Re: [OMPI users] ARM/Allinea DDT

2018-04-12 Thread Charles A Taylor

Understood.  But since the OpenMPI versions in question are not listed as 
supported on the ARM/Allinea product page, I thought I’d ask if it is 
_supposed_ to work before bothering folks with details.

In the meantime, ARM/Allinea has responded so I’ll provide them with the 
details.  But, in short, DDT can’t seem to attach to the 3.0 processes/ranks 
and just hangs trying.  Using the same code, that doesn’t happen with OpenMPI 
1.10.2 nor IntelMPI 5.1.1.  This is under RHEL 7.4 and launching with srun 
under SLURM 16.05.11 (for those who want to know).

Thanks for the replies,

Charlie

Special Track: GPU - Accelerator
Virtualization Call for PapersVirtualization technologies constitute a key
enabling factor for flexible resource managementin modern data centers, and
particularly in cloud environments. Cloud providers need tomanage complex
infrastructures in a seamless fashion to support the highly dynamic
andheterogeneous workloads and hosted applications customers deploy.
Similarly, HPCenvironments have been increasingly adopting techniques that
enable flexible managementof vast computing and networking resources, close
to marginal provisioning cost, which isunprecedented in the history of
scientific and commercial computing.Various virtualization technologies
contribute to the overall picture in different ways: machinevirtualization,
with its capability to enable consolidation of multiple underutilized
servers withheterogeneous software and operating systems (OSes), and its
capability to live-migrate afully operating virtual machine (VM) with a
very short downtime, enables novel and dynamicways to manage physical
servers; OS-level virtualization (i.e., containerization), with
itscapability to isolate multiple user-space environments and to allow for
their coexistencewithin the same OS kernel, promises to provide many of
the advantages of machine virtualization with high levels of responsiveness
and performance; I/O Virtualization allows physical network interfaces to
take traffic from multiple VMs or containers; network virtualization, with
its capability to create logical network overlays that are independent of
theunderlying physical topology is furthermore enabling virtualization of
HPC infrastructures. PublicationAccepted papers will be published in a
Springer LNCS proceedings volume.Topics of InterestThe VHPC program
committee solicits original, high-quality submissions related

[OMPI users] error building openmpi-3.0.1 on Linux with gcc or Sun C and Java-10

Hi,

I've tried to install openmpi-3.0.1 on my "SUSE Linux Enterprise Server 12.3

2018-04-12 Thread Kawashima, Takahiro

Siegmar,

Thanks for your report. But it is a known issue and will be fixed in Open MPI 
v3.0.2.

  https://github.com/open-mpi/ompi/pull/5029

If you want it now in v3.0.x series, try the latest nightly snapshot.

[OMPI users] OMPI sendrecv bugs?

2018-04-12 Thread Kaiming Ouyang

Hi all,
I am trying to test the bandwidth of intra-MPI send and recv. The code is
attached here. When I give the input 2048 (namely each process will send
and receive 2GB data), the program reported:
Read 2147479552, expected 2147483648, errno = 95
Read 2147479552, expected 2147483648, errno = 98
Read 2147479552, expected 2147483648, errno = 98
Read 2147479552, expected 2147483648, errno = 98

Does this mean Openmpi does not support the send and recv where data size
is larger than 2GB, or is there a bug in my code? Thank you.
