PAPI 4.2.0 Fails "make test" on Intel Core i7-2630QM

Postby francesquini » Tue Dec 13, 2011 1:05 pm


I'm starting to use PAPI now, and as a newbie I have some questions. After configuring and compiling with no errors I get the following output from "make test":

80000034 PAPI_FP_INS is not available.
Test case 0: start, stop.
Default domain is: 1 (PAPI_DOM_USER)
Default granularity is: 1 (PAPI_GRN_THR)
Using 20000000 iterations of c += a*b
Test type : 1
PAPI_FP_INS : 47810264166936
PAPI_TOT_CYC : 183860549
Real usec : 66883
Real cycles : 133463693
Virt usec : 66819
Virt cycles : 53456000
Verification: PAPI_TOT_CYC should be roughly real_cycles
Error of 27.41%
zero.c FAILED
Line # 117
Error: validation

make: ** [test] Erro 1

When I try to run "make fulltest", for almost every test I got the following
./ctests/timer_overflow.c: 2: not found
./components/coretemp/tests/coretemp_basic.c: 21: Syntax error: "(" unexpected
/components/cuda/tests/ 10: Syntax error: newline unexpected

Although is on the same directory, when I run it, it gives:
emilio@xisto:~/papi-4.2.0/src$ ./
box, tab(&);
lt | lw(50).
./ 12: ./tests/avail: not found

I simply cannot make heads or tails of it. Any advice?

The PAPI_TOT_CYC error you get is likely because your CPU is doing some sort of frequency scaling or turbo boost that is changing the clock frequency while the test runs. This is normal.

The other error you get is because the PAPI tests run by running all files marked as executable in the ctests directory. It looks like somehow all of your C files got marked executable somehow.
