本文记录了Embench, Dhrystone, FPMark, Linpack, Whetstone, Coremark在Unmatched开发板上运行的情况。

Embench

提了issue确认Embench是否支持rv64： embench/embench-iot#159

Dhrystone

  • Dhrystone在unmatched上运行： image image

FPMark

测试在unmatched，使用最新的GNU工具链编译FPMark并运行。

编译native GNU工具链

在x86上交叉编译rv64 native GNU工具链。

$ cd riscv-gnu-toolchain
$ mkdir build-riscv-native && cd build-riscv-native/
$ ../configure --prefix=/home/cxo/opt-riscv-native
$ make linux-native -j 52

报错：

cfenv:77:11: error: 'feupdateenv' has not been declared in '::'

解决方法： https://gcc.gnu.org/bugzilla/attachment.cgi?id=51747&action=edit

编译运行FPMark

运行命令：

$ export C_INCLUDE_PATH=/home/chenxiaoou/opt-riscv-native/sysroot/usr/include
$ export CPLUS_INCLUDE_PATH=/home/chenxiaoou/opt-riscv-native/sysroot/usr/include
$ export LD_LIBRARY_PATH=/home/chenxiaoou/opt-riscv-native/sysroot/usr/lib:/home/chenxiaoou/opt-riscv-native/native/lib:/home/chenxiaoou/opt-riscv-native/sysroot/lib
$ export LIBRARY_PATH=/home/chenxiaoou/opt-riscv-native/sysroot/usr/lib:/home/chenxiaoou/opt-riscv-native/native/lib:/home/chenxiaoou/opt-riscv-native/sysroot/lib
$ sudo /sbin/ldconfig6
$ cd fpmark_1.5.3126
$ make certify-all XCMD='-c4'

Result

(unmatched016 /home/chenxiaoou/fpmark_1.5.3126/builds/linux64/gcc64/cert/22_04_11_08_02_43/linux64.gcc64.mark) image image

-v0

默认开启了校验模式，lu程序的校验无法通过，也就没有最后Mark Result，可以通过-v0关闭校验。

命令：

make certify-all XCMD='-c4 -v0'

出错的cert_mark.pl line 338

printf "%-47s %10.2f %10.2f %10.2f\n", $mark, $best, $single, $best / $single

Linpack

源码：

http://reports.ias.ac.in/report/21074/detecting-floating-point-exceptions-in-risc-v-using-gcc

编译命令：

gcc -O -o linpack linpack.c -lm

运行结果： image

Whetstone

源码：

http://reports.ias.ac.in/report/21074/detecting-floating-point-exceptions-in-risc-v-using-gcc

编译命令：

gcc -O -o whetstone whetstone.c -lm

Coremark

unmatched的系统信息：

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 21.04
Release:        21.04

在unmatched上执行：

$ cd coremark_v1.0
$ make clean
$ make XCFLAGS="-DMULTITHREAD=4 -DUSE_FORK" ITERATIONS=150000 PORT_DIR=rv64

结果如下：
