如何处理可扩展的OCR搜索的分布图像档案

string[] allFiles = Directory.GetFiles("/mount/networkshare", "*.png", SearchOption.AllDirectories);
var partitions = allFiles.Select((file, idx) => new { file, idx })
                        .GroupBy(x => x.idx % 4) // 4 worker nodes/jobs
                        .Select(g => g.Select(x => x.file).ToArray())
                        .ToArray();

RecognitionSettings settings = new RecognitionSettings();
settings.Language = Language.English;
AsposeOcr ocr = new AsposeOcr();
foreach (var file in partitions[workerIndex]) // assign index per worker/job
{
    // OCR and log
}

# Example: PowerShell job launcher
foreach ($worker in 0..3) {
    Start-Process "dotnet" "run --workerIndex $worker"
}

// Each worker runs this
foreach (var file in myPartition)
{
    try
    {
        // OCR search, save result
    }
    catch (Exception ex)
    {
        File.AppendAllText($"error_log_{workerIndex}.txt", $"{file},{ex.Message}\n");
    }
}
// After jobs finish, aggregate all result logs centrally
