Usage:

Change to directory where files are, then start benchmarking by issuing the following command:

For a full run:

sudo ./cpu2006express.sh -c

Customized run:

sudo ./cpu2006express.sh [OPTIONS]

TODO:

1. Add config flags xml
2. Isolate floating-point run errors

Adding Additional Systems:

If your system isn't being detected:

1. Add something simpler to this below line 184 in the cpu2006express.sh file:

   • Change YOUR_SYSTEM_KEYWORD to the keyword infront of your processor name in the /proc/cpuinfo file.

############################################################

If CPU is still empty

This is mainly for X systems

Example: X

############################################################ if [ -z "$CPU" ]; then CPU=$(grep 'YOUR_SYSTEM_KEYWORD' /proc/cpuinfo | uniq | sed 's/YOUR_SYSTEM_KEYWORD\s*:\s//g') fi

2. Add something simpler to this below line **[296](https://github.com/ryanspoone/CPU2006-Express/blob/master/cpu2006express.sh#L296)** in the **[cpu2006express.sh](https://github.com/ryanspoone/CPU2006-Express/blob/master/cpu2006express.sh)** file:
+ Change ***`YOUR_SYSTEM`*** to your processor name in the **`/proc/cpuinfo`** file.
+ Change ***`YOUR_SYSTEM_CONFIG`*** to your config file name.

```bash
elif [[ $CPU == *'YOUR_SYSTEM'* ]]; then
 export GCC_CONFIG='YOUR_SYSTEM_CONFIG'

3. Add your machine information to user_input.sh.
4. Make sure your system is using the -march= flag, otherwise you might want to add a case to line 274 in the cpu2006express.sh file.
   • I had to add PowerPC this way because they use -mcpu instead.

Runspec Errors:

/usr/bin/ld: cannot find -lm and/or /usr/bin/ld: cannot find -lc

• RHEL: remove -static from the compiler flags in the config file.

copy 0 non-zero return code or other build errors.

Change the portability options for that benchmark. Here are some options:

• -DSPEC_CPU_LP64
  • This macro specifies that the target system uses the LP64 data model; specifically, that integers are 32 bits, while longs and pointers are 64 bits.
• -DSPEC_CPU_Linux
  • This macro indicates that the benchmark is being compiled on a system running Linux.
• -DSPEC_CPU_Linux_X64
  • This macro indicates that the benchmark is being compiled on an AMD64-compatible system running the Linux operating system.
• -DSPEC_CPU_Linux_IA32
  • This macro indicates that the benchmark is being compiled on an Intel IA32-compatible system running the Linux operating system.
