Does 4080 support Distributed Shared Memory？Thanks!!!

#2

are you referring to shared memory in the new threadblock cluster capability?

#3

yes…seems only in H100, which is avail until Jan next year, right?

#4

Yes, that is a hopper feature. 4080 is not a Hopper GPU. It is a member of the Ada Lovelace family of GPUs. Hopper is compute capability 9.0 or 9.x. 4080 is a compute capability 8.9 device.

#5

Seems even 4090 is not…So only H100 can?

#6

Yes, Table 14: CUDA C++ Programming Guide
