[Mckernel-users 29] [Problem with installation of mckernel again]

[안민우]

Hello Balazs,

I'm MS student from Korea, who sent emails about installation of mckernel(I
successfully installed before). I have 3 questions.

1.

I have some problem in my linux, so I install centOS again and I tried to
build and boot mckernel.

I successed to build mckernel(ihk+mckernel.tgz as you gave to me), but when
I tried to run mcreboot.sh script in "install/sbin" directory, my whole
server rebooted itself.

I'm sure that I disabled irqbalance and changed to SELINUX=disabled.

How can I fix my problem?

2.

Moreover, how can I find some documents(or manual) about mckernel source
code?

It is for change # of cores of mckernel. In my server, without any
modification of configuration, mckernel installed on 6 cores. Can I change
it to 8 cores?

3.

I tried to run NAS parallel benchmark in MPI version(ft.B.16), it causes
page fault(What's the problem?). Is it write to run "ft.B.16" executable
file with command "MPI_NUM_THREAD=16 mcexec {PATH_TO_EXECUTABLE}/ft.B.16" ?



Thank you to read my email.

Best regards,

Minwoo Ahn.
