Gridcoin weekly project update - 22/Jan/18

Here is another weekly Gridcoin project stats update where I look at the project chart developments and highlight an interesting aspect. This time I will be comparing CPU vs GPU projects and how they have been performing in the past months.

We currently have 27 whitelisted projects in the Gridcoin network, with each project performing differently in terms of earnings and contribution to the overall BOINC network. But if you would compare CPU projects vs GPU projects overall, would you see any performance differences between them?

To check this, I compiled an overview of 24 out 27 whitelisted projects and looked at their performance in the last 5 months. DrugDiscovery@home, Sourcefinder and ODLK1 are excluded because they were only whitelisted during this period.

In table 1 and 2, I have presented all CPU and GPU projects with the following indicators:

• Team Gridcoin overall RAC contribution
• GRC per 1k system RAC
• USD per 1k system RAC

table 1 – CPU projects (source: [1], [2] and [3]))

table 2 – GPU projects (source: [1], [2] and [3]))

In table 3, I have summarised the CPU and GPU weighted averages for all 3 indicators to make the overall comparison.

table 3 – CPU vs GPU overall (source: [1], [2] and [3]))

Looking at table 2 & 3 there are clear differences between individual projects for both CPU and GPU projects. On the other hand, when you look at the summary of the three indicators in table 3, there seems to be very limited performance differences overall which means the balance between CPU vs GPU projects has remained the same in the last 5 months.

For both CPU and GPU projects the GRC earnings have reduced with 30% while the USD earnings have increased with around 110%. In terms of RAC contribution to the overall BOINC network, team Gridcoin has increased its share with 50% in the last 5 months.

As a final comment, you can of course crunch CPU and GPU projects simultaneously so there is no need to select one or the other!

And here is the table of GRC and USD earnings per 1k system RAC plus the charts for all whitelisted projects. The definitions per indicator can be found below the charts.

(Source: [1], [2] and [3])

Definitions

• Recent Average RAC = The total amount of RAC produced by all systems within the Gridcoin network.
• Team RAC vs Overall RAC % = The proportion of RAC output team Gridcoin has produced as part of the overall RAC for the project.
• GRC per 1k system RAC = The amount of GRC you will receive for a system per 1000 RAC points. Example: You have a system which is running Rosetta@home with a RAC value of 3500. According to the chart on 30-Oct, you should gain 3.5 x 0.42 GRC = 1.47 GRC per day for this system.
• USD per 1k system RAC = The amount of USD you will receive for a system per 1000 RAC points. Example: You have a system which is running NFS@Home with a RAC of 4700. According to the chart on 30-Oct, you should gain 4.7 x $0.29= $1.36 per day for this system.

Gridcoin is an open source cryptocurrency (Ticker: GRC) which securely rewards volunteer computing performed upon the BOINC platform in a decentralized manner on top of proof of stake.

BOINC (Berkeley Open Infrastructure for Network Computing) is a distributed Internet platform and was launched beginning of 2002 and it rewards participants with credits for performed work. BOINC is an application available for multiple Operating Systems and uses the unused CPU and GPU cycles on computers to perform scientific work.
