发帖数: 1554 | 2 好像在C程序下要含有这个文件才能被R调用，但visual C++好像没有：
#include "stdafx.h"
#include "R.h"
using namespace System;
int main(array ^args)
{
Console::WriteLine(L"Hello World");
return 0;
}
这个程序编译时说
Cannot open include file: 'R.h': No such file or directory
请问应该怎么做？
比如我有一个程序useC.c
#include
/* useC.c */
void useC(int *i) {
i[0] = 11;
}
但在windows系统，命令行好像跟其它不大一样，用
R CMD SHLIB useC.c
显示“R不是内部或外部命令....”，请大家指点一下应该怎么做，谢谢。
在R下面用system("R CMD SHLIB useC.c")它说

In the past, multicore programming focuses on fully utilizing CPU. This can
be seen in the High-Performance Computing (HPC) benchmark rankings.
This approach neglects an issue that is ubiquitous: Most "processes" (
including computations, communications, and I/O) do not generate (yield) a
block of "result" of size N at once. Instead, almost all real-world
processes yield results incrementally.
To visualize, one can imagine this at a microscopic timing level:
After spending 500 microseconds of i... 阅读全帖 |

发帖数: 42 | 25 感谢版主组织SOAP讲座。感谢 TJ Xing前辈给我们分享经验。
SOAP？
2016 51% img match 在纽约
对于外国毕业生来说评分系统里step 1 &step2 分数是最重要的。签证政策改变对有绿
卡公民身份的同学是有优势的。
Soap主要为美国学生设立但是也有img 成功。
如何查看项目是否有soap名额？ 看往年nrmp match outcome项目是否招满，如有
unfilled position基本都有soap机会。
所有有资格的同学都会收到soap 邮件，与你是否match成功无关。
教训：不能只看内科或者病理，其他的科目也可以试试申请。当然ps 和推荐信要与专
科相关。Ps 对soap比较重要。
3/12 match results。 R3 12点左右开始， 大家可以看到所有项目的soap位置。大约
有150 (以前，今年只有45个名额)名额可以申请。总共有三轮。不要一次申满150个名
额。要看有内部关系的项目，尽量发动connection，如果项目能看到你的简历，很快就
能面试。内部推荐往往是优先的。首先要决定专业；其次看有联系的项目。往年有中国
