java - SLURM - OutOfMemoryError: GC overhead limit exceeded -

-

i have submitted sbatch job slurm.

#!/bin/bash #sbatch --job-name=freset_weighting #sbatch --output=freset.out #sbatch --error=freset.err #sbatch --time=120:00:00 #sbatch --mem=32769 #sbatch --mail-type=begin #sbatch --mail-type=end  java -jar ~/freset/freset_0.1.jar -xx:-usegcoverheadlimit -xmx32g

the job stops following error:

exception in thread "main" java.lang.reflect.invocationtargetexception     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:39)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:25)     @ java.lang.reflect.method.invoke(method.java:597)     @ org.eclipse.jdt.internal.jarinjarloader.jarrsrcloader.main(jarrsrcloader.java:58) caused by: java.lang.outofmemoryerror: gc overhead limit exceeded     @ java.util.regex.matcher.<init>(matcher.java:207)     @ java.util.regex.pattern.matcher(pattern.java:885)     @ java.util.regex.pattern.split(pattern.java:994)     @ java.util.regex.pattern.split(pattern.java:1056)

the java process should have been started -xx:-usegcoverheadlimit argument avoid error.

cheers, markus

from java usage

 usage:  java [-options] -jar jarfile [args...]            (to execute jar file)

so should specifying options "-xx:-usegcoverheadlimit -xmx32g" before "-jar myjar.jar"

java -xx:-usegcoverheadlimit -xmx32g -jar ~/freset/freset_0.1.jar

if getting error though concerned program doing make garbage collection work overtime this. suggest doing profiling figure out causing many temporary objects. question has answers tuning, gc overhead limit exceeded.

What is the difference between data design and data model(ERD) -

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
