I am using version 1.8.3.
I can install the latest version 1.8.4 & see if that changes the result....

Hello,

I am new to HD5.


I am trying to create many many number of groups ; however, the below piece of code hangs,

chr1_id = H5Gcreate(file_id, "/chr1", H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);
   for (i = 1; i <= 247249719; i++){
       k = sprintf(pos, "%d", i);
group_id = H5Gcreate(chr1_id, pos, H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);
       status = H5Gclose(group_id);
   }

whenever i attempt to create, say, 1000 groups, it works just fine..
is there a maximum number of groups that an H5 structure supports?

am I doing some wrong?

   Looks fine to me.  What version of the HDF5 library are you using?

   Quincey
