How to interpret Papi output

I have collected data of Number of L2 cache misses using PAPI. I had run an MPI application with 4 threads (mpirun -np 4) and each thread reads the cache misses in L2. Each thread outputs data for every timestamp. eg:
Code:
 Timestamp              data
xxx530     thread# 0   2136
xxx531     thread# 0   3217
..           .          .
.            .          . 
.            .          .
.            .          .
xxx550      thread# 0   412334255

xxx530      thread #1    2456
xxx531      thread#1     4243
xxx532      thread #1    4567 
and so on

Now my qstn , is whether i shud add all the cache miss values at time stamp xxx530 for thread 0,1, 2 and 3 OR shud i take the max-value for thrreda0,1,2,3 for timestamp xxx530 ?

papi_decode - provides availability and detail information for PAPI preset events. Synopsis papi_decode [-ah] Description papi_decode is a PAPI utility program that converts the PAPI presets for the existing library into a comma separated value format that can then be viewed or modified in spreadsheet applications or text editors, and can be supplied to PAPI_encode_events (3) as a way of adding or modifying event definitions for specialized applications. The format for the csv output consists of a line of field names, followed by a blank line, followed by one line of comma separated values for each event contained in the preset table. A portion of this output (for Pentium 4) is shown below: * name,derived,postfix,short_descr,long_descr,note,[native,...] * PAPI_L1_ICM,NOT_DERIVED,,"L1I cache misses","Level 1 instruction cache misses",,BPU_fetch_request_TCMISS * PAPI_L2_TCM,NOT_DERIVED,,"L2 cache misses","Level 2 cache misses",,BSQ_cache_reference_RD_2ndL_MISS_WR_2ndL_MISS * PAPI_TLB_DM,NOT_DERIVED,,"Data TLB misses","Data translation lookaside buffer misses",,page_walk_type_DTMISS * Options o -a Convert only the available PAPI preset events. o -h Display help information about this utility.
