The problem about async memory limit? #31

Closed lj-cug closed 1 year ago

lj-cug commented 2 years ago

Dear Sir: When I use HDF5 VOL-Async within HDF5 1.13.1, and I run my app with async I/O of HDF5. The information like "ASYNC ABT INFO 0 write size 18920009385957 larger than async memory limit 23632764928, switch to synchronous write It seems like I haven't set some Environmental Variable in my system? Now the async mode can not function well. Thanks Li Jian

Hi @lj-cug does your application work without vol-async? You can verify by doing export HDF5_VOL_CONNECTOR="" before you run your code. Also, can you check how much data are you writing? 18920009385957 is number of bytes that vol-async calculated for the write size, which doesn't seems to be a valid value.
