Hi all,
Recently our lab purchased a workstation with 64 GB RAM, xeon processor (which has 64 cores) running on 64bit linux. I am connected to it through a desktop (linux 64bit) which has 4GB RAM, i5 processor (4 cores). I previously used to work on this desktop and now that I am connected to workstation, I thought of comparing the alignment speed on both machines.
Data I used is paired end, with each 1.3 GB.
I am using bowtie2 to align. (reference genome is yeast)
On workstation I had set threads (-p) argument to 58 cores, and on desktop I used 3 cores out of available 4.
Alignment results are same on both machines but the time taken by them is drastically different.
Desktop machine took 8:39 secs, whereas
Workstation took 18:18 secs !!!!!!!!
What might be the problem ??
I am sorry if my question is not relevent to the forum.
Thank you !
