Knime hangs up

KNIME Analytics Platform
1

Hello,

I have a table consisting of 48 Columns and 850.000 Rows. The subject matter are numbers. I work with an x64 PC with an Intel Pentium CPU G4500 @ 3.50 GHZ with 8 GB RAM and Windows Enterprise.

I tried to do a principal component analysis (PCA node) and an multidimensional scaling analysis (MDS node). In both cases knime hangs up. Is this amount of data to much for my PC configuration? Can I make this work?

 

Best regards

wbart

Hi Wbart,

did you change your knime.ini file and adjusted the Xmx parameter to e.g. 7GB? This parameter defines how much memory KNIME is allowed to use. The number of rows is quite substantial, so you need to increase this setting as much as possible.

Cheers, Kilian
