crane's Issues

DynamoRio Installation

When I tried to follow the README installation,
I got an error when I tried to setup the DynamoRio:

ln: failed to create symbolic link ‘./drcov.drrun64’: File exists

I got this when I tried to run this code :

cd tools && ln -s $PWD/../drcov.drrun64 .

I ignore this error because I think the ./drcov.drrun64 already exist in tools directory.
But then, when I continue the steps. I'm confused on when should I execute this :

Test dynamorio with the "drcov" code coverage tool.

Should I just execute it anywhere? Here is the respond when I try to execute it in crane root directory

drcov: command not found

What should I do to solve this?

TBD. reconfigure IP addresses for Crane.

I found this sentence on README.

Compile libevent_paxos.

cd $MSMR_ROOT/libevent_paxos
./mk
make clean; make

TBD. reconfigure IP addresses for Crane.

So, how can I reconfigure the IP addresses in Crane?

boost::interprocess::interprocess_exception with apache tests

In my current setup (more on this at the bottom), the execution of the command below fails:

./new-run.sh configs/apache.sh no_build proxy_only 1

In particular, the ab client cannot produce any performance benchmark.
By inspecting the logs, it boils down to the following error/problem:

The 'no such file or directory' is not clear to what it refers exactly.
The u1 LXC container (into which the parallel-ssh command is executing to) has all the files.
Have you already seen this ?

I wonder if this is due to my current setup, and thus I'd be grateful if you could clarify something: is it possible to use Crane with services operating inside virtual machines (using KVM as hypervisor) ?
Or else, there is a strict requirement for them to be physical machines ?
In your evaluation (SOSP paper, section 7) you do specify the hardware spec of the replica machines, but not if those host virtual machines.
Thanks !

env variables $MY_PROXY and $MY_XTERN

The script apacheinstallbinapachectl relies on the existence of those two variables:

# Start the application server
if [ $MY_XTERN"X" = "1X" ]; then
LD_PRELOAD=$XTERN_ROOT/dync_hook/interpose.so \
$MSMR_ROOT/apps/apache/install/bin/apachectl -f $MSMR_ROOT/eval/current/server7000/httpd7000.conf -k start &> ../server7000/${TEST_NAME}_0_${NO}_s${LOG_SUFFIX} &
REAL_SERVER_PID_0=$!
else
$MSMR_ROOT/apps/apache/install/bin/apachectl -f $MSMR_ROOT/eval/current/server7000/httpd7000.conf -k start &> ../server7000/${TEST_NAME}_0_${NO}_s${LOG_SUFFIX} &
REAL_SERVER_PID_0=$!
fi

echo "sleep some time"
sleep ${SLEEP_TIME}

# Start our proxy
if [ $MY_PROXY"X" = "1X" ]; then
${SERVER_PROGRAM} -n 0 -r -m s -c ${CONFIG_FILE} -l ./log 1>./log/node_0_${NO}_stdout 2>./log/node_0_${NO}_stderr &
fi

Those variables are defined by the eval.py script that generates the apacheinstallbinapachectl :
https://github.com/columbia/crane/blob/master/eval/eval.py#L315
https://github.com/columbia/crane/blob/master/eval/eval.py#L324

Could you explain where those variables should point to ?
Thanks

Minimal Working Example Errors

Hello! I've written a very simple echo server in Python and am trying to replicate the server using crane. I've read through the instructions in the README which led me to read new-run.sh, worker-run.py, worker-build.py, master.py, etc. I couldn't run those scripts out of the box, so I tried to write the simplest script I could to replicate the server without them.

