Open Resilient Cluster Manager (ORCM)

December 7, 2009 at 12:00 pm PST

Cisco announced this past weekend a new open source effort that is being launched under the Open MPI project umbrella named the Open Resilient Cluster Manager (or “OpenRCM”, or — my personal favorite — “ORCM”.  Say it 10 times fast!).

The Open MPI community is pleased to announce the establishment of a new subproject built upon the Open MPI code base. Using work initially contributed by Cisco Systems, the Open Resilient Cluster Manager is an open source project released under the Open MPI [BSD] license focused on development of an “always on” resource manager for systems spanning the range from embedded to very large clusters.

The ORCM web site neatly lays out the project goals:

  • Maintain operation of running applications in the face of single or multiple failures of any given process within that application.
  • Proactively detect incipient failures (hardware and/or software) and respond appropriately to maintain overall system operation.
  • Support both MPI and non-MPI applications.
  • Provide a research platform for exploring new concepts and methods in resilient systems.

“That’s great,” you say.  “But why on earth do we need yet another cluster resource manager?”

MPI Forum RCE podcast recorded

Just a quick note today: Brock Palen and I just recorded an interview with Bill Gropp, MPI-2.2 Chair, and Rich Graham, MPI-3.0 Chair.  Brock should be posting the podcast up on within a week or so.

Technorati claim code

November 24, 2009 at 12:00 pm PST

Pardon the intrusion folks, I need to re-claim this blog on Technorati, so I need to publish this claim code where Technorati can find it.  I think I can delete this entry after Technorati verifies me; we’ll see…

Here is is, Technorati: GUYH9B8ZVYKR

OpenPA v1.0.2 release

November 23, 2009 at 12:00 pm PST

EDITOR’S NOTE: As with entries about hwloc, this announcement entry is a little off the beaten track for high performance networks, but it is definitely related and relevant.

The good folks at Argonne National Labs have released OpenPA (Portable Atomics) v1.0.2.  It’s a small library that implements processor atomic operations in a portable fashion (i.e., across platforms, compilers, etc. — including inline assembly support).  Here’s a link to the release announcement and the general OpenPA web site.

While OpenPA is not directly related to high performance networking, it is highly useful to have an extremely efficient/optimized set of atomic operations when multiple threads are sharing a single resource — such as a network resource.  Hence, this companion library is quite useful in driving full utilization of common network resources.  I keep beating the same drum: as core counts are going up, little utilities like OpenPA and hwloc are going to be very, very important to extract all the performance from your server that you expect to get.

More MPI Forum feedback needed

November 20, 2009 at 12:00 pm PST

First the Fortran WG asked for some specific guidance (thank you very much for all who replied!), now the main Forum itself is conducting a community-wide survey to solicit feedback to help shape the MPI-3 standards process.  To protect from spam, the survey requires a password: mpi3.

In this survey, the MPI Forum is asking as many people as possible for feedback on the MPI-3 process — what features to include, what features to not include, etc.

We encourage you to forward this survey on to as many interested and relevant parties as possible.

It will take approximately 10 minutes to complete the questionnaire.
