We are planning to buy soon a cluster of dual athlons, and i was
just checking the performance of one node before finally deciding
wheter i will take dual athlon (1.2Ghz) or dual-pentium (1.0Ghz).
For this, i use the benchmark test used for amber6, but i got
this error :
./benchmark
p0_25196: (3.688622) xx_shmalloc: returning NULL; requested
3668840 bytes
p0_25196: (3.688689) p4_shmalloc returning NULL; request =
3668840 bytes
You can increase the amount of memory by setting the environment
variable
P4_GLOBMEMSIZE (in bytes)
p0_25196: p4_error: alloc_p4_msg failed: 0
As i am not familiar with MPIC, i was wondering if the message
comes from amber, so i need to recompile it, or from mpi, and in
this case, where can i modify this environment variable ?
In my script, or in the mpi implementation ?
Thanks a lot in advance, Stef
