You can try to embed your remote script in a here document, then for faster processing store it in a variable.
Code:
scriptcode=$(
cat << "ENDSCRIPT"
echo "running on `uname -n`"
ps -fp `grep \`tail -1 /z/y/x | awk '{print $30}'\``
ENDSCRIPT
)

echo "scriptcode is
$scriptcode"

for hsts in `cat /a/b/c//hsts.txt`  # hsts.txt file contains all the hosts
do
   ssh ${id}@${hsts} "$scriptcode"
done

binlog.auth(4)						     Kernel Interfaces Manual						    binlog.auth(4)

NAME
binlog.auth - authorization file for accepting remote binlog messages SYNOPSIS
# format: Each fully qualified host name on a separate line hostname.domain_name DESCRIPTION
The /etc/binlog.auth file specifies which remote hosts are allowed to forward binlog messages to the local host. For the sake of security, only messages coming from remote hosts listed in the local /etc/binlog.auth file will be logged by the binlogd daemon. Each remote host name should appear in a separate line in /etc/binlog.auth. A line started with the # character is considered as a comment and is thus ignored. A host name must be a complete domain name such as trout.zk3.dec.com. If a domain host name is given, it must either appear in the local /etc/hosts file or be able to be resolved by the name server. Note that a host name can have at most as many characters as defined by the MAXHOSTNAMELEN constant in <sys/param.h>, although each line in the /etc/binlog.auth file can have up to 512 characters. The /etc/binlog.auth file must be owned by root and has a permission of 0600. If the /etc/binlog.auth file does not exist or it exists but is empty or has no valid remote host names in it, the system will assume no remote host is allowed to forward binlog messages to the local host. To invoke a new version of the /etc/binlog.auth file, run the following command (as the super user) to re-initialize the binlogd daemon: kill -HUP `cat /var/run/binlogd.pid` EXAMPLES
The following example provides a typical authorization file: # format: Each fully qualified host name on a separate line c3poid.rvo.dec.com r2d2id.ckt.dec.com FILES
