I am doing some stress testing on FIX message parsing on a GPU. What is a reasonable number of messages I should aim to parse per second?
thanks
FIXAntenna - the engine that I use - is advertised at 60k-115k messages/sec per instance.
It really depends entirely on your needs. If you are doing it for experimentation, then my answer is "as fast as possible, and even then, that's not fast enough".
If you are interfacing to the Namibian Stock Exchange, then a reasonable amount is 1000/day - there were 250 trades on the NSX last year.
I'm going to go the spectacularly unexciting route and say 1/sec.

I want to know what is the best WebHosting service that is cheap
If you are just starting out, I recommend Firebase Hosting (https://firebase.google.com/pricing).
This would suit you because it is free to get started. As long as it is only you and a few friends trying it out, you will find the cost is $0.
Only when thousands of people are using it, or you are storing hundreds of images or videos, will it start to cost something, and that cost is predictable.

I understand that Chisel is a HDL/HCL language to overcome some of Verilog/SystemVerilog restrictions by using higher abstraction level.
And it is open source as well.
It might be a bit naive and presumptuous, but still I would like to ask.
My question is that why do so many similar efforts are working in parallel, e.g. Blusspec, spinalHDL, Pyha etc?
I mean, is there any reason why the development community may not choose one of these and concentrate efforts on stabilizing or enhancing one of these.
That's exactly what is happening now, it just takes a while to choose.
Although the past does not show that the best technology wins, let us hope it does this time.

I was reading an article about facebook timeline https://www.facebook.com/note.php?note_id=10150468255628920
I always thought this kind of core produces would prefer Cassandra. However it is using MySQL/InnoDB.
Could anyone briefly explain why?
Available internal / external expertise with MySQL (it's easier to google solutions for existing problems)
Cassandra is much harder to reason about due to eventual consistency and limited transaction support
Moving to a new datastore is a lot of pain and it doesn't seem to be justified

I want to create a new rails application and I'm not sure whether to use MySQL or Postgres. Which one is best and what is the difference between them?
UPDATE:
The project is a health-care project. It may contain more than 500 tables.
postgres is secure, fast, and full of features but comparatively tricky to use.
MySql has its own benefits along with large user community and vast materials. Immensely helpful if you ever get stuck.
But ultimately it all comes to your preference and framework (apart from rails if your app requires any) support.

I was browsing through Mirosoft training website and found that they offer quite a bunch of online courses. Does anyone have any experience with these?
Having been forced to complete some of these dreadful E-learnings, I can tell you that they are boring. They do a very good job of blasting you in the face with all the theoretical knowledge, but they do a poor job of preparing you for the code you will see in the real world.
These are useful in discovering the way that someone in marketing in Microsoft imagines that their software / APIs will be used; they have little to no value in the real world.