I want to run with three servers (running on 127.0.0.1:7000-7002) and three proxies (running on 127.0.0.1:9000-9002). For simplicity, I want to run all three servers and all three proxies on the same machine with Parrot but without LXC. I have the following two config files, which (I hope) set this up properly:

I run this command three times to run the three proxies. This command succeeds.

libevent_paxos/target/server.out -n $i -r -m s -c nodes.local.cfg -l ./proxy_logs

Then, I ran this to start the servers:

xtern/scripts/wrap-xtern.sh python server.py 700$i

Unfortunately, this does not work. Running this prints

terminate called after throwing an instance of 'boost::interprocess::interprocess_exception'
  what():  No such file or directory

I read through the code and found that the first second line of code in paxq_open_shared_mem inside of paxos-op-queue.cpp is throwing the exception. It looks like there are some files that it expects to exist inside of /dev/shm that don't exist. Do I have to make some files first before running my server? I noticed the paxq_create_shared_mem function above, but it is never called in the code. I added a call to it myself and then the server runs! But, unfortunately when I try to connect a client to a proxy, the messages are not being delivered.

Long story short, I want to replicate a simple server with crane as simply as possible and am running into some troubles. Any help or guidance would be greatly appreciated!

/PAXOS_OP_QUEUE is too small for this app

Executing a benchmark that hammers the Crane proxy with several requests, the proxy stops working. On the primary's logs, we find:

/PAXOS_OP_QUEUE-valerio is too small for this app. Please enlarge it in paxos-op-queue.h

We've tried several different values by changing the value of the ELEM_CAPACITY here: https://github.com/columbia/crane/blob/master/xtern/lib/runtime/paxos-op-queue.cpp#L34

Is that the right variable to change ? It doesn't seem to produce beneficial effects on our benchmark.

Problem with ./eval.py *cfg

I've followed the instructions in:
https://raw.githubusercontent.com/columbia/crane/master/README.md

Everything goes smoothly. Then, I try to execute the eval.py scripts.
First, it requires the installation of matplotlib:

sudo apt-get install libfreetype6-dev && sudo pip install matplotlib

Then, once executed I got the following errors.
Does it have to be executed from the host machine (ubuntu), or from the container's machine (u1) ?

sched_setaffinity fails (xtern?)

We're getting a bunch of these in our deployment:

https://gist.github.com/vschiavoni/8a3f756604aaa6967fd481923ddc3083#file-error_log

httpd: /home/valerio/crane/xtern/obj/./../dync_hook/annotation_hooks.cpp:170: void tern_init_affinity(): Assertion 'sched_setaffinity(0, sizeof(mask), &mask) == 0' failed.
The errors are in the error_log file of apache when using the joint_sched option
The code that fails is here:

https://github.com/columbia/crane/blob/master/xtern/dync_hook/annotation_hooks.cpp#L170

Any idea of why this can happen ?

hardcoded Columbia IPs in new-run.sh

Currently the new-run.sh file has hardcoded hostnames pointing to Columia machines:

# Update worker-run.py to the server
scp worker-run.py bug03.cs.columbia.edu:~/
scp worker-run.py bug01.cs.columbia.edu:~/
scp worker-run.py bug02.cs.columbia.edu:~/

How should we change those ? Without modifying those, executing the new-run one gets these:

Permission denied (publickey).
lost connection
Permission denied (publickey).
lost connection
Permission denied (publickey).

Support for Docker ?

Hi,
can Crane work with Docker instead of LXC ? Is there some inherent limitation or it should work (more or less) out of the box ?

How should I setup IPs of three replicas and one client machine?

I'm not a RCS@Columbia team, so how should I replace the need of 3 replica machines and one client machine?

I tried to use the ubuntu@u1 IP, and create two IP aliases, but it doesn't work.

When I tried to execute

./new-run.sh configs/apache.sh no_build joint_sched 1

I got this error :

/home/jeff/Programs/crane/eval-container

low throughput requests ?

Hi,
i've finally been able to setup a Crane cluster (1 client, 3 replicas) and launch 2 of the benchmark scripts for Apache (./new-run.sh configs/apache.sh no_build orig 1, and ./new-run.sh configs/apache.sh no_build proxy_only 1). Interestingly, I get strangely low request rate results from ApacheBench.
In the case of (./new-run.sh configs/apache.sh no_build orig) I get:

In your SOSP paper there is not mention of the raw performances, and plots report relative results.
Do you mind sharing such numbers (even privately via email if you prefer)?
