- ___SYNOPSYS___
- This repository contains tests to measure the latency of IPE's DMA communication. There are several tests and they can be used with different harware configuration (BIOS or nvidia-smi changes).
- All the tests have been run on ipepascal1, so some configurations may vary with the target.
- ___DEPENDENCIES___
- It uses several internal libraries such as ddrio, pcitool or ipedma, and the gdrcopy Github repository. They all should be installed in their default location.
- ___LAUNCH___
- It is necessary to insert the gdrdrv from gdrcopy by using the provided insmod.sh script, as root.
- The executables are all located in the build directory. They need root access privilege.
- In the build directory:
- run #./reload_cmake.sh
- to generate the Makefile
- run #make
- to compile the executables
- run #LD_LIBRARY_PATH=/usr/local/lib64 ./EXEC.sh ITER
- where EXEC is the name of an executable and ITER the number of tests to run
- The outputs are the files EXEC.csv and EXEC.export.csv. The later is processed by the script to provide a more usable csv file.
- The tests may also be launched individually with:
- #CUDA_VISIBLE_DEVICES=X LD_LIBRARY_PATH=/usr/local/lib64 ./EXEC NB_BYTES
- where NB_BYTES is the number of bytes to transfer from the FPGA. It can be 256, 512, 1024, 2048, 4096, 8196 or 16384. The scripts EXEC.sh use 4096 bytes as a default.
- Use CUDA_VISIBLE_DEVICES to choose the GPU to use for the test. The X number controls this.
