[Polly] Use three-dimensional arrays to store packed operands of the matrix multiplication

[gareevroman]

Summary

Previously we had two-dimensional accesses to store packed operands of the matrix multiplication for the sake of simplicity of the packed arrays. However, addition of the third dimension helps to simplify the corresponding memory access, reduce the execution time of isl operations applied to it, and consequently reduce the compile-time of Polly. For example, in case of Intel Core i7-3820 SandyBridge and the following options,

clang -O3 gemm.c -I utilities/ utilities/polybench.c -DPOLYBENCH_TIME -march=native -mllvm -polly -mllvm -polly-pattern-matching-based-opts=true -DPOLYBENCH_USE_SCALAR_LB -mllvm -polly-target-cache-level-associativity=8,8 -mllvm -polly-target-cache-level-sizes=32768,262144 -mllvm -polly-target-latency-vector-fma=7

it helps to reduce the compile-time from about 361.456 seconds to about 0.816 seconds.

For example, getAddressFunction() can return the following map . Subsequently, Memory::applyScheduleToAccessRelation tries to apply the schedule to its domain.

AFAIU this changes isl_map_lexmin to be called after applying the schedule, instead of before.

What I don't understand where the compile-time improvement comes from. Does isl_map_lexmin spend that much time? Why is it different depending on when it is applied? Are there other cases where calling isl_map_lexmin late will take more time than when applied early?

Maybe the problem is that the access relation needs to be simplified. Try calling isl_map_compute_divs, isl_map_detect_equalities and isl_map_coalesce on it before isl_map_lexmin. This already helped me in one case.

Wouldn't it make more sense to check for the access relation instead for the generated code?

I mean, there are a lot suffix digits in the checks which can change easily with otherwise unrelated changes, including with LLVM itself.

The change is also unrelated to matrix-multiplication optimization. Is there a simpler test case?

If I understand your summary correctly, this is only a compile-time optimization. How can there be a test case?

Hi Michael,

thanks for the comments!

I've updated the patch. It adds the third dimension to an array that stores a packed operand of the matrix multiplication, which, as far as I understand, helps to simplify the corresponding memory access and avoid the issue with isl_map_lexmin.

AFAIU this changes isl_map_lexmin to be called after applying the schedule, instead of before.

Sure.

What I don't understand where the compile-time improvement comes from. Does isl_map_lexmin spend that much time? Why is it different depending on when it is applied? Are there other cases where calling isl_map_lexmin late will take more time than when applied early?

Since the simplification of the memory accesses helps to avoid the issue, I propose to postpone the discussion.

Maybe the problem is that the access relation needs to be simplified. Try calling isl_map_compute_divs, isl_map_detect_equalities and isl_map_coalesce on it before isl_map_lexmin. This already helped me in one case.

It doesn't help in this case. However, thanks for the advice.

Yes, we could probably check the access relation, if it could be incorrect.

The change is also unrelated to matrix-multiplication optimization. Is there a simpler test case?

I think that the new version of the patch doesn't require a new test case.

If I understand your summary correctly, this is only a compile-time optimization. How can there be a test case?

Right. It probably makes sense to provide more details about the reason of the compile-time regression.

What is the access relation it is derived from?

It represents an access to the A, the first operand of the matrix multiplication. It also requires the specific values of LatencyVectorFma, ThroughputVectorFma, CacheLevelAssociativity, and CacheLevelSizes (e.g., 7, 1, 8, 8, 32768, 262144, respectively) to reproduce the issue.

If it is that complex as well, we should consider ensuring that we do not generate that complicated access functions.

Right.

Interesting.

Could you add some more information to the commit message:

1. Give before/after compile times for a specific example
2. Explain why we previously had 2D accesses

Also, I see that besides the helper function, no comments changed. It would be good to add documentation how the packing transformation is implemented. Possibly with a simple example.

Also, as Michael suggested, we should consider factoring a separate function that implements packing and is only paramterized for the A/B array.

[grosser]

Obviously, the refactoring is not a requirement for this patch to in and should better be done separately. If it is easy, I suggest to do it first.

[Meinersbur]

Accept for the patch itself. Tobias suggested a more detailed commit message.

Hi Tobias,

I've updated the commit message.

Also, I see that besides the helper function, no comments changed. It would be good to add documentation how the packing transformation is implemented.

I think that the comment to optimizeDataLayoutMatrMulPattern gives a brief overview of how the packing transformation is implemented. What do you think about it?

Possibly with a simple example.

What do you think about the following example:

"As an example let us consider the packing of the array A, which is represented by an assess relation that has the form { Stmt_for_body6[i0, i1, i2] -> [o0, o1, o2, o3, o4, o5, o6, o7, 0] : 256*floor((-i2 + o5)/256) = -i2 + o5 and 8*floor((-i1 + o7)/8) = -i1 + o7 and 4*floor((i0 - o6)/4) = i0 - o6 and -15 + i1 <= 16o0 <= i1 and -255 + i2 <= 256o1 <= i2 and -95 + i0 <= 96o2 <= i0 and 0 <= o5 <= 255 and 0 <= o6 <= 3 and 0 <= o7 <= 7 and -7 + i1 - 8o3 <= 16*floor((i1)/16) <= i1 - 8o3 and -3 + i0 - 4o4 <= 96*floor((i0)/96) <= i0 - 4o4 }

To add a new array Packed_A[24][256][4] to the SCoP, we use Scop::createScopArrayInfo(). Copying of data to the array is performed by the copy statement created by Scop::addScopStmt. Changing of the memory access locations to {Stmt_for_body6[i0, i1, i2] -> [o0, o1, o2] : 256*floor((-i2 + o1)/256) = -i2 + o1 and 4*floor((-i0 + o2)/4) = -i0 + o2 and 0 <= o1 <= 255 and 0 <= o2 <= 3 and -3 + i0 - 4o0 <= 96*floor((i0)/96) <= i0 - 4o0} is performed by MemoryAccess::setNewAccessRelation."

Probably, it makes sense to commit such a comment separately.

Obviously, the refactoring is not a requirement for this patch to in and should better be done separately. If it is easy, I suggest to do it first.

Yes, the refactoring is probably required since r278666. At the moment, it seems that a parametrized packing would have too many parameters (e.g., parameters of new memory accesses, domains of copy statements, sizes of dimensions of newly created arrays).

I'll fix a few issues related to the optimization and the identification of the matrix multiplication and start working on the refactoring.

Why is the _access_ relation mapping to a 9 dimensional space. You talk about a _schedule_ here, right?

To add a new array Packed_A[24][256][4] to the SCoP, we use Scop::createScopArrayInfo(). Copying of data to the array is performed by the copy statement created by Scop::addScopStmt. Changing of the memory access locations to {Stmt_for_body6[i0, i1, i2] -> [o0, o1, o2] : 256*floor((-i2 + o1)/256) = -i2 + o1 and 4*floor((-i0 + o2)/4) = -i0 + o2 and 0 <= o1 <= 255 and 0 <= o2 <= 3 and -3 + i0 - 4o0 <= 96*floor((i0)/96) <= i0 - 4o0} is performed by MemoryAccess::setNewAccessRelation."

The access relation seems to implement a modulo constraint. It probably is easier to read if we write the modulo explicitly. I suggest to just submit a patch with this comment, then Michael and me can read over it and see if we still have some comments.

Probably, it makes sense to commit such a comment separately.

Right.
