NAME
-
pmbench - measure the performance of PM using pmtest
-
SYNOPSIS
-
pmbench -network network1[,network2] [-host host1[,host2]] [options]
-
DESCRIPTION
-
Pmbench measures PM performance use pmtest.
-
tt>Pmbench measures round trip time and bandwidth.
- OPTIONS
-
-
-network network1[,network2]
-
The network1 specifies the network name defined in
the scorehosts.db file.
You must specifie network1.
If network1 is shmem device, network2 is used

Otherwith, if host is not specified,
node 0 and node 1 in configuration file is used.
-
-burst
-
Show a burst transfer bandwidth instead of
ping-pong transfer round trip time.
-
-zerocopy[=vread|vwrite]
-
Show a remote memory transfer bandwidth instead of
ping-pong transfer round trip time.
If vread is specifies, remote memory read is used.
If vwrite is specifies, remote memory write is used.
If network is shmem device, default is vread,
otherwith vwrite.
-
-len length[,length...]
-
Length byte messages are used for testing.
Default are 4, 8, 16, 32, 48, 64, 96, 128, 192, 256, 384, 512, 768, 1024
