if that were the case, the government would be to blame for the fact that so many companies were left vulnerable to Friday’s attacks. It takes time for companies to roll out systemwide patches, and by notifying Microsoft of the hole only after the N.S.A.’s hacking tool was stolen, activists say the government would have left many hospitals, businesses and governments susceptible.

“It would be deeply troubling if the N.S.A. knew about this vulnerability but failed to disclose it to Microsoft until after it was stolen,” Patrick Toomey, a lawyer at the American Civil Liberties Union, said on Friday. “These attacks underscore the fact that vulnerabilities will be exploited not just by our security agencies, but by hackers and criminals around the world.”

There has been some good news: an ingenious discovery appears to have halted the spread of the virus for now.

As part of the digital attack, the hackers included a way of disabling the malware in case they wanted to shut down their activities, Ars Technica reported. To do so, the assailants included code in the ransomware that would stop it from spreading if the virus sent an online request to a website created by the attackers. The kill switch would stop the malware from spreading as soon as the website went online and communicated with the spreading digital virus.

A British-based researcher, who declined to give his name, registered a domain that he noticed the malware was trying to connect to, limiting
the worm's spread. When the 22-year-old British researcher, whose Twitter handle is @MalwareTechBlog, confirmed his involvement but insisted on anonymity because he did not want the public scrutiny, saw that the kill switch’s domain name — a long and complicated set of letters — had yet to be registered, he bought it himself. By making the site go live, the researcher shut down the hacking attack before it could fully spread to the United States.

However, this temporary workaround will only last for a few days if not hours.

Italy hasn’t turned a blind eye to the problem and has a special unit devoted to food fraud. According to 60 Minutes, as of last year, that squad included 60 police capable of identifying fraudulent olive oil by taste tests and 1,100 officers who focus on inspection and investigation.

GPGPU stands for General-purpose computing on Graphics Processing Units
and to do any computing on DirectX 11 supported hardware we need to use
shaders. A shader is a program that is executed on the GPU. There are
di erent kinds of shaders, e.g. Compute Shader, Pixel Shader and Vertex
Shader. Of the ones in the Direct3D 11 interface the Compute Shader is the
only one focused upon GPGPU.

With cuda, you can write to arbitrary memory locations. With a shader, you're limited to writing to the pixel you're processing. That right there is probably the single biggest advantage of cuda. Yes, there are work-arounds with vertex/geometry shaders, but even in the best case, these will implicitly flush the instruction buffer, texture caches, require communication with the CPU, take a detour through triangle setup, ect. Can we say context switches? Thus, for scatter, it's clear that cuda is vastly more efficient.

Basically, the trade off is simple:
Cuda can do anything a shader can, and some things a shader can't, and almost always as fast or even a bit faster.
But cuda only works on Nvidia GPUs.

I would add that shared memory is the other big advantage of CUDA/OpenCL over pixel shaders. This can provide big performance improvements in bandwidth-limited image processing algorithms.

---

- Can set number of threads
- Can set number of blocks
- Can optimize using different memory spaces available
- Can customize thread load balancing to one's choosing

These are perhaps the most important points. There is a lot more transparency with CUDA. You know what magic numbers affect performance and you can tune your code appropriately to make sure you get the most out of the video card.
