GATK：HaplotypceCallerIntelPairHmm僅檢測1個執行緒

我似乎無法讓 GATK 識別可用執行緒的數量。我在 conda 環境中運行 GATK (4.2.4.1)，它是我正在撰寫的 nextflow (v20.10.0) 管道的一部分。無論出于何種原因，我都無法讓 GATK 看到有多個執行緒。我嘗試了不同的節點型別，增加和減少可用的 cpu 數量，提供 java 引數，例如-XX:ActiveProcessorCount=16, using taskset，但它總是只檢測到 1。

這是來自的命令.command.sh：

gatk HaplotypeCaller \
  --tmp-dir tmp/ \
  -ERC GVCF \
  -R VectorBase-54_AgambiaePEST_Genome.fasta \
  -I AE12A_S24_BP.bam \
  -O AE12A_S24_BP.vcf

這是.command.log檔案的頂部：

我在廣泛的研究所網站上發現了一個帖子，暗示它可能是 OMP 庫，但這似乎已加載，我正在使用他們建議更新到的版本...

不用說，這有點慢。我總是可以使用該-L選項進行并行化，但這并不能解決管道中的每一步都會非常慢的問題。

提前致謝。

uj5u.com熱心網友回復：

萬一其他人有同樣的問題，我不得不將提交配置為 MPI 作業。

所以在我使用的 HPC 上，這里是 nextflow 程序：

process DNA_HCG {
  errorStrategy { sleep(Math.pow(2, task.attempt) * 600 as long); return 'retry' }
  maxRetries 3
  maxForks params.HCG_Forks

  tag { SampleID "-" chrom }

  executor = 'pbspro'
  clusterOptions = "-lselect=1:ncpus=${params.HCG_threads}:mem=${params.HCG_memory}gb:mpiprocs=1:ompthreads=${params.HCG_threads} -lwalltime=${params.HCG_walltime}:00:00"

  publishDir(
    path: "${params.HCDir}",
    mode: 'copy',
  )

  input:
  each chrom from chromosomes_ch
  set SampleID, path(bam), path(bai) from processed_bams
  path ref_genome
  path ref_dict
  path ref_index

  output:
  tuple chrom, path("${SampleID}_${chrom}.vcf") into HCG_ch
  path("${SampleID}_${chrom}.vcf.idx") into idx_ch
  
  beforeScript 'module load anaconda3/personal; source activate NF_GATK'

  script:
  """
  mkdir tmp
  n_slots=`expr ${params.GVCF_threads} / 2 - 3`
  if [ \$n_slots -le 0 ]; then n_slots=1; fi
  taskset -c 0-\${n_slots} gatk --java-options \"-Xmx${params.HCG_memory}G -XX: UseParallelGC -XX:ParallelGCThreads=\${n_slots}\" HaplotypeCaller \\
    --tmp-dir tmp/ \\
    --pair-hmm-implementation AVX_LOGLESS_CACHING_OMP \\
    --native-pair-hmm-threads \${n_slots} \\
    -ERC GVCF \\
    -L ${chrom} \\
    -R ${ref_genome} \\
    -I ${bam} \\
    -O ${SampleID}_${chrom}.vcf ${params.GVCF_args}
  """
}
