Write gigantic output files in parloop

Dear All,

I am running a program using parallel toolbox. Each identifier in the parfor loop creates a matrix of 2,000,000 * 10 which of elements are 10 digit numbers. I am currently using dlmwrite to save and export the matrix output. It takes the code a way way long time to write one output file.

Previously, I was dealing with smaller output and the code worked perfectly but now it is really time consuming and expensive. Is there any efficient way to save the outputs (not in binary format)?

Thank you so much

How long does the export take? On my laptop it's 90s and produces a 250 MByte file. As I see it, if you need to have it in ascii format, it will be difficult to get this much faster. Binary output of course is a different question, this would take a fraction of that time ...

A (maybe trivial) comment: don't write the output to some (slow) network drive but to a local hard disk. Copy later to the network drive if needed ...
