qtthread to speed up the algorithm

[leonardhead]

Hello,

I have a problem of parallel 3 different algorithm, I want to use the qthread to run this 3 algorithm at the same time.

if i run them in sequence, it will cost 12mins 12 mins and 17 mins which is 41 mins totally.

I tried the QThread to let them run at the same time, the cpu usage shows that they are running at the same time. However, it cost me 2 hours to finish the whole process.

I am just wondering is there anyway to run 3 different algorithm at the same time, and fast speed.


thank you

how many core have you computer?

each algorithm must run in one core to reduce the execution time. if only have one core the 3 algorihtm run at the same time using the processador, and when interchange the algorithm CPU cyles are used and take more time to run the 3 programs in batch mode.

sorry my poor english
