I tried to run with the --meter perf option but that generated the following error:
['perf stat -r 1 -x, -o _perf.tmp --append', 'Rscript', '--vanilla', '/usr/local/.../r_harness.R', 'TRUE', 'FALSE', '2', 'crt.R', '']
Execution failed: [Errno 2] No such file or directory
[Errno 2] No such file or directory
The root cause seems to be how the subprocess.call command is generated:
warmup_cmd = [perf_cmd, rcmd_args, harness, harness_args,
use_system_time, str(warmup_rep), source, rargs]
As you can see in the console log at the top, the perf stat... part is a single list element. I could fix the problem by splitting the perf_cmd into a list and prepending it to the command list:
warmup_cmd = perf_cmd.split() + [rcmd_args, harness, harness_args,
use_system_time, str(warmup_rep), source, rargs]
I am using Python 2.7.6.
I'll send a patch for this and you can accept it if this is the correct way to handle the system call.
