Full graph parallel for Qwen3.5 (dense and MoE) (#1388)
* WIP

* WIP

* WIP

* WIP

* WIP

* WIP

* WIP

Loads and starts running, crashes with illegal memory access in
quantize_mmq_q8_1. This almost always indicates NaNs in the input
to the MoE FFN part.

* WIP

* WIP

Loads and runs, wrong results (very high PPL)
Performance looks promising, around 25% better than previous sm graph.
Needs f32 or bf16 graph reduce type.

* WIP - still wrong

* Fix after rebase

* WIP

* WIP

* This seems to be working for dense Qwen3.5!!!

* WIP: Qwen3-Next is not quite working

* Some cleanup

* Disable Qwen3-Next for now

* Disable graph parallel when mmproj was specified

* Read/write split recurrent state

* That should not crash

* Re-enable vision - it works now

* Recurrent layers should now be counted for split cache

Fix compilation on clang-cl.exe (#1355)
Fixes https://github.com/ikawrakow/ik_llama.cpp/issues/1169

See bitwise ariphmetics here: https://clang.llvm.org/doxygen/avx512fintrin_8h_source.html

Clang (and GCC) supports a language feature called Vector Extensions.

To Clang, `__m512i` is not just a "struct" or a "bag of bits"; it is recognized by the compiler as a native vector type.
Because it is a native vector type, Clang automatically maps standard C operators to the corresponding hardware instructions.
When you write `a | b`, Clang sees that a and b are 512-bit integer vectors.
It implicitly understands that the bitwise OR operator (|) applies to these vectors.
It automatically generates the VPORQ (or VPORD) instruction without needing any helper function.

MSVC follows a stricter, more traditional C++ model regarding intrinsics.

In MSVC, __m512i is defined in the header files (<immintrin.h>) as a struct or union (e.g., typedef struct __m512i { ... } __m512i). To the MSVC compiler, it is essentially a user-defined data type, not a fundamental language primitive like int or float.
Standard C++ does not define what `|` means for a user-defined struct.
MSVC does not have the same "Vector Extensions" that automatically apply operators to these structs.
When you write `a | b` in MSVC, the compiler looks for a definition of `operator|` for the __m512i struct. Since the standard headers don't provide one, the compiler throws an error.
You must use the explicit intrinsic function provided by Intel/MSVC: _mm512_or_si512(a, b).

To get the nice syntax `(a | b)` in MSVC, you have to manually "teach" the compiler what `|` means by defining the `operator|` overload yourself.

gguf-split: fix the split output files naming (#1336)
* Fix gguf-split.cpp splits output naming

With this fix, the initial extension of the source .gguf file is not included in the naming of the output file before the numeration of the splits.

ex:

No more model.gguf-00001-of-00200.gguf
Instead, model-00001-of-00200.gguf

* Minor

* Revert "Discard unnecessary changes in llama-build-context.cpp"

This reverts commit edadb80ed68c4c0831e9c22609a9a3af19be9735.

* Increase GGML_SCHED_MAX_SPLITS - required for larger u-batches

* Fix CPU concat in the TG case: 7.25 -> 10.5 t/s for Qwen3Next

* Fix CPU sum_rows: 10.5 -> 13.6 t/s for Qwen3Next

It was single-threaded and was taking ~25% of the computation time
during TG. It is now down to 2%.

Strangely enough, I measure 13.6 t/s with llama-bench, but if I
let the model give me an actual response with llama-cli, I get close
to 17 t/s.

* Fix CPU scale: 13.6 -> 16.7 t/s for Qwen3Next

For Qwen3Next there is a scale op on a largish tensor (548k elements)
that has a single row for TG, so was done in a single thread.
We now simply use blocks of 1024 elements.

* Optimize CPU mul: 16.7 -> 17.6 t/s for Qwen3Next

* CPU: fuse transpose -> cont -> sum_rows -> transpos: 17.6 -> 23.1 t/s for Qwen3Next

* Optimize CPU repeat: 176 -> 200 t/s for Qwen3Next PP-512

* Multithreading for OP_SUB

* Don't commit with timing trace on

* Multithread neg and sigmoid

* Be able to turn on/off fusion more easily (CPU)

* Name the mul_mat ops so we know where the time goes

* WIP

* Much better PP on CUDA

* CUDA: fuse transpose -> cont -> sum_rows -> transpose

Needs non-coontiguous variant of sum_rows.
On the CPU this gave 30+% improvement in TG performance,
on CUDA ist is disapointing 6-7%. I guess, this is because
Georgi's cont CPU implementation was so bad that skipping
it made such a big difference.

