        <pre>Commit 84e0b14a0a419f26d0a2f7389e06aa8e36569808
increases significantly the memory footprint of deviceRTL.
In my test,
Before
```
Free memory available on default device    :    3594 MiB
```
after
```
Free memory available on default device    :    3305 MiB
```
my GPU has only 4GB memory. MAX_SM is fixed 6. If MAX_SM is taken as the
default, the absolute memory loss is more significant.

Foot print increase by 57%</pre>
