Re^3: Using fork for reading and processing a large file in ActiveState perl

Dude, read the other posts before replying,

I did, no one mentioned to him how to bring in his huge file, and effectively split it, in order to hand them off to his threads for the parallel-processing. The OP asked I am reading and processing a huge file and recording results to another file which takes hundreds of hours. I want to run this task in multithreads..

How is it wrong to show how to get his input file split into bite sized chunks for his threads? I question whether you understand what needs to be done in an actual program. Maybe you didn't actually look at the link I provided? I showed him the various ways to achieve the first step needed for his code. See How to break up a long running process for some parallel processing usage.

I did Your reading skills are lacking. Here the OP says he needs to read a small file and write to a large file. The link you gave as well as the nonsense you posted ("threads don't help on a single-core processor, but multi-core machines magically reduce IO time") do not help with that problem.	[reply]

Yes, my apologies....I was having some stressful health problems. I read better now. :-) I'm not really a human, but I play one on earth. Old Perl Programmer Haiku	[reply]
