I have created a ticket 704 (<A HREF="https://trac.mcs.anl.gov/projects/mpich2/ticket/704#preview">https://trac.mcs.anl.gov/projects/mpich2/ticket/704#preview</A>) for this problem. We can proceed with discussions on that ticket.<BR>

Subject: [mpich-discuss] Problem with ROMIO using Windows<BR>
<BR>
Hi all,<BR>
<BR>
I am using coll_perf.c in order to evaluate some optimizations at ADIO level under Windows. Tracing ADIOI_Flatten_datatype primitive in Windows, I got the following wrong values for flat->count and cur_idx.<BR>
<BR>
C:\Users\fjblas>mpiexec -n 4 coll_perf.exe -fname myfile<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
ADIOI_Flatten_datatype:: count 10, cur_idx = 10<BR>
<BR>
<BR>
I traced ADIOI_Flatten_datatype primitive and I have found that ADIOI_Count_contiguous_blocks did not return the correct value for <BR>
flat->count.<BR>
<BR>
On a Linux cluster, I tried the same application without problem, and I have got correct values for flat->count.<BR>
<BR>
I tried with different versions of MPICH2 under Windows (1.0.5, 1.0.8, and the lasted release), and I have got the same incorrect values for <BR>
flat->count.<BR>
<BR>
It is possible that is something wrong under Windows???<BR>
<BR>
<BR>
Thanks for all<BR>
