Is there a format of *.gvs files, used by GuideView OpenMP performance analyser?
The "guide.gvs" is generated, f.e. by intel's OpenMP'ed programmes with
$ export LD_PRELOAD=<path_to_icc_or_redist>/lib/libiompprof5.so $ ./openmp_parallelized_prog $ ls -l guide.gvs It s a plain text.
Here is an example of such from very short omp programme:
$ cat guide.gvs *** KAI statistics library k3301 *** Begin Task 0 Environment variables: OMP_NUM_THREADS : 2 OMP_SCHEDULE : static OMP_DYNAMIC : FALSE OMP_NESTED : FALSE KMP_STATSFILE : guide.gvs KMP_STATSCOLS : 80 KMP_INTERVAL : 0 KMP_BLOCKTIME : 200 KMP_PARALLEL : 2 KMP_STACKSIZE : 2097152 KMP_STACKOFFSET : 0 KMP_SCHEDULING : <unknown> KMP_CHUNK : <unknown> KMP_LIBRARY : throughput end System parameters: start : Wed Nov 1 12:26:52 2010 stop : Wed Nov 1 12:26:52 2010 host : localhost ncpu : 2 end Unix process parameters: maxrss : 0 minflt : 440 majflt : 2 nswap : 0 inblock : 208 oublock : 0 nvcsw : 6 nivcsw : 7 end Region counts: serial regions : 2 barrier regions : 0 parallel regions : 1 end Program execution time (in seconds): cpu : 0.00 sec elapsed : 0.04 sec serial : 0.00 sec parallel : 0.04 sec cpu percent : 0.01 % end Summary over all regions (has 2 threads): # Thread #0 #1 Sum Parallel : 0.036 0.027 Sum Imbalance : 0.035 0.026 Min Parallel : 0.036 0.027 Min Imbalance : 0.035 0.026 Max Parallel : 0.036 0.027 Max Imbalance : 0.035 0.026 end Region #1 (has 2 threads) at main/9 in "/home/user/icc/omp.c": # Thread #0 #1 Sum Parallel : 0.036 0.027 Sum Imbalance : 0.035 0.026 Min Parallel : 0.036 0.027 Min Imbalance : 0.035 0.026 Max Parallel : 0.036 0.027 Max Imbalance : 0.035 0.026 end Region #1 (has 2 threads) profile: # Thread Incl Excl Routine 0,0 : 0.000 0.000 main/9 "/home/user/icc/omp.c" 1,0 : 0.000 0.000 main/9 "/home/user/icc/omp.c" end Serial program regions: Serial region #1 executes for 0.00 seconds begins at START OF PROGRAM ends before region #1 (using 2 threads) at main/9 in "/home/user/icc/omp.c" Serial region #2 executes for 0.00 seconds begins after region #1 (using 2 threads) at main/9 in "/home/user/icc/omp.c" ends at END OF PROGRAM end Serial region #1 profile: # Thread Incl Excl Routine end Serial region #2 profile: # Thread Incl Excl Routine end Program events (total): # Thread #0 #1 mppbeg : 1 0 mppend : 1 0 serial : 2 0 mppfkd : 1 0 mppfrk : 1 0 mppjoi : 1 0 mppadj : 1 0 mpptid : 51 50 end Region #1 (has 2 threads) events: # Thread #0 #1 mppfrk : 1 0 mppjoi : 1 0 mpptid : 50 50 end Serial section events: # Serial #1 #2 mppbeg : 1 0 mppend : 0 1 serial : 1 1 mppfkd : 1 0 mppadj : 1 0 mpptid : 1 0 end *** end
