[libfabric-users] FI_MR_SCALABLE on GNI

[Biddiscombe, John A.]

Apologies - I missed this


"For versions 1.5 and later, scalable is implied by the lack of any mr_mode bits being set"


So I can just leave the mode unset and check the MR_LOCAL flag.

Dear List

libfabric:16321:gni:core:ofi_check_mr_mode():545<info> Invalid memory registration mode
libfabric:16321:gni:core:ofi_check_mr_mode():546<info> Expected: FI_MR_BASIC, FI_MR_MMU_NOTIFY
libfabric:16321:gni:core:ofi_check_mr_mode():546<info> Given: FI_MR_SCALABLE
libfabric:16321:gni:domain:_gnix_ep_getinfo():597<info> [16321:1] failed ofi_check_mr_mode, ret=-61


I'm using the libfabric 1.11 tag from the git repo and according to the feature matrix, scalable memory registration is supported on gni, however, I get the above error in the logs when I ask for it in using

    fabric_hints_->domain_attr->mr_mode = FI_MR_SCALABLE;


Is the matrix incorrect, or should I keep playing with flags in case I've messed something up elsewhere?


Thanks


JB
