Check Transfer

Check Transfer

Purpose of the program

Program for check data transfer between host and Xilinx OpenCL device

Resource

• Doxygen documentation: https://dsmv.github.io/sdaccel/check_transfer/index.html
• Project page: https://github.com/dsmv/sdaccel/projects/1

Main properties

The program is developed on the basis of a TF_Test, TF_TestThread and TableEngineConsole templates that was developed in conjunction with Vladimir Karakozov. (https://github.com/karakozov) The program in console application that can work in two modes:

• with test table - for direct launch and launch from Qt
• without test table - for launch from SDAccel and launch on Nimbix server

Test table is a text table with status information:

• BlockWr - count of written blocks
• BlockRd - count of read blocks
• BlockOk - count of correct blocks
• BlockError - count of incorrect blocks
• SPD_CURRENT - velocity of data transfer for last 4 seconds
• SPD_AVR - velocity of data transfer from test start

Preview:

• check_transfer - preview with table mode
• check_transfer - preview without table mode

There are two test classes:

• TF_CheckTransferOut - check data transfer from HOST to device
• TF_CheckTransferIn - check data transfer from device to HOST

Arguments:

• -table <flag_show> : 1 - show table, 0 - do not show table, default 0
• -time : execution time [s], default 10
• -file : fullpath for xclbin, default: "../binary_container_1.xclbin"
• -size : size block of megabytes, default 64
• -metric : 0 - binary: 1MB=2^10=10241024=1048576 bytes; 1 - decimal: 1MB=10^6=10001000=1000000 bytes
• -mode : 1 - check input, 2 - check output, 3 - check input and output

Results:

1 MB = 2^10 = 1024*1024 = 1048576 bytes

Size of block = 256 MiB = 268435456 bytes
