• memory allocator now uses monagement, monagement
• feature to set limitations
  • change limitations based on driver capabilities,check:

use arr_o_gpu::ArrOgpuModule;
fn main() {
    let module = ArrOgpuModule::default();
    let driver_limit = module.get_adapter_limit();// driver limit
    let device_limit = module.get_device_limit();// limit used by the device
}

• execute_opt feature,provides the option to set workgroup_size.The operation that can do this currently:
  • add
  • sub
  • mul
  • div
  • matmul
    • matmul_2d
      • note:using 2 dimensions.if set to 16 then 16x16=256
    • matmul_nd
      • note:similar to matmul_2d,but dim z cannot be set yet
• The use of execute_opt depends on the limitations.The maximum storage can also be increased by changing the limitations,for example:

use arr_o_gpu::{AddOpt,ArrOgpuModule,FunctionExecuteOpt,HeapSize,WgpuLimits};
fn main() {
    let module = ArrOgpuModule::init(arr_o_gpu::ArrOgpuModuleInit {
        limits: WgpuLimits {
            max_storage_buffer_binding_size: 256 << 20,// 256MiB
            max_compute_workgroup_size_x: 512,
            ..Default::default()
        },
        function_execute_opt: FunctionExecuteOpt {
            add: AddOpt {
                compute_workgroup_size_x: 512,// max_compute_workgroup_size_x must be 512
            },
            ..Default::default()
        },
        heap_size: HeapSize::Item(39321600),// 150MiB
        ..Default::default()
    });
}

• expanding max_storage_buffer_binding_size,must pay attention to max_buffer_size

use arr_o_gpu::{ArrOgpuModule,WgpuLimits};
fn main() {
    let module = ArrOgpuModule::init(arr_o_gpu::ArrOgpuModuleInit {
        limits: WgpuLimits {
            max_storage_buffer_binding_size: 512 << 20,
            max_buffer_size: 512 << 20,
            ..Default::default()
        },
        ..Default::default()
    });
}

• fixed a bug in matmul due to the difference in override names on the wgsl and rust sides
• resolved the matmul_nd_view.wgsl bug, in the form of tile_b not being updated
• resolved the matmul_nd_view.wgsl bug, which was a logic error in mapping the location of the value array from metadata
• add testing code
