<div class="">Hi Phillip,</div>
<div class=""><br class="">
</div>
<div class="">Since you are specifying an FI_EP_RDM in your hints I assume you want to utilize the RXM provider on top of the Verbs core provider (i.e. ofi_rxm;verbs). The Verbs provider does not offer native FI_RDM_EP support. To use either XRC (or FI_EP_RDM
endpoint) you will have to use RXM, but I am unaware of any IB provider that supported XRC that did not support RC.</div>
<div class=""><br class="">
</div>
<div class="">If you issue a 'fi_info -p verbs -v’ it will list all the verbs domains supported and the underlying protocol and you could verify if RC should be supported (via RXM for FI_EP_RDM). If you issue 'fi_info -p “ofi_rxm;verbs”', you should see multiple
domains for the “ofi_rxm;verbs” provider combination. XRC domains have the “-xrc” suffix.</div>
<div class=""><br class="">
</div>
<div class="">If you must use XRC and the RXM/Verbs combination then you will need to set the environment variable FI_OFI_RXM_USE_SRX=1 and RXM will handle the shared RX details.</div>

No verbs providers are found. Looking through the debug output, I suspect this is the crucial line:<br class="">
<br class="">
libfabric:verbs:fabric:fi_ibv_get_matching_info():1213<info> hints->ep_attr->rx_ctx_cnt != FI_SHARED_CONTEXT. Skipping XRC FI_EP_MSG endpoints<br class="">
<br class="">
I take it that the underlying hardware is only compatible with FI_PROTO_RDMA_CM_IB_XRC protocol for MSG endpoints, and it looks like I need to have FI_SHARED_CONTEXT enabled for these endpoints to be supported. I’m having some trouble understanding the implications
of using FI_SHARED_CONTEXT. If I only ever use one endpoint, is there any functional or performance impact to setting this? I’d rather not change to using shared contexts unconditionally, so is there a good way for me to detect this situation other than to
do a maximally permissive fi_getinfo and iterate through the verbs results?<br class="">

Thanks,<br class="">
