[kepler-users] Exceeding heap size

[David Welker]

Harini,

It is really hard to say. Like I mentioned, we haven't gotten many  
complaints along this line.

Are you sure it is not your system? Why not try running your old  
version of Kepler and seeing how it performs? If it runs fast while  
Kepler 2.0 run slow in the same environment, then at least we can  
attribute it to a change in Kepler...

Then there is the question of why this is occurring with you and not  
other people? What are your hardware specs? I suppose it is possible  
that Kepler 2.0 might be pushing the limits of your hardware capacity  
while Kepler 1.0 did not. One thing to keep in mind is that in Kepler  
1.0, Ptolemy is a jar, so maybe that is somehow more efficient...

-David
