+___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.