* CUDA: faster mul for special case relevant for Qwen3Next

Worth 1% in TG

* Fix CPU OP_CONT

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

* WIP: absorb adding input into std_attn and std_ffn

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

* 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

Kawrakow a719349982 POC: CUDA tensor parallel (MoE models) (#1022)
* Remove most of split mode row

* WIP

* WIP: also allocate the KV cache using tensor split

* WIP: it runs with wrong result

But it also looks like the backend scheduler is not going to help:
* It copies mask and input positions to GPU 0
* => RoPE ops must run on GPU 0
* => To proceed attn evaluation, GPU 1 must wait for GPU 0 to finish its
     entire attn calculation
* Same with FFN. The rms_norm gets scheduled on GPU 0. Hence, GPU 1 must
  wait for GPU 0 to finish its entore FFN calculation before it can
  start (as it needs to copy the result of rms_norm from GPU 0)
* => Seems useless without writing a bespoke TP scheduling

* WIP

* This works, but it is slow

* This is slightly better

the graph is still not being computed in parallel.
Why? Because the scheduler creates graph splits where the
result of the computation on one GPU becomes an input for the
other split. Hence, to trigger the computation on the second GPU
one needs to wait for the computation on the first GPU to finish,
even thiough the two can be done in parallel up to the sunchronization
point. So, all that is left to do is to trick the scheduler to create
to splits that can be done in parallel, and then have a graph split
where the results get combined.

* Playing games with the scheduler

This change tricks it into doing the right thing^TM.
Still quite a bit slower than split mode layer for the 8B LlaMA model.
But for the 70B LlaMA it now beats split mode layer for TG:
28 t/s vs 24.4 t/s. PP is 627 t/s vs 744 t/s.
In comparison, split mode "row" in mainline gets
484 t/s PP and 19.3 t/s TG.

* Fix attn split

Granularity for Wq, Wo is not just head size, but
head size * gqa_ratio.
Else the Wk, Wv tensors end up not being a multiple of the
head size when we divide the split determined by Wo with
the gqa_ratio.

* Show memory used per device

* Make it work with partial offload

but no tensor overrides yet, just ngl < num_layers.

* Allow for f16 source in fused_rms_norm

* This results in faster PP.

Now PP is faster than split mode layer for L3-70B.

* Rename split mode "row" to split mode "graph"

* Leave FFN partial results as f16

* WIP GLM4.5 - runs with wrong results

* WIP GLM4.5 - this works

PP is already better than split mode layer, but TG for zero context
is kind of low - 60 vs 92 t/s. TG becomes better than split mode layer
at around 20k tokens. PP at 26k tokens is 1.55X of sm layer.

* Work around compiler bug

It issues a warning that there is an extra semicolon outside of a function,
but there isn't. If I remove the anonymous namespace and turn the
functions inside into static, the warning disapears, so clearly
a compiler bug.

* Make graph reuse work with split mode graph

* Remove more split mode row remnants

* WIP tensor overrides

Runs with wrong results, don't see where the issue could be.

* This works but is slow

Still does not work for row-interleaved quants

* Slightly better

* Slightly better

* Row-interleaved quants work

* Better

* Minor

* Guarad against using split mode "graph" for unsupported models

* Guards against using merge_qkv with split mode "graph"

* WIP split mode attn

Works for LlaMA models, but not for GLM-4.5.
Doesn't seem to improve performance, so I guess no point in trying to
fix it.

* Split mode graph for qwen3moe

* Try to better distribute the splits

because the blocks are tokenized separately then concatenated.

Nexes the Elder 9a63e768ea Legacy quants cpy_blck_q_f16 function for K cache (#1001)
Shortfixes the bug : ggml\src\ggml-cuda\cpy.cu:614: ggml_cuda_cpy_fn: unsupported type combination (q6_0 to f16) encountered when trying to use deepseek lite v2 with quantized K cache. Note: I compile my IK_Llama with GGML_CUDA_F16.

To fix this, I added a cpy_blck_q_f16 function devised by comparing the cpy_blck_q8_0_f32 and cpy_blck_q8_0_f16, and transposing the difference for the other legacy quants on the basis of the cpy_blck_q_f32 function. A "rule of three" of sorts.

Perplexity test and inference now works consistantly on -ctk q4_0 ; q4_1 ; q5_0 ; q5_1 in that scenario, with expected values and behavior.

Except on Q6_0, which sees its perplexity multiplied by 100. (I suspect the Cuda dequantize_q6_0 to be incompatible with this PR for some reason, but that's beyond what I can fix)

-ctk iq4_nl, which doesn't have yet a dequantize_iq4_nl function, is not usable that way for now.

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

* 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 4e24d48e63 Attention mask tweaks for better long context performance (#825)
* Parallelize mask

We see non-negligible PP gains for long contexts.
More importantly, the strange drop in performance
observed for GPT-OSS for context >= 32k tokens is gone.

* Whith FA on, create mask as f16 directly

* WIP

* Reduce KQ mask padding to 16

Why was it 64 in the first place?

I don't observe any issues, while TG performance
for long contexts improves by 2-4%.

Kawrakow a9eeef53f3 Fix q8_0 repacking issues on AVX2 (#708)
Q8_0 needs Q0_0_X4, but Q8_0_R8 needs Q8_2_X4.
So, if we decide to repack a Q8_0 MoE tensor to Q8_0_R8,
iqk_moe_fused_mul_unary fails because the activations were
prepared as Q0_0_X4, but we now need Q8_2_X4.

For now a simple fix: just take the slow path, do not repack.
