--0-1785890333-1175760321=:87268 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Hi, I am running an application on system having 32GB RAM and of 64 bit architecture in Red Hat Enterprise Linux AS release 3 (Taroon). The program would build a model from a large input file "train.arff". The command I am using as: java -Xss5g -Xmx5g -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps weka.classifiers.functions.MultilayerPerceptron -t train.arff -d model The program is running since 8-10 hours and its not crashing neither it is generating the model. It is generating the GC output like 5481.444: [GC 5481.444: [DefNew: 644672K->80509K(725184K), 0.6994480 secs] 1561522K->1321698K(2336480K), 0.6996100 secs] 5511.990: [GC 5511.991: [DefNew: 725181K->80507K(725184K), 0.6670090 secs] 1966370K->1642470K(2336480K), 0.6671440 secs] 5525.390: [GC 5525.390: [DefNew: 725173K->80509K(725184K), 2.8566000 secs]5528.247: [Tenured: 2084314K->986867K(2084384K), 7.4814160 secs] 2287136K->986867K(2809568K), 10.3582090 secs] 5561.876: [GC 5561.876: [DefNew: 657920K->82236K(740160K), 0.8334260 secs] 1644787K->1431620K(2384944K), 0.8335680 secs] 5592.279: [GC 5592.279: [DefNew: 740156K->82236K(740160K), 1.3097720 secs]5593.589: [Tenured: 1766389K->992572K(1766512K), 7.8476160 secs] 2089540K->992572K(2506672K), 9.1627900 secs] 5631.679: [GC 5631.679: [DefNew: 661824K->82681K(744512K), 0.7424000 secs] 1654396K->1417559K(2398800K), 0.7425390 secs] 5641.293: [GC 5641.293: [DefNew: 744505K->82675K(744512K), 1.7965000 secs]5643.090: [Tenured: 1889028K->936375K(1889040K), 8.3549570 secs] 2079383K->936375K(2633552K), 10.1621330 secs] If I provide less memory the program ends up with OutOfMemoryError. Can anybody suggest me if I am allocating wrong memory to the application. Regards, Soumyadeep --------------------------------- 8:00? 8:25? 8:40? Find a flick in no time with theYahoo!
