    I had read that page, but still didn't understand completely. A colleague was able to help out. If anyone else comes to this post for clarification: for two intervals, I needed to submit 2 separate jobs to my cluster:

    gatk --java-options "-Xmx40g" HaplotypeCaller -pairHMM AVX_LOGLESS_CACHING_OMP --native-pair-hmm-threads 32 -L contigs_1_of_2.list -R $ref -I $bam -O gVCF_files/$sampleName.g.vcf -ERC GVCF

    gatk --java-options "-Xmx40g" HaplotypeCaller -pairHMM AVX_LOGLESS_CACHING_OMP --native-pair-hmm-threads 32 -L contigs_2_of_2.list -R $ref -I $bam -O gVCF_files/$sampleName.g.vcf -ERC GVCF

    Where the .list files each contain half of your data worth in contig names. You can combine the .vcf files afterward following the instructions provided by Broad Institute
