Dear user The Cray T3E may abort when it fills up the remote message pool on large number of processors during I/O operations. The solution is to add -DRSL_SYNCIO to the CFLAGS setting in MPP/RSL/RSL/makefile.t3e: CFLAGS = -DMPI -DT3D -O $(IDIR) -DRSL_SYNCIO 'Make uninstall' and 'make mpp' in the top level directory for the change to take effect. (This will cause the RSL library to be rebuilt). This only affects the Cray T3E. --- Rotang April 12, 2000
