[mmap:create segment failure]
|
|
|
|
You can try the following:
|
|
|
|
1. Decrease the symmetric heap area with
|
|
"-x SHMEM_SYMMETRIC_HEAP_SIZE=<value>".
|
|
2. Set "--mca sshmem_base_start_address 0" for
|
|
automatic selection by OS of virtual start address for sshmem.
|
|
|
|
This issue could also be related to CONFIG_STRICT_DEVMEM
|
|
kernel option which if enabled prevents access to physical
|
|
memory via "mmap". In this case you could try using other
|
|
sshmem components instead.
