My total memory is 48GB*2 memory:

```

❯ free -h
               total        used        free      shared  buff/cache   available
Mem:            93Gi       6.8Gi        75Gi       2.8Gi        12Gi        83Gi
Swap:           95Gi       1.5Gi        94Gi

```


Thank you, I should decrease `mps_gen_param_s` to use less memory.

Hello,
I'm helping to test scratch/igc branch on my local environment:
```
❯ uname -a
Linux Matrix 6.6.41 #1-NixOS SMP PREEMPT_DYNAMIC Thu Jul 18 11:21:27
UTC 2024 x86_64 GNU/Linux
```

I get the source code of scratch/igc, commit hash: 6682d0e6c96 .
And I append a new commit:
```
diff --git a/src/igc.c b/src/igc.c
index f069a2becc9..4d792da75c8 100644
--- a/src/igc.c

 }
AFAIU, the above requests MPS to create a generation chain whose
capacity is 128GB.  How much memory do you have on that system?
