Untuk memproses 2000-an record terhadap 2 juta record jika dijalankan dengan satu proses akan memakan waktu cukup lama karena karakternya yang serial. Untuk menjalankan proses yang parallel secara bersama maka kita dapat menjalankan lebih dari satu matlab dalam satu computer. Biasanya ini dilakukan jika kita ingin memproses data berukuran besar (big data).

First, you have to change current directory of your first matlab. If we want to create with two machines, you can open your Matlab again form start menu or from your shortcut wall. For example I want to use three Matlab for computing my algorithm at the same time for faster result.

Second, things that we have to consider is the location of the result, if you have the similar name to the output, you have to separate current directory because of the conflict of output (the last output will replace the previous one).

Last, you have to count the power of your machine. I use i5 processor, and sometimes I use four processing. The picture below show my Matlab that process 3 text processing of 2 thousand of author to other 2 million author.
