Max memory usage of different process in a single bash file

I am wondering if there is any way to compare the peak memory usage of different process in bash script. I want to compare the memory usage of different program which are working in the same data set. my bash file is something like below:

 #!/bin/bash
 ./program_1 parameterSet1
 ./program_2 parameterSet2
 ./program_3 parameterSet3

I want to store the max memory usage of each process separately. It might be useful to point out that each program takes several minutes to finish, how can i monitor max memory usage of that program simultaneously. Should I write another bash script?

Many thanks in advance

/usr/bin/time -f "process 1 max RSS %M kbytes" ./program1 parameterSet1
/usr/bin/time -f "process 2 max RSS %M kbytes" ./program2 parameterSet2

Will put the maximum resident set size on stderr for the program. You can tailor the format string (as I did) or redirect outputs to trace each separate process.
