I encountered a problem when I was testing the scalapck testing code named "pzludriver.f" provided by Intel CKML library to solving matrix equations. The problem is that when each processor access more than 2GB RAM, someerror indicated as follows:
forrtl: severe (174): SIGSEGV, segmentation fault occurred
rank 0 in job 54 compute-1-8.local_33089 caused collective abort of
all ranks exit status of rank 0: return code 174
Weare using 64-bit Intel Fortran Compiler in Linux Version-9.0 to generate ".exe" File. The hardware platform we used for testing is ten-blades Dell Cluster, each blade with 8GB RAM and two 64 bit CPU and Linux OS.
We have successfully finished the matrix filling, but we cant pass through the solving process. Ill appreciate for any suggestions.
