    How to assign more CPU cores to terminal on Mac?

    Hi, all,

    When running perl scripts on our Mac (our super computer with 16 CPU cores and 32 GB RAM), I found only one core is in process (100%). Other 15 cores are less than 5%. I feel the speed is quite slow when I try to analyze large datasets. But when I run the CLC workbench, all cores are active at one time. So is there anyway I can assign CPU cores to the terminal or my perl program? Or there is other reasons I don't figure out. Hope to get help.
    Thank you in advance.

    perl cant be threaded so you would need to run a script to split the jobs into different instances of perl all running at the same time

      Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
      by SEQadmin2



      Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

      Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

      New Genomics Technologies Take Aim at Long-Standing Limits
      by SEQadmin2


      Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

      We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
