Run SPEC CPU2006 on Linux with either an Intel, ARM, or PowerPC processors.

SPEC CPU2006 Express

This harness performs SPEC CPU2006 benchmarking using GCC. Capabilities include in installing prerequisites, building and installing SPEC CPU2006, and running reportable integer and floating-point runs.

Note: You must provide the cpu2006 tar archive.

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.
