The ldpc\_perf\_collect.py Python script from the cuPHY repository can be used to perform error rate tests for the cuPHY LDPC decoder. Currently, there are test input files defined for Z = [64, 128, 256, 384], BG = [1,2]. The current tests check whether the block error rate (BLER, also sometimes referred to as Frame Error Rate or FER) is less than 0.1.
From the build directory, the following commands will run the tests:
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG1\_Z64\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG1\_Z128\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG1\_Z256\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG1\_Z384\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG2\_Z64\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG2\_Z128\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG2\_Z256\_BLER0.1.txt -f -w 800 -P
../util/ldpc/ldpc\_perf\_collect.py --mode test -i
../util/ldpc/test/ldpc\_decode\_BG2\_Z384\_BLER0.1.txt -f -w 800 -P
Each test input file contains multiple tests for different code rates, as specified by the number of parity nodes. The format of the input files has the following form:
# BG Z num_parity num_iter SNR max_BER max_BLER
#--------------------------------------------------------------
1 384 4 10 6.87 1 0.1
1 384 5 10 6.15 1 0.1
1 384 6 10 5.64 1 0.1
1 384 7 10 5.17 1 0.1
1 384 8 10 4.79 1 0.1
...
After running each of the test cases, the ldpc\_perf\_collect.py script will display an output table:
+-----------------------------------------------------------------------------------------------------------+
| # BG Z num\_parity num\_iter SNR max\_BER BER max\_BLER BLER STATUS |

Max_threads specifies the maximum number of process threads. The default value is 64 threads. To improve performance, the lock-free mechanism doesn’t use Compare-And-Swap, but needs to configure a maximum thread number.
Usage
String Tags
To print with a string tag, define a string TAG in code and use it directly:
#define STAG "NVLOG.STAG"
NVLOGI(STAG, "This is STAG C printf style log. level=%d\\n",LOG\_INFO);
NVSLOGI(STAG) << "This is STAG C++ stream style log. level=" <<LOG\_INFO << "\\n";
To print with a pre-defined integer tag, define an integer TAG in nvlog\_config.yaml:
nvlog\_tags:
- 10: "NVLOG" # nvlog
- 11: "NVLOG.TEST"
- 12: "NVLOG.ITAG"
Then use the integer TAG in code:
#define NVLOG\_TAG\_BASE\_NVLOG 10 // nvlog
#define ITAG (NVLOG\_TAG\_BASE\_NVLOG + 2) // "NVLOG.ITAG"
NVLOGI(ITAG, "This is ITAG C printf style log. level=%d\\n", LOG\_INFO);
NVSLOGI(ITAG) << "This is ITAG C++ stream style log. level=" << LOG\_INFO << "\\n";
