Improve mtp acceptance rate (#1499)
* wip: port MTP architecture

Ports the Multi-Token Prediction (MTP) architecture to the older `llama.cpp` codebase used by `ikllama`.

Changes include:
- Updating `llama_batch` to support `mtp_params`.
- Modifying `llama_decode_internal` (and `encode`) to handle MTP operations (Warmup, Update, Draft).
- Adding public APIs for MTP state management (`llama_set_draft_input_hidden_state`).
- Adapting the embedding extraction logic to skip MTP update passes.

* Refactors `server_slot` to support generic speculative decoding (MTP or Draft Model).

* core: enable hybrid outputs (logits + embeddings) for MTP support

* fix(mtp): correct KV-cache slot finding for updates

* fix(mtp): persist hidden states to prevent context corruption during drafting

* refactor(mtp): clean unused code

* fix(mtp): update server to new functions name

* fix(mtp): fix graph and save hidden state

* mtp: refactor integration, context params and kv cache search

* mtp: fix hidden state extraction and speculative acceptance flow

* server: fix MTP warmup for long prompts and reset token buffer

* llama: refactor MTP operation state to context parameters

* server: fix n_past calculation in MTP acceptance

* llama: fix mtp enable flags

* speculative: refactor MTP to use common_speculative interface

* context: remove unused signatures

* clip: fix deprecated enum-enum conversion warning

* common: fix format string crash in help message

* context: fix mtp activation logic

* llama: allocate all the n_outputs for MTP

* wip

* server-context: get only the last embedding for hidden state

* ggml-backend: fix array of bounds in debug build

sweep-bench: add -minilog argument to reduce verbose logging (#1468)
Purpose:
Add --minilog flag to llama-sweep-bench that filters log output to show only essential GPU/layer distribution information while suppressing verbose model metadata and per-layer device assignment messages.

Changes:
- Add llama_selective_log_callback with blacklist approach (sweep-bench.cpp)

Blacklisted patterns (hidden):
- Per-layer device assignments ('Setting default device in layer')
- KV metadata dump header and entries
- Tensor type counts
- Model validation messages
- EOG/special token cache info
- Metadata printout (llm_load_print_meta, print_info)
- Layer sizes table
- Tensor loading info (llm_load_tensors)
- Separator lines
- Most common cases of incomplete/continuation lines are also hidden

All other log output is shown, including:
- GPU VRAM info
- Split/buffer distribution per device
- Graph split estimates
- Final benchmark table and timings

Merge ffn_up and ffn_gate experts tensors (#1137)
* WIP - not working

* WIP - not working

* WIP - GPT-OSS working

However, extremely stupid. The only way I could correctly repack the
up/gate experts is to copy up and gate into host buffers, repack
into another host buffer, copy back into the ffn_up_gate_exps tensor.
This is going to be very slow for giant 500 GB models.

My attempts to do this via a compute graph on the backend holding
the tensors was unsuccessful.

For GPT-OSS-20B I see ~6-7% better PP when using the original
ik_llama.cpp fused_up_gate CUDA implementation, and ~10% when
using the small batch size implementation.

Other models are not working yet on CUDA as I need to fix the
fused mul-unary implementation.

* WIP

* WIP - Qwen3-MoE (and hopefully all others) working

But when I say here and in the previous commit "working",
I mean PP is working. TG is still broken.

* WIP: TG seems to be working

* Minor

* Add command line option to merge experts up/gate

* Add merge up/gate command line parameter to llama-bench

* Turn off merge_up_gate_exps if split mode graph

It is not yet implemented

* When no bias, allow merging up/gate with tensor overrides

* Arghh, we need to increase the context size again

* Cleanup

Kawrakow 519405dc97 Async compute graph evaluation (2 or more GPUs) (#1089)
* WIP: absorb adding input into std_attn and std_ffn

* WIP: NCCL infra

* WIP: add reduce and fake_cpy ops

* WIP

* WIP: graph appears to work, layer is broken

* WIP: Qwen3-MoE works with graph, layer still broken

* WIP: GLM-4.5 graph works

* WIP: fix sm layer (dense)

