Hi,
I downloaded the last version of the Lustre ADIO driver on mpich2-1.1rc1.
I saw that the parametre len_list_ptr of function ADIOI_Calc_my_off_len()
has been modified in include/adioi.h:
int **len_list_ptr (32 bits) has been changed to
ADIO_Offset **len_list_ptr (64 bits)
So, I propose to change in ad_lustre_aggregate;c, line 122:
void ADIOI_LUSTRE_Calc_my_req(ADIO_File fd, ADIO_Offset *offset_list,
int *len_list, int contig_access_count,
<==== here is the change
int *striping_info, int nprocs,
int *count_my_req_procs_ptr,
int **count_my_req_per_proc_ptr,
ADIOI_Access **my_req_ptr,
int **buf_idx_ptr)
And in ad_lustre_wrcoll.c, line 84 :
ADIO_Offset *offset_list = NULL, *st_offsets = NULL, *end_offsets =
NULL, *len_list = NULL;
int *buf_idx = NULL, *striping_info = NULL;
instead of:
ADIO_Offset *offset_list = NULL, *st_offsets = NULL, *end_offsets =
NULL;
int *buf_idx = NULL, *len_list = NULL, *striping_info = NULL;
Without these changes, len_list[i] (where i is 1,3,5,7 ...) in the routine
ADIOI_LUSTRE_Calc_my_req
are null.
I will now pass some tests and I hope make contributions.
