Question

prov/ofi_rxm Not working, Need core provider, skipping ofi_rxm

jordialcaraz opened this issue 4 months ago · comments

Describe the bug
I'm trying to execute an application with FI_PROVIDER=ofi_rxm, but it fails to find ofi_rxm. Tried the same with fi_pingpong to check if the problem was the application or not, but fi_pingpong also fails.
Then I tried fi_getinfo, which returns -61 (No data available) when FI_PROVIDER=ofi_rxm, but it appears with fi_info.

To Reproduce
Steps to reproduce the behavior:
FI_PROVIDER=ofi_rxm FI_LOG_LEVEL=Debug fi_info

Expected behavior
Should print the same output as fi_info.

Output
$ FI_PROVIDER=ofi_rxm FI_LOG_LEVEL=Debug

This is not a bug. You need to use verbs;ofi_rxm as shown from your fi_info output.

Thanks Chien.

I had also tried with verbs;ofi_rxm, but although fi_info works, fi_pingpong fails (it looks for ofi_rxm at the end, instead of verbs;ofi_rxm):

verbs supports msg endpoints (you would need -e msg argument)
verbs;ofi_rxm supports rdm endpoints (you would need -e rdm argument)

You can run fi_info -v -p verbs to view the full set of supported capabilities and endpoint types

Chien Tin Tung · Answer 6 · Fri Feb 16 2024 06:40:53 GMT+0800 (China Standard Time)

From your fi_info and log, I'm guessing you do not have IPoIB set up. fi_pingpong requires either IPv4 or IPv6 address. After you have that configured, use verbs;ofi_rxm with -e rdm, that should work for you.
