Micro Benchmark Tester

Contents

1. caller

The migration script, it has 4 args and run migration of benchmark 3 times

- test benchmark binary name
- target machine, user@ip
- the sender script, depends on criu branch, there are two sender for both archtectures
- alternative args, some benchmark need args, for example _popcorn-mm 4096_

2. x86-64/

The x86 sender and receiver scripts for migration

- arm_x86_receiver: recevier for x86 to handle migration from arm to x86
- x86_arm_sender: sender for x86 to handle migration from x86 to arm **CRIU branch: heterogeneous**
- x86_arm_sender_antonio: sender for x86 to handle migration from x86 to arm **CRIU branch: crit-in-criu**
- Makefile: install script to /user/local/bin/

3. aarch64/

The aarch sender and receiver scripts for migration

- x86_arm_receiver: recevier for arm to handle migration from x86 to arm
- arm_x86_sender: sender for arm to handle migration from arm to x86 **CRIU branch: heterogeneous**
- arm_x86_sender_antonio: sender for arm to handle migration from arm to x86 **CRIU branch: crit-in-criu**
- Makefile: install script to /user/local/bin/

4. TEST/

The popcorn-npb-is_c binaries for test.

Pre-requisites

1. Recommended system Linux Linux 4.15.0-45-generic
2. Recommended os Ubuntu 16.04
3. CRIU branch heterogenous-simplified. (recommended)

$ git clone https://github.com/systems-nuts/criu.git
$ git checkout hetterogeneous-simplified
branch crit-in-criu
$ git checkout crit-in-criu (alternative)

4. Inorder to use script, target machines should have ssh public key to avoid password.

sudo su
ssh-keygen
paste ~/.ssh/id\_dsa.pub to your target machine: ~/.ssh/authorized\_keys

5. root permission
6. Popcorn-compiler

$ git clone  https://github.com/systems-nuts/popcorn-compiler.git
$ git checkout criu

Environment set up

Create same work directory on both machines, path: /popcorn/brdw.

mkdir /popcorn/brdw
cp benchmark/\* /popcorn/brdw
cp caller /popcorn/brdw

Script installation

• On aarch64

cd aarch64 ; make

• On x86-64

cd x86-64 ; make

Test

cd /popcorn/brdw/
./caller $sender_script $benchmark $targetmachine $args

there are two $sender_script, depends on criu branch

1. $benchmark is test binary,

2. $targetmachine is tagetmachine user@ip or alias,

3. $args is for some binary for example: ./popcorn-mm 4096

Build:

Example for x86 to ARM, benchmark: popcorn-npb-is_c, CRIU: heterogeneous

mkdir -p /popcorn/brdw/

cp ./TEST/popcorn-npb-is_c\* /popcorn/brdw/

cp caller /popcorn/brdw/

cd x86-64

make

ssh to aarch64 machine

mkdir -p /popcorn/brdw/

cp ./TEST/popcorn-npb-is_c\* /popcorn/brdw/

cp caller /popcorn/brdw/

cd x86-64

make

cd popcorn/brdw/

./caller x86_arm_sender popcorn-linpack sunsky 

Example calling if benchmark needs fourth args (popcorn-mm)

./caller x86_arm_sender popcorn-mm sunsky 4096  

Example for ARM to x86, benchmark: popcorn-npb-is_c, CRIU: crit-in-criu

mkdir -p /popcorn/brdw/

cp ./TEST/popcorn-npb-is_c\* /popcorn/brdw/

cp caller /popcorn/brdw/

cd x86-64

make

ssh to aarch64 machine

mkdir -p /popcorn/brdw/

cp ./TEST/popcorn-npb-is_c\* /popcorn/brdw/

cp caller /popcorn/brdw/

cd x86-64

make

cd popcorn/brdw/ 

./caller x86_arm_sender_antonio popcorn-linpack sunsky  

Example calling if benchmark needs fourth args (popcorn-mm)

./caller x86_arm_sender_antonio popcorn-mm sunsky 4096    

Known bug

1. Depends on machine, when to greb the process id, the script could run in some case

modify the line 26 on sender script and line 13 on receiver script.
	
pid=$(ps -C $process | tr -s ' '  | cut -d ' ' -f 2 | tail -n +2)  
 	
 IF PID IS EMPTY, pleae change it between **"cut -d ' ' -f 2"** and  **"cut -d ' ' -f 1"** 

2. (NEW UPDATE)

Latest popcorn-compiler will not have flash quit problem, 

while [ -z "$pid" ] loop may delete( line 25 on sender and line 12 on receiver)

the purpose of this loop is to make sure benchmark run successfully
