[Corpora-List] SVD problem again! (SVD on large matrix)

Hi Fangzhong,

try to allocate more resources:

java -Xms<some_min_size> -Xmx<some_max_size>

-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size

With some "heavy" applications, I usually use the following command
which works fine:

java -Xms32m -Xmx512m MyHeavyProgram

Cheers
Joćo Paulo
