"...Why do people feel "自卑" when their foreign
language skills are not good enough compare with native speakers?

[金工金数] 说说自己对Quant的理解---完整
写点自己对quant的理解,仅供参考
几句话写在前面
The largest casino is the Wall Street.
一下只是自己亲身感受和接触的观点,一家之言,难免片面不客观。
钱固然重要,但是除了钱还是有很多值得每个人追求的。并不是做金融就一定要唯利是
图。
主流 VS 非主流
个人认为国内对quant的主流认识还是为trading desk服务,或者是设计一些复杂的金
融产品。这种观点在国外也是偏向于主流的。我认识一些quant拿到了PHD之后就在GS,
UBS这些公司做起了risk quant或者为前台计算设计一些模型。这类型的quant在业界还
是占了很大很大的一部分,而这样的quant也是MFE的项目所培养的。也许你MFE或者PHD
毕业了以后,就要在相当一段时间帮前台计算P/L 或者VaR之类的。
前一阵和一个在trading desk工作的同学聊天,那种quant的不屑是很清楚的写在脸上
。的确,不可否认的是,主流认识的quant在创新和自主上还是有一些不足的。我想,
国内的券商,投行其实更多的是需要这样... 阅读全帖

If the lengths are unknown then:
1. assuming iteration allowed:
bi-section method. Half it to two numbers that can lead to the average num.
The sum you get from each run, is one of the (or two) numbers you obtained
from last cut. So the more you are left off with from each cut, the worse
the algo is.
e.g. 10 into 5 numbers
10 = 4 + 6 (cost 10) = 2 + 2 + 2 + 4 (cost 10) = 2 + 2 + 2 + 2 + 2 (cost 4)
in fact this algo leaves with a cost of target*num iteration + last split (2

是proba,stats,algo, finance一门数道题,看综合起来总分如何,lz看来finance

来自主题: Military版 - 太湖之光的CPU
太湖之光的CPU sw26010在设计取向上是针对“暴力浮点”优化的,出现上面这个结果
(FLOPS强,某些其他测试不太好)意料之中。
比较显著的一个指标是这个CPU的内存带宽/浮点比率达到令人难以置信的1/22.4=0.
045 Byte/FLOP。作为对比(数据来源Yokota,J Algo Comp Tech, 7,3,2013):
INTEL Xeon E5 2690: 0.211

NVIDIA Fermi GF110: 0.266
IBM PowerPC A2(BG/Q):0.208
Fujitsu Sparc64(FX10):0.359
相比较而言sw26010的内存带宽太小,很多操作都会卡在内存上。实际应用上,优化好
的FMM或者DGEMM大概需要0.2,使用特殊向量指令还可以更低,3D FFT大概需要0.6~0.

几个语言都够了。
python慢,一秒刷新一次还是够的。现在的Algo trading(real time),有些客户端
实现算法部分也是可以用java。一般的app,根本不用考虑这些东西。
http://www.exegy.com/wp-content/uploads/Exegy-Client-API_XTP-0034.pdf
网络延时,主要还是看你的server和客户的是否很远。做trading的都是把server放在
离交易中心很近的的地方。
你如果传输的东西很大,tcp/ip打碎成很多packets,来来回回还要验证是否出错或丢
包要重来,自然很慢。你每秒要传输100M的东西给客户端,用什么语言都不行。
当然,一般情况,也看你的客户量多大,太大超过负载你没法及时响应,客户端也会觉
得慢。
