sdlprof: A Storage Profiler for Deep Learning Frameworks

Set up sdlprof

$ git clone git@github.com:dsrhaslab/sdlprof.git
$ cd sdlprof
$ mkdir build; cd build
$ cmake ..
$ cmake --build .
$ export PROFILER=$(pwd)/libprofiler.so

Using sdlprof

$ LD_PRELOAD=$PROFILER ./executable

Configurations

Basic configurations can be found in the file include/config.hpp.

• log_type defines if the log file created will be written in JSON format or in a format destined to easy for people to read.
• dir specifies the path where the log file will be created.
• hostname specifies the name of the machine where the program is running (this is used as part of the log name). If left empty, the program sets it to the value of the hostname.
• log_file_name specifies the name of the log file. If left empty the log file will be "log_M_D.F" where 'M' is hostname, 'D' is the datetime of creation of the log file and "F" it's extension (depends on the log_type choosen).
• reset_pid_per_op is a flag that specifies if the PIP is always rechecked at every operation intercepted (true), or if it's not necessary to do so (false).

Example

To run the test main.cpp with sdlprof execute the following commands.

$ cd ../test
$ g++ -g -o main main.cpp -ldl
$ LD_PRELOAD=$PROFILER ./main

The content of the log file obtained must be similar to the bellow.
