Re: [mpich-discuss] Mpich over RDMA sample

Okay, let me keep digging. If verbs;ofi_rxm is good, then my understanding is that I should see the RoCE messages over the wire, correct? i.e once I can get the sample application working. Currently, we still see the error as below. I will try to use your patch for interface selection to see what happens. ==== Capability set configuration ==== libfabric provider: verbs;ofi_rxm - IB-0xfe80000000000000 Assertion failed in file src/mpid/ch4/netmod/ofi/init_addrxchg.c at line 151: mapped_table[i] != FI_ADDR_NOTAVAIL Assertion failed in file src/mpid/ch4/netmod/ofi/init_addrxchg.c at line 151: mapped_table[i] != FI_ADDR_NOTAVAIL Assertion failed in file src/mpid/ch4/netmod/ofi/init_addrxchg.c at line 151: mapped_table[i] != FI_ADDR_NOTAVAIL Assertion failed in file src/mpid/ch4/netmod/ofi/init_addrxchg.c at line 151: mapped_table[i] != FI_ADDR_NOTAVAIL Assertion failed in file src/mpid/ch4/netmod/ofi/init_addrxchg.c at line 151: mapped_table[i] != FI_ADDR_NOTAVAIL From: Zhou, Hui <zhouh(a)anl.gov> Date: Tuesday, June 18, 2024 at 11:05 AM To: Niyaz Murshed <Niyaz.Murshed(a)arm.com>, discuss(a)mpich.org <discuss(a)mpich.org> Cc: nd <nd(a)arm.com> Subject: Re: Mpich over RDMA sample Niyaz, FYI -https://urldefense.us/v3/__https://ofiwg.github.io/libfabric/v1.21.0/man/fi_provider.7.html__;!!G_uCfscf7eWS!cn5cXL4QAe2E8ZgxXqVCAl7c3CheHJj61w7oq7Xjax_lCc5i0vxNUMPTygWv434dybYxB1kttyfXaQHq74c$ Hui ________________________________ From: Niyaz Murshed <Niyaz.Murshed(a)arm.com> Sent: Tuesday, June 18, 2024 11:00 AM To: Zhou, Hui <zhouh(a)anl.gov>; discuss(a)mpich.org <discuss(a)mpich.org> Cc: nd <nd(a)arm.com> Subject: Re: Mpich over RDMA sample Hi Hui, When you say message semantic, do you mean endpoint type message ?

"ofi_rxm" is the utility provider that provides the message semantics. "verbs;ofi_rxm" is the provider combination you want.

ZjQcmQRYFpfptBannerEnd When testing with Libfabric, verbs provider is selected. I did have to use “-e msg -d mlx5_1” so that it selects verbs. I was checking if there is anything like that for mpich sample tests. Else might need to do some hack in the code to force the selection of verbs.

Sounds like it was selecting the sockets or tcp provider rather than a provider that support RoCE. I am not exactly sure whether the verbs provider will do that. If you can confirm the provider using libfabric tests, then you can try forcing MPICH to use that provider by setting the FI_PROVIDER environment variable. -- Hui Zhou From: Niyaz Murshed via discuss <discuss(a)mpich.org> Date: Wednesday, June 12, 2024 at 9:03 AM To: discuss(a)mpich.org <discuss(a)mpich.org> Cc: Niyaz Murshed <Niyaz.Murshed(a)arm.com>, nd <nd(a)arm.com> Subject: [mpich-discuss] Mpich over RDMA sample Hello, I am trying to learn about MPICH and its performance over RDMA.

Is there any way to test commination over RoCE ? For eg. I was able to test it for libfabric using the below sample that comes along with libfabric to test RMA. Is there something similar for MPICH ? or use the current sample to use RoCE by some parameter?

Hi Hui, When you say message semantic, do you mean endpoint type message ? Mpich is running over libfabric. When I run sample application on libfabric, it does have message endpoints over RMA.

"ofi_rxm" is the utility provider that provides the message semantics. "verbs;ofi_rxm" is the provider combination you want.

The "verbs" provider alone does not provide the message semantics we needed for MPI. "ofi_rxm" is the utility provider that provides the message semantics. "verbs;ofi_rxm" is the provider combination you want.

Is there any way to test commination over RoCE ? For eg. I was able to test it for libfabric using the below sample that comes along with libfabric to test RMA. Is there something similar for MPICH ? or use the current sample to use RoCE by some parameter?

discuss(a)mpich.org <discuss(a)mpich.org> Cc: nd <nd(a)arm.com> Subject: Re: mpi hello-world error It is picking the first interface from libfabric providers. It appears libfabric is "randomly" ordering the interfaces, which explains the inconsistencies. The interface identified at mpirun is not passed down to the individual MPI processes, which should be passed down and be used to select the correct provider instance. We'll add that to our TODOs.

Hi Hui, I have set the env variable to FI_PROVIDER=verbs , after thich I get the below. libfabric provider: verbs;ofi_rxm - IB-0xfe80000000000000 It does not chose just “verbs” , it selects verbs;ofi_rxf I am wanting to select the below: provider: verbs, score = 0, pref = 0, FI_SOCKADDR_IN [16] 192.168.2.200 I would really like to thank you for such fast responses.

Sounds like it was selecting the sockets or tcp provider rather than a provider that support RoCE. I am not exactly sure whether the verbs provider will do that.

Is there any way to test commination over RoCE ? For eg. I was able to test it for libfabric using the below sample that comes along with libfabric to test RMA. Is there something similar for MPICH ? or use the current sample to use RoCE by some parameter?

discuss(a)mpich.org <discuss(a)mpich.org> Cc: nd <nd(a)arm.com> Subject: Re: mpi hello-world error It is picking the first interface from libfabric providers. It appears libfabric is "randomly" ordering the interfaces, which explains the inconsistencies. The interface identified at mpirun is not passed down to the individual MPI processes, which should be passed down and be used to select the correct provider instance. We'll add that to our TODOs.

Re: [mpich-discuss] Mpich over RDMA sample

Hi Hui, I would still need some assistance in this. I am not able to make mpich chose verbs provider ☹ With the log : provider: verbs, score = 0, pref = 0, FI_SOCKADDR_IN [16] 192.168.2.200 Is my assumption to think the above log represent that verbs provider knows about a path to 192.168.2.200 ? How does the application hello-world decide which provider to use?

discuss(a)mpich.org <discuss(a)mpich.org> Cc: nd <nd(a)arm.com> Subject: Re: mpi hello-world error It is picking the first interface from libfabric providers. It appears libfabric is "randomly" ordering the interfaces, which explains the inconsistencies. The interface identified at mpirun is not passed down to the individual MPI processes, which should be passed down and be used to select the correct provider instance. We'll add that to our TODOs.
