Java process from corner analysis

Hi all,

I run analog artist with cadence 5.032 on redhat 7.3

When I run corner analysis, I see many java process appear (up to 8 process
every time I run it). All these process use up the system memory (32M each).
Is it normal to have that many java process running in the same time???? I
use to see up to 36 java process that use up to 1G of memory.
I have to quit Cadence completely to remove these process.

Do any body have an idea on what happening ???

Thank.
 
PS: When I run ic5.032 on a Sun machine. Only one java process appear

It seems to be something Linux specific - and I believe it is a generic Java
(jre) problem - I'm not sure it is under the control of Cadence but the jre
implementation?

I've seen the same problem on Linux too.

Thank for the information. Is ther any way that we can have a report of the
true memory used for the java process ??

Hi Tritue,

I am not sure, if there is any easy way to show the actual memory
being shared by all the Java threads, but you can always use the "/proc"
filesystem for finding out the memory usage of any process(or thread
reported as process in this case) on a linux system. The system resource info.
for any process could be found under "/proc/<pid>/status".
You should be able to track the increase in process memory usage
by looking at the "VmData" field.

Hope this helps you.

Regards
Raman

There is an option to not load the corners Java junk. Add the
following to your .cdsinit:

envSetVal("asimenv" "loadCorners" 'boolean nil)

Actually, the "more correct" way is to add the line:

asimenv loadCorners boolean nil

to your .cdsenv file.
