Dear Lin, Based on you explanation, I’m guessing you’re trying to install everything by yourself and run the benchmark bare metal. If so, is there any particular reason for that? We’ve recently released CloudSuite V3 which is based on Docker images and simplifies the installation process. We’ve created images with all the required packages installed; so you can run the benchmarks without the hassle of installing everything by yourself. For the Data Caching benchmark, you can take a look at this page<http://cloudsuite.ch/datacaching/>, which explains how to run the docker-based version of this benchmark. If you are not familiar with Docker, I recommend you to check the Docker website<https://www.docker.com> and documentation<https://docs.docker.com> first. Let us know if you need any more help.

However I can not use it successfully. I show what I run and the error messages,Would you like to help me use this benchmark? A) Build Memcached 1. libevent We installed the library at the default location not use ./configure --prefix=/path/to/folder/ to change the location. The following messages are displayed. Is it no problem for simulation? "make[3]: Nothing to be done for `install-exec-am'." "make[3]: Nothing to be done for `install-data-am'." 2. Memcachd We installed it at the default location. PATH/memecached-1.4.15/.configure PATH/memecached-1.4.15/make PATH/memecached-1.4.15/sudo make install The following messages are displayed. Is it no problem for simulation? "make[4]: Nothing to be done for `install-exec-am'." B) Staring the server run /PATH/memcached-1.4.15$ memcached -t 4 -m 4096 -n 550 Shall we keep it running when we do the simulation? C) Preparing the client In memcached/memcached_client/, we just run make, because we installed libevent at the default location, About prepare the serve configuration file, Would you like to tell me where is the configuration file? Shall we add the server_address and port number into the configuration file? The server_address is an address of a real server? and port too? How i can get these information? D) about Scaling the dataset and warming up the server We run ./loader -a ../twitter_dataset/twitter_dataset_unscaled -o ../twitter_dataset/twitter_dataset_30x -s servers.txt -w 1 -S 30 -D 4096 -j -T 1 the following messages are displayed. stats_time = 1 Configuration: nProcessors on system: 4 nWorkers: 1 runtime: -1 Get fraction: 0.900000 Naggle's algorithm: False -- message host: 192.168.9.116 address: 192.168.9.116 host: 192.168.10.116 address: 192.168.10.116 Number of client (worker) threads must be divisible by the number of servers E) Ruuning the benchmark We run ./loader -a ../twitter_dataset/twitter_dataset_30x -s servers.txt -g 0.8 -T 1 -c 200 -w 8 The following error messages are displayed. stats_time = 1 Configuration: nProcessors on system: 4 nWorkers: 8 runtime: -1 Get fraction: 0.800000 Naggle's algorithm: False host: 192.168.9.116 address: 192.168.9.116 host: 192.168.10.116 address: 192.168.10.116 Segmentation fault (core dumped) Would you like to tell me what shall I do or test to help me using the benchmark. Best Wishes, Lin Meng.
