Re: [rvm-research] Xmx Option in Jikes

Do you really mean -Xmx20480M

Try -Xmx2048M

Here is the command I tried

sudo ./dist/FullAdaptiveMarkSweep_x86_64-linux/rvm "-X:perf:frequency=7500"
"-X:perf:enabled=true"
"-X:perf:counters=PAPI_SR_INS,PAPI_TOT_CYC,PAPI_TOT_INS"
"-X:perf:package_counters=PAPI_L3_TCM" "-X:perf:accumulate=true" "-
Xmx20480M"  cache_misses

Error Message: vm: "-Xmx20480M" is not a recognized Jikes RVM command line
argument.

I also tried "-X:Xmx20480M" and "-X:Xmx=20480: and still same error message

  The order is wrong. It should read "java -Xmx2048M HelloWorld". If you
  use "java HelloWorld -Xmx2048M", you'll pass the argument "-Xmx2048M" to
  the HelloWorld program which isn't what you want.

  What's the error message you're getting?


  Kind regards,
