Re: [rvm-research] Xmx Option in Jikes

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
