File locking when using hdf5, collective mode #10
In aiori-HDF5.c, the line 295
memDataSpaceDims = (hsize_t) param->transferSize;
invokes strided io in the romio ADIO layer (ad_write_str). The line should be
memDataSpaceDims = (hsize_t) param->transferSize / sizeof(IOR_size_t);
After changing this line of code, the configuration works without file locking.

My program crashed and I got the following error output:
"File locking failed in ADIOI_Set_lock(fd 13,cmd F_SETLKW/7,type
ADIOI_Set_lock:: Function not implemented"
