We are procuring new cluster systems using commodity multicore processors by Intel, Sun, AMD, and IBM. I am wondering if there are any requirements for these systems to use Sequoia in terms of software and hardware.

Administrator We are running RHEL5/Fedora Core6 on our machines and we use MPICH2 for our cluster backend (MVAPICH2 with VAPI for infiniband support). We have mostly tested on x86, but PowerPC running linux seems to be okay. For SMP runtimes, we need stable thread support. The disk runtime appears the most fragile as we need good AIO support. Fedora5+ seems to be okay there. We have done no testing under AIX or Solaris. It is known that the disk and SMP backends do *not* work under OSX. I don't have enough spare machines to test the cluster backend, but since we use threading there, I'm not confident in things working. Administrator SMP is actually up and running, we just haven't pushed out the code yet into a public release, but that is the next one to go out after some code cleanup. We've only tested deeply on x86 machines, but we can hand off an SMP backend (which uses Pthreads) if you are up for testing on potentially fragile code. I'm going to be out of town until August 12th, which is when we hope to push out the runtime. If you would like to start working with things sooner, I can put you in contact with another Sequoia developer who can make the runtime code available to you and tell you how to get things compiled. |
