Multiple thread pool
-
hai, i am working in IOCP Socket programming..in this i want to craete multiple thread pools, which means 5 thread pools and each contains 100 threads... like this...how to create this,,, If u Knows,reply me... Mani

You mean you want to have 500 threads for your application ? Wow, that's a lot ! You'll probably spend more time switching between the different threads than doing usefull stuff. Why do you need so much threads ?

What does it have to do with a thread pool ?

Charting control [v1.2]hai, thanx for ur reply,actually the main task is banking transactions..so none of the request should not get failed... thats why my requirement is 500 threads...is there any problem,...? to handle this...

Why do you need one thread per request ? You could simply have one thread to queue the requests and one thread (or more) to process them.

Charting control [v1.2]i am having 100 threads in my server IOCP.. and it is listening for incoming connections.ok.. in client side i am using 500 threads, to send connection request to the server..! why 500 threads i am using is, 500 simultanous user trying to access server at a time.... now only 400 client requests are processed(accepted)...remaining 100 error ocurred... what to do for this..?

Try using Overlapped IO. In most cases it has proven to be more scalable than hand built threading schemes. Based on the description you provided it will likely be an improvement. What bank is this for? I want to make sure an never use it.

How many processors does your server have? 500 threads is a huge waste of resources on a machine with say, 4 processors. See Tip #2 here: INFO: Design Issues When Using IOCP in a Winsock Server[^] You should be able to handle thousands of connections with at most, a couple threads per CPU. Regardless, IOCPs don't have multiple thread pools. The thread pool size is determined by how many threads you have waiting on GetQueuedCompletionStatus(). Mark

The idea of using an IOCP is to eliminate the need to have a thread for every connection. The server is only capable of simultaneously running one thread per processor, so any more threads than that is a waste of memory, handles, and other system resources.
