I repeat its only a sample code and needs to be tweaked a lot before actually using it but it doesn't mean that it won't work, it will work and as we are not aiming only at a just working code, always a better one
I have designed as a master-slave code.
Master code
Master will split the big file into chunks and the slave will process that. Finally master will delete the part files, other intermediate files and merge the final output.
Here is the master code
Slave code
For demonstration purpose, I have used a simple logic to split data of the form abcd;efgh
and form an output like abcd-efgh-efgh-abcd
Only the logic needs to be changed in the slave code and the master code is generic. It will work for all the cases and can be used for computations involving huge data where sequence is not important

Hi,
I have a large number of input files with two columns of numbers.
For example:
83 1453
99 3255

=83
1000<=<=2000
To do this I use the following... (10 Replies)
