[mvapich-discuss] Errors with MVAPICH2-0.9.3

[LEI CHAI]

Hi Amit,

Thank you for your report.

The error "sched_setaffinity: Bad address" is because sched_setaffinity does not work on Linux 2.4 kernel. Upgrading to Linux 2.6 will solve this problem. If you want to stay with 2.4 kernel for the time being you can specify this environment variable when you run the program: 

-env VIADEV_ENABLE_AFFINITY 0

Hope this helps.

Thanks.

Lei
