Yes, it opens today at 7 UTC (I think), I should be able to fill the form

Uhh, I meant user-defined aliases here. Don't know why I wrote "format", it
makes no sense. An example for aliases would be:

#define result v7
v_mov_b32 result, 2

Update on the DS format: realhet replied to my post on the AMD forums (

I did get the DS format working using GDS, but the LDS size is still a
mystery to me. The code that realhet linked to (
has a reference to ldsSize in the si_bin_compute_pgm_rsrc2_t struct. I have
to look at the code a bit further to find where the lds size is actually

By the way, this code is from Multi2Sim which is a CPU-GPU simulator. It
looks interesting.

0. None, I was away for the week

0. Fill the midterm evaluation form
1. Find out more about LDS size
2. Work on DS instructions and see if we can improve performance that way
3. Figure out an automated way to measure the performance gain/loss of
"optimized" kernels