* WIP: fix sm layer (MoE)

* WIP: fast PP with bespoke 4-GPU NCCL

I guess, I'm not using NCCL the right way as PP is very
low with a single communicator group for 3 or more GPUs.
But if I create 4 communicator groups for pairs of GPUs
(0,1, 2,3, 0,2, 1,3) and use that, PP is fast: I'm hitting
1500 t/s for L3-70B on the 4x3090 system, which is
~20% better than the previous sm graph without NCCL.
But that cannot be the solution (I cannot be creating pairwise
communicators and associated logic for every possible number of GPUs).

* WIP: Cohere2

* Explicitely set device

* Bespoke 3-GPU case

* WIP

* Do not repeat get_rows multiple times

* Fix 3 GPUs

* OK, let's leave it in

* Simple async

* This sync seems enough

* Only do async for 4 or more backends

With 2 GPUs (so, 3 backends) not using async is slightly faster

* Scheduler changes

* Use OpenMP if available

Surprisingly (at least to me), this is quite a bit faster than
std::thread and std::barrier. GLM-4.5-AIR with 4 GPUs is now
at 105 t/s at zero context!

* Do not use OpenMP if there are tensor overrides

* Set omp max active levels

* Be more careful with having set the device before using a stream

* Command line option to turn on async. Set to false by defualt for now

Signed-off-by: Gabe Goodhart <ghart@us.ibm.com>

* feat: Partial support for full templating for idefics3 in mtmd

There are still errors encoding some of the image chunks, but the token
sequence now matches transformers _almost_ perfectly, except for the double
newline before the global image which shows up as two consecutive newline
tokens instead of a single double-newline token. I think this is happening
because the blocks are tokenized separately then concatenated.

Kawrakow 6b9d1bf4b4 Graph reuse (#947)
* Add mainline compatible FA command line option

* Graph reuse: add command line argument to turn it on

* WIP

* This seems to work

* This is perhaps cleaner

* Change the command line option to -gr

Kawrakow ddc88bac17 Set mla=3 by default (#943)
so more recent users that haven't followed the history of FlashMLA
evolution and hence don't know about the MLA options get the best setting
without having to add -mla 3 on the command line.

Kawrakow fb0d5a995c RoPE cache (#887)
* Introducing rope cache

When computing RoPE, the rotation angles in each layer
are exactly the same, and only depend on the token positions
(and other constant, model dependent parameters).
So, I wonder, why don't we compute the angles just once
and then reuse for the Q and K RoPE in each layer?

This commit does it as a POC on the CPU, and uses it in
the Qwen3-MoE compute graph.

* cuda: neox works

* WIP

* rope_cache: norm works

* Fused rope+rope

* Fused rope+rope (norm)

* Fused rms+rms+rope+rope (neox) - not working

* WIP

* Also qwen3

* Add command line arg to disable rope cache

* Disable RoPE cache if rope type is not neox or norm

* Add missing break after merge with main

* Fused fused_rms+fused_rms+rope+rope (with -mqkv)

* Fused fused_rms+fused_rms+rope+rope (without -mqkv)

Kawrakow 56fc5454ff Merge Q, K, V (#878)
* POC: merge Q, K, V into a single, contiguous tensor

Done just for Qwen3-MoE, where I see a 4% uplift in TG.
PP performance gain is sub-percent, if any.
Still, it seems it makes sense to do it in general given
the TG performance gain.

* WIP

* merge_qkv: it works for gpt-oss

...but we see a smaller TG gain (~1.5%)

* WIP

* Don't ignore the return value of create_tensors()

else, when q, k, v get merged and we are running on the CPU,
we get a crash because the backend is trying to use mmap,
but that no longer works.

* merge_qkv: bias can be required, optional, or mandatory

* merge_qkv: glm4.5moe

* merge_qkv: add command loine argument to enable

* merge_qkv: fix tensor dimensions

* merge_qkv: llama-4

* merge_qkv: qwen3 (dense)

* merge_qkv: simplify build_qwen3moe

* cohere2 - simplify graph building
