TBD. reconfigure IP addresses for Crane.
So, how can I reconfigure the IP addresses in Crane?
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 ?
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).

Permission denied (publickey).

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) ?

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:
Benchmarking 172.16.2.243 (be patient)

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)?

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!
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 :

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 ?
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
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.
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 $PWD/../drcov.drrun64 .
I ignore this error because I think the ./drcov.drrun64 already exist in tools directory.
But then, when I continue the steps. I'm confused on when should I execute this :
Test dynamorio with the "drcov" code coverage tool.
Should I just execute it anywhere? Here is the respond when I try to execute it in crane root directory
drcov: command not found
What should I do to solve this?
In my current setup (more on this at the bottom), the execution of the command below fails:
./new-run.sh configs/apache.sh no_build proxy_only 1
In particular, the ab client cannot produce any performance benchmark.
By inspecting the logs, it boils down to the following error/problem:
ubuntu@ubuntu:~$ ./worker-run.py -a httpd -x 1 -p 1 -k 0 -c /home/ubuntu/crane -m s -i 0 --sp 1 --sd 1 --scmd 'rm /home/ubuntu/crane/apps/apache/install/logs/*; /home/ubuntu/crane/apps/apache/install/bin/apachectl -f /home/ubuntu/crane/apps/apache/install/conf/httpd.conf -k start ' --tool none --enable-lxc yes --dmt-log-output 0 --start_proxy_only no --start_server_only yes

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 !
