Providing Transactional Semantics Instructions to install the modified Virtual Machine

The project should contain the following folders:

  • jamvm
  • tinySTM
  • classpath
  • tests

Inside classpath directory:

  • ./configure --without-x --disable-gtk-peer --disable-gconf-peer --disable-plugin --disable-tools --disable-examples
  • make clean
  • make
  • make install

There may be an error while compilling. Find the Makefile in that folder, search for AM_CFLAGS and add -fno-strict-aliasing

Inside the tinySTM directory:

  • Verify that the following configurations in the Makefile are as described:
  • DEFINES += -DDESIGN=WRITE_BACK_ETL (other two are disabled)
  • DEFINES += -DCM=CM_DELAY (other three are disabled)
  • DEFINES += -UIRREVOCABLE_ENABLED
  • DEFINES += -UNO_DUPLICATES_IN_RW_SETS
  • DEFINES += -DWAIT_YIELD
  • DEFINES += -UUSE_BLOOM_FILTER
  • DEFINES += -UEPOCH_GC
  • DEFINES += -UCONFLICT_TRACKING
  • DEFINES += -UREAD_LOCKED_DATA
  • DEFINES += -ULOCK_IDX_SWAP
  • All debugs are off
  • DEFINES += -DRW_SET_SIZE=4096000
  • CFLAGS += -fPIC
  • make clean
  • make

Inside the jamvm directory:

  • Inside lib folder: ln -s ../../tinySTM-1.0.0/lib/libstm.a libstm.a
  • Inside src folder: ln -s ../../tinySTM-1.0.0/include/stm.h stm.h
  • Inside src folder: ln -s ../../tinySTM-1.0.0/include/wrappers.h wrappers.h
  • ./configure
  • Modify the generated Makefile in src/: LIBS = -lz -ldl -lm -lpthread ../lib/libstm.a
  • Modify the generated Makefile in src/interp/: LIBS = -lz -ldl -lm -lpthread ../../lib/libstm.a
  • Modify the generated Makefile in src/interp/engine/: LIBS = -lz -ldl -lm -lpthread ../../../lib/libstm.a
  • make clean
  • make
  • make install

Inside the tests directory:

  • For each package tN in packages t1-t7, compile with javac tN/TestAll.java
  • For package t8, compile with javac t8/TestCounterTiny.java & javac -cp t8/build/jvstm.jar:. t8/TestCounterJVSTM.java
  • For package t9, compile with javac t9/TestTransfersTiny.java & javac -cp t8/build/jvstm.jar:. t9/TestTransfersJVSTM.java
  • For each package tN in packages t11-t13, compile with javac tN/Main.java
  • Run each of the compiled tests with the jamvm executable and the parameters required by the program.
  • Run again with a pristine version of the JamVM to compare the results, or remove the @Atomic annotations.
