I'm attempting to import a ~200 MB ascii text file of data that is formatted as a column of integers, like
==================
654654
1698184
654941
549879
564974
.
.
.
6466848
779821
==================
and so on, without the "====" appearing in the file.
I'm trying to import the data so I can run some calculations on it, using the command
dataset=Import["filename.txt","List"];
Importing this file causes the memory used by the kernel to balloon up to 800 megs of physical ram (as windows reports it), then it invades the system ram, and eventually returns the message:
No more memory available.
Mathematica kernel has shut down.
Try quitting other applications and then retry.
I should add that I was able to import a 66 MB data file produced from the same program into MMA correctly (though it still took up many many megs of memory), so I don't think the file itself is faulty.
I have also already tried using <<Utilities`MemoryConserve` and On[MemoryConserve] before importing the data.
The machine running the code is an Athlon 3200+ with 1 GB of RAM on Win XP SP2 with all available security updates.
I would be insanely appreciative to anyone that could help me out with this issue.
