|
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.

[mmap:file open failure]

|
|
|
|
|
|
|
You can try the following:
|
|
|
|
|
|
|
|
|
|
1. Switch to anonymous mapping using "-mca sshmem_mmap_anonymous 0".
|
|
|
|
|
The anonymous mapping is not backed by any file.
|
|
|
|
|
2. Set path to backing files explicitly using "-mca sshmem_base_backing_file_dir <path>"
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
You can try to switch to anonymous mapping using "-mca sshmem_mmap_anonymous 0".
|
|
|
|
|
The anonymous mapping is not backed by any file.
