UNIX for Advanced & Expert Users

I have a small question on crontab entry. I need to run around 1000 jobs at a time from cron. these are small checks which will complete in a second.
is my queuedefs is capable of handling that many jobs at atime. do i need to do any modifcations to my ulimit settins. What is the maximum no of concurrent jobs i can run using cron.

This is MP-RAS unix which follows system V release 4 standards.

Thanks in advance

See this thread about limits on cron

Thaks for the info. According to that thread i can run only 100 concurrent jobs at a time.
I have other question.if i want to run 100jobs ( the jobs run time will be around one sec ) at a time is there any way i can do this using some script. or do i need to specify 100entries in crontab file with same time.

Thanks in advance

One script would be easier - and remember, cron can run 100 jobs at a time - if your jobs are really only running for a second, it should be able to get through the 1000 jobs quickly (it matters on what other cron jobs are running when you kick this off).

Till now what i undestood is we can run only 100 concurrent jobs using cron. Eventhough they are one sec jobs or 10min jobs. How the concurrent runtime makes different depending on the job runtime, can you please give me more details about that.
In my situation i need to start all 1000 jobs on same second.

Can you give me more idea about the scrip.
