The following problems have been reported during testing of the SPECseis96. Proposed fixes are also noted. Please forward any problems encountered to 'hpgsupport@spec.org' for inclusion in this list. Problem 1: Phase 3 is most sensitive to validation errors. Occassionally, results are correct for Phase 3 even when the phase does not verify. Workaround: Indicate the validation problem in submitted results and discuss in SPEC HPG. Problem 2: NFS demons can become overloaded during disk I/O when multiple tasks write to the same file. Symptoms are excessively long write times, and gaps in files. This problem is very common on workstation clusters, and sometimes is seen on SMP's. Workaround: Compile 'sbfio.c' with -DLOCK to invoke NFS file locking Problem 3: Programs hang during the imaging phase of the 3D migration runs on machines running PVM. Most commonly occurs on SMP's. The cause is long messages swamping the PVM demon. Workaround: Compile 'message.c' with -DSERIAL to serialize message passing during transpose operations. On SMP's that support System V shared memory operations, -DSHMEM can be used to substitute shared memory for the transpose. Proposed fix: Add blocking to the 'jsend/jrecv' routines to send long messages in more manageable pieces. Problem 4: On SMP's supporting system V shared memory only a single job may be run at a time, due to using a fixed key for shared memory segments. Workaround: Run one job at a time. Proposed fix: Add support for generating unique shared memory keys.
