+You write custom CUDA kernels to replace the pytorch operators in the given GeGLU architecture to get speedups.
+
+You have complete freedom to choose the set of operators you want to replace. You may make the decision to replace some operators with custom CUDA kernels and leave others unchanged. You may replace multiple operators with custom implementations, consider operator fusion opportunities (combining multiple operators into a single kernel, for example, combining chunk+gelu+elementwise_mul), or algorithmic changes (such as optimized memory access patterns). You are only limited by your imagination.
+
+This CUDA kernel implements optimized Double Gated Linear Unit (Double GLU) with:
+
+Memory Optimization:
+
+Vectorized memory access using float4 for 4x bandwidth
+
+Contiguous tensor inputs for coalesced memory access
+
+Processes two GLU pairs simultaneously per thread
+
+Parallelization Strategy:
+
+Grid-stride loop for efficient workload distribution
+
+256 threads per block optimal configuration
+
+Automatic grid size calculation with 65535 block limit
+
+Computational Optimization:
+
+Double GLU: Two parallel GLU operations sigmoid(gate) * activation
+
+Optimized sigmoid: 1.0f / (1.0f + expf(-x))
+
+Fast math compilation flags for optimized exponential
+
+Efficient indexing for four input chunks (G1, X1, G2, X2)
+
+Work Distribution:
+
+Each thread processes 8 total elements (4 per GLU pair) via float4
+
+Processes two independent GLU operations simultaneously
+
+Input divided into four equal chunks, output into two chunks
+
+Requires input feature dimension divisible by 16 for optimal performance
+
+The implementation maximizes throughput by processing two GLU operations in parallel through vectorization and efficient memory access patterns.
+
+Here's an example to show you the syntax of inline embedding custom CUDA operators in torch: The example given architecture is:
+import torch
+import torch.nn as nn
+import torch.nn.functional as F
+
+class Model(nn.Module):
+    def __init__(self):
+        super().__init__()

+        return torch.cat([torch.sigmoid(g1) * x1, torch.sigmoid(g2) * x2], dim=-1)
