Running on 4 node error MPI Errors[320798736]
 

Good morning boys , i have a question. Until this moment i used 3 nodes from 24 cores (v3) for node; and all goes well. Yesterday i buyed another node , in this case is a double xeon (v4). In this moment only one cpu function because the second is without cooling. As Always i started my system with the new node , but as i write in the object i return an error MPI.

The log is this:
SEVERE [star.base.neo.ClientNotifyHandler]: MPI Errors[320798736] : MPI_Waitall: Internal MPI error: Filename too long

MPI Errors[320798736] : MPI_Waitall: Internal MPI error: Filename too long

Now i try with some test:
Node 1 , 2 and 3 are the old nodes ; node 4 is the newone

Test 1:
Node 1,2,3,4 with only a core for node --test passed
Node 1,2,3,4 with 16 cores for node -- test passed
Node 1,2,4 with 24 core for node 1 and 2 and 16 cores for node 4 --test passed
Node 1,2,3 with 24 cores for nodes and node 4 with 16 cores -- test failed
Node 1,2,3 with 24 cores for nodes and node 4 with 1 cores -- test failed

Anyone have a idea?

Is your cluster running a windows system by chance?

Yes, Windows 10....

i chaged the mpi from ibm to intel. The error is Always present but isn't the same:

Now i add the second cpu , so mi situation is 4 nodes with two cpu for node:
Node 1: 2x e5 2658v3 (24 cores)
Node 2: 2x e5 2658v3 (24 cores)
Node 3: 2x e5 2658v3 (24 cores)
Node 4: 2x e5 2683v4 (32 cores)

Today i started a new session , with two tests:

-1 : 4 nodes with 24 cores for node ---passed
-2 : 3 nodes with 24 cores for nodes and node 4 with 32 cores --- failed

Is it possible that all node must have the same cores?
But how with 3 nodes i could use 2 node with 24 cores and one with 16 cores?
